Vitamin C
Uses
Vitamin C is a water-soluble vitamin that has a number of biological functions.
Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.
For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.
3 StarsReliable and relatively consistent scientific data showing a substantial health benefit.
2 StarsContradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
1 StarFor an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.
This supplement has been used in connection with the following health conditions:
| Used for | Why |
|---|---|
3 Stars Athletic Performance and Reducing Pain and Speeding Muscle Strength Recovery after Intense Exercise 400 mg daily for several days before and after intense exercise | Taking vitamin C for several days before and after intense exercise may reduce pain and speed muscle strength recovery. Most research has demonstrated that strenuous exercise increases production of harmful substances called free radicals, which can damage muscle tissue and result in inflammation and muscle soreness. Exercising in cities or smoggy areas also increases exposure to free radicals. Antioxidants, including and vitamin E, neutralize free radicals before they can damage the body, so antioxidants may aid in exercise recovery. Regular exercise increases the efficiency of the antioxidant defense system, potentially reducing the amount of supplemental antioxidants that might otherwise be needed for protection. However, at least theoretically, supplements of antioxidant vitamins may be beneficial for older or untrained people or athletes who are undertaking an especially vigorous training protocol or athletic event. Placebo-controlled research, some of it double-blind, has shown that taking 400 to 3,000 mg of vitamin C per day for several days before and after intense exercise may reduce pain and speed up muscle strength recovery. However, taking vitamin C only after such exercise was not effective in another double-blind study. While some research has reported that vitamin E supplementation in the amount of 800 to 1,200 IU per day reduces biochemical measures of free radical activity and muscle damage caused by strenuous exercise, several studies have not found such benefits, and no research has investigated the effect of vitamin E on performance-related measures of strenuous exercise recovery. A combination of 90 mg per day of coenzyme Q10 and a very small amount of vitamin E did not produce any protective effects for marathon runners in one double-blind trial, while in another double-blind trial a combination of 50 mg per day of zinc and 3 mg per day of copper significantly reduced evidence of post-exercise free radical activity. In most well-controlled studies, exercise performance has not been shown to improve following supplementation with vitamin C, unless a deficiency exists, as might occur in athletes with unhealthy or irrational eating patterns. Similarly, vitamin E has not benefited exercise performance, except possibly at high altitudes. |
3 Stars Bronchitis 200 mg daily | In a double-blind study of elderly patients hospitalized with acute bronchitis, those given vitamin C improved to a significantly greater extent than those who were given a placebo. In a double-blind study of elderly patients hospitalized with acute bronchitis, those who were given 200 mg per day of improved to a significantly greater extent than those who were given a placebo. The common cold may lead to bronchitis in susceptible people, and numerous controlled studies, some double-blind, have shown that vitamin C supplements can decrease the severity and duration of the common cold in otherwise healthy people. Vitamin C and vitamin E may prevent oxidative damage to the lung lipids by environmental pollution and cigarette smoke exposure. It has been suggested that amounts in excess of the RDA (recommended dietary allowance) are necessary to protect against the air pollution levels currently present in North America, although it is not known how much vitamin E is needed to produce that protective effect. |
3 Stars Bruising 400 to 800 mg daily, with flavonoids | Vitamin C supplements have been shown to reduce bruising in people with low vitamin C intake. Doctors often suggest that people who experience easy bruising supplement with 100 mg to 3 grams of per day for several months. Controlled research is limited, but vitamin C supplements have been shown to reduce bruising in people with low vitamin C intake.Flavonoids are often recommended along with vitamin C. Flavonoids are vitamin-like substances that can help strengthen capillaries and therefore may also help with bruising. Flavonoids may also increase the effectiveness of vitamin C; citrus flavonoids, in particular, improve the absorption of vitamin C. Older preliminary research suggested that vitamin C, 400–800 mg per day, in combination with 400–800 mg per day of the flavonoid, hesperidin, reduced bruising in menopausal women. A small, preliminary trial in Germany gave three people with progressive pigmented purpura (a chronic bruising disorder) 1,000 mg per day of vitamin C and 100 mg per day of the flavonoid rutoside. After four weeks, noticeable bruising was no longer apparent and did not recur in the three month period after treatment was stopped. Controlled research is needed to better establish whether vitamin C and flavonoids are effective for easy bruising. |
3 Stars Capillary Fragility Treat deficiency with up to 1 gram daily | In cases of deficiency, vitamin C has been shown to increase capillary strength, in seniors and people with diabetes in particular. Severe deficiency (scurvy) is a well-recognized but uncommon cause of increased capillary fragility. Whether vitamin C supplementation can help capillary fragility in people who do not have scurvy is less clear. Patients undergoing dialysis may develop low levels of vitamin C, which can lead to capillary fragility, but giving dialysis patients 50 mg of vitamin C per day had no effect on capillary fragility in one study. People with kidney failure and those undergoing dialysis should not supplement with more than 100 mg per day, unless supervised by a doctor. According to preliminary studies, vitamin C may reduce capillary weakness in diabetics, who often have low blood levels of vitamin C compared to non-diabetics. In a double-blind trial, elderly people with low vitamin C levels and capillary fragility were helped with supplementation of one gram per day of vitamin C. |
3 Stars Common Cold and Sore Throat 1 to 4 grams daily | Studies have shown that taking vitamin C may make your cold shorter and less severe. A review of 21 controlled trials using 1 to 8 grams of per day found that “in each of the twenty-one studies, vitamin C reduced the duration of episodes and the severity of the symptoms of the common cold by an average of 23%.” The optimum amount of vitamin C to take for cold treatment remains in debate but may be as high as 1 to 3 grams per day, considerably more than the 120 to 200 mg per day that has been suggested as optimal intake for healthy adults. A review of 23 controlled trials found that vitamin C supplementation produces a greater benefit for children than for adults. The same review found that a daily amount of 2 grams or more was superior to a daily amount of 1 gram at reducing the duration of cold symptoms. |
3 Stars Gingivitis 300 mg daily | If you are deficient in vitamin C, supplementing with this vitamin may improve your overall gum health. People who are deficient in may be at increased risk for periodontal disease. When a group of people with periodontitis who normally consumed only 20–35 mg of vitamin C per day were given an additional 70 mg per day, objective improvement of periodontal tissue occurred in only six weeks. It makes sense for people who have a low vitamin C intake (e.g., people who eat few fruits and vegetables) to supplement with vitamin C in order to improve gingival health. |
3 Stars Glaucoma At least 2 grams daily | Supplementing with vitamin C may help reduce intraocular pressure. Several studies have shown that supplementing with can significantly reduce elevated intraocular pressure in individuals with glaucoma. These studies used at least 2 grams per day of vitamin C; much larger amounts were sometimes given. Higher quantities of vitamin C appeared to be more effective than smaller amounts. Doctors often suggest that people with glaucoma take vitamin C to “bowel tolerance.” The bowel-tolerance level is determined by progressively increasing vitamin C intake until loose stools or abdominal pain occurs, and then reducing the amount slightly, to a level that does not cause these symptoms. The bowel tolerance level varies considerably from person to person, usually ranging from about 5 to 20 or more grams per day. Vitamin C does not cure glaucoma and must be used continually to maintain a reduction in intraocular pressure. |
3 Stars Hypertension 500 to 1,500 mg daily | Higher intake of vitamin C is associated with reduced risk of high blood pressure, and some doctors recommend people with hypertension supplement with vitamin C. As a free radical scavenger, vitamin C is thought to mitigate oxidative injury to blood vessels that contributes to high blood pressure. A meta-analysis of findings from 18 observational studies noted people with high blood pressure have lower blood vitamin C levels than people with normal blood pressure. One of these studies found those with the highest vitamin C levels, a reflection of both dietary and supplement intake, had a 22% lower risk of hypertension than those with the lowest vitamin C levels. In another pooled analysis of 8 randomized controlled trials that included a combined total of 614 participants with high blood pressure, vitamin C supplementation resulted in an average systolic blood pressure decrease of 4.09 mmHg and an average diastolic blood pressure decrease of 2.30 mmHg. Doses of at least 500 mg per day and interventions lasting six weeks or longer had increased effectiveness. |
3 Stars Infection 1 to 4 grams daily | Vitamin C has antiviral activity, and may help prevent viral infections or, in the case of the common cold, reduce the severity and duration of an infection. has antiviral activity, and may help prevent viral infections or, in the case of the common cold, reduce the severity and duration of an infection. Most studies on the common cold used 1 to 4 grams of vitamin C per day. |
3 Stars Male Infertility and Sperm Agglutination 1,000 mg daily | Vitamin C protects sperm from oxidative damage and keeps sperm from sticking together. protects sperm from oxidative damage. Supplementing vitamin C improves the quality of sperm in smokers. When sperm stick together (a condition called agglutination), fertility is reduced. Vitamin C reduces sperm agglutination, and supplementation with 200–1,000 mg per day increased the fertility of men with this condition in a controlled study. Many doctors recommend 1 gram of vitamin C per day for infertile men, particularly those diagnosed with sperm agglutination. However, a double-blind trial studying the effects of combined vitamin C and vitamin E supplementation found no improvements in semen quality among men with low sperm motility. |
3 Stars Scurvy Refer to label instructions | Although scurvy is uncommon in Western societies, many doctors believe that most people consume less than optimal amounts of vitamin C, especially smokers. Although scurvy (severe vitamin C deficiency) is uncommon in Western societies, many doctors believe that most people consume less than optimal amounts. Fatigue, easy bruising, and bleeding gums are early signs of vitamin C deficiency that occur long before frank scurvy develops. Smokers have low levels of vitamin C and require a higher daily intake to maintain normal vitamin C levels. |
3 Stars Stress 100 to 3,000 mg daily | Studies have shown that supplementing with vitamin C helps to normalize stress-hormone levels. Animal studies suggest that supplementing with can reduce blood levels of stress-related hormones and other measures of stress. Controlled studies of athletes have shown that vitamin C supplementation (1,000 to 1,500 mg per day) can reduce stress hormone levels after intense exercise. Surgery patients given 2,000 mg per day of vitamin C during the week before and after surgery had a more rapid return to normal of several stress-related hormones compared with patients not given vitamin C. In a double-blind trial, young adults took 3,000 mg per day of vitamin C for two weeks, then were given a psychological stress test involving public speaking and mental arithmetic. Compared with a placebo group, those taking vitamin C rated themselves less stressed, scored better on an anxiety questionnaire, had smaller elevations of blood pressure, and returned sooner to lower levels of an adrenal stress hormone following the stress test. |
3 Stars Sunburn (Vitamin E) 2,000 to 3,000 mg vitamin C and 1,000 to 2,000 IU vitamin E | Antioxidants may protect the skin from sunburn due to free radical–producing ultraviolet rays. Combinations of vitamin E and C offer protection against ultraviolet rays. Antioxidants may protect the skin from sunburn due to free radical–producing ultraviolet rays. Combinations of 1,000 to 2,000 IU per day of vitamin E and 2,000 to 3,000 mg per day of , but neither given alone, have a significant protective effect against ultraviolet rays, according to double-blind studies. Oral synthetic beta-carotene alone was not found to provide effective protection when given in amounts of 15 mg per day or for only a few weeks’ time in larger amounts of 60 to 90 mg per day, but it has been effective either in very large (180 mg per day) amounts or in smaller amounts (30 mg per day) in combination with topical sunscreen. Natural sources of beta-carotene or other carotenoids have been more consistently shown to protect against sunburn. One controlled study found that taking a supplement of natural carotenoids (almost all of which was beta-carotene) in daily amounts of 30 mg, 60 mg, and 90 mg gave progressively more protection against ultraviolet rays. In another controlled study, either 24 mg per day of natural beta-carotene or 24 mg per day of a carotenoid combination of equal amounts beta-carotene, lutein, and lycopene helped protect skin from ultraviolet rays. A preliminary study compared synthetic lycopene (10.1 mg per day), a natural tomato extract containing 9.8 mg of lycopene per day plus additional amounts of other carotenoids, and a solubilized tomato drink (designed to increase lycopene absorption) containing 8.2 mg of lycopene plus additional amounts of other carotenoids. After 12 weeks, only the two tomato-based products were shown to give significant protection against burning by ultraviolet light. Still other trials have tested combinations of several antioxidants. One preliminary study found that a daily combination of beta-carotene (6 mg), lycopene (6 mg), vitamin E (15 IU), and selenium for seven weeks protected against ultraviolet light. However, a double-blind trial of a combination of smaller amounts of several carotenoids, vitamins C and E, selenium, and proanthocyanidins did not find significant UV protection compared with placebo. Similarly, in a controlled trial, a combination of selenium, copper, and vitamins was found to be ineffective. It should be noted that while oral protection from sunburn has been demonstrated with several types of antioxidants, the degree of protection (typically less than an SPF of 2) is much less than that provided by currently available topical sunscreens. On the other hand, these modest effects will provide some added protection to skin areas where sunscreen is also used and will give a small amount of protection to sun-exposed areas where sunscreen is not applied. However, oral protection from sunburn is not instantaneous; maximum effects are not reached until these antioxidants have been used for about eight to ten weeks. |
3 Stars Wound Healing 1 to 3 grams daily | Taking vitamin C may promote connective tissue repair. is needed to make collagen (connective tissue) that strengthens skin, muscles, and blood vessels and to ensure proper wound healing. Severe injury appears to increase vitamin C requirements, and vitamin C deficiency causes delayed healing. Preliminary human studies suggest that vitamin C supplementation in non-deficient people can speed healing of various types of wounds and trauma, including surgery, minor injuries, herniated intervertebral discs, and skin ulcers. A combination of 1–3 grams per day of vitamin C and 200–900 mg per day of pantothenic acid has produced minor improvements in the strength of healing skin tissue. |
2 Stars Asthma 1,000 to 1,500 mg daily | Supplementing with vitamin C reduces the tendency of the bronchial passages to go into spasm, an action that has been confirmed in double-blind research. Supplementation with 1 gram of per day reduces the tendency of the bronchial passages to go into spasm, an action that has been confirmed in double-blind research. Beneficial effects of short-term vitamin C supplementation (i.e., less than three days) have been observed. In double-blind trials, supplementation with 1,000 to 1,500 mg of vitamin C per day for 2 to 14 days prevented attacks of exercise-induced asthma. Two other preliminary trials found that vitamin C supplementation reduced bronchial reactivity to metacholine, a drug that causes bronchial constriction. However, other studies, including two double-blind trials, have failed to corroborate these findings. The only double-blind trial of a long duration found that vitamin C supplementation (1 gram per day for 14 weeks) reduced the severity and frequency of attacks among Nigerian adults with asthma. A buffered form of vitamin C (such as sodium ascorbate or calcium ascorbate) may work better for some asthmatics than regular vitamin C (ascorbic acid). |
2 Stars Atherosclerosis 250 mg twice per day | Supplementing with vitamin C may help reverse the progression of atherosclerosis and protect against heart disease. Experimentally increasing homocysteine levels in humans has led to temporary dysfunction of the cells lining blood vessels. Researchers are concerned this dysfunction may be linked to atherosclerosis and heart disease. has been reported in one controlled study to reverse the dysfunction caused by increases in homocysteine. Vitamin C also protects LDL. Despite the protective mechanisms attributed to vitamin C, some research has been unable to link vitamin C intake to protection against heart disease. These negative trials have mostly been conducted using people who consume 90 mg of vitamin C per day or more—a level beyond which further protection of LDL may not occur. Studies of people who eat foods containing lower amounts of vitamin C have been able to show a link between dietary vitamin C and protection from heart disease. Therefore, leading vitamin C researchers have begun to suggest that vitamin C may be important in preventing heart disease, but only up to 100–200 mg of intake per day. In a double-blind trial, supplementation with 250 mg of timed-release vitamin C twice daily for three years resulted in a 15% reduction in the progression of atherosclerosis, compared with placebo. Many doctors suggest that people take vitamin C—often 1 gram per day—despite the fact that research does not yet support levels higher than 500 mg per day. |
2 Stars Athletic Performance and Vitamin C Deficiency If deficient: 100 to 200 mg daily | Antioxidants, including vitamin C, neutralize exercise-related free radicals before they can damage the body, so antioxidants may aid in exercise recovery. Especially in cases of vitamin C deficiency, supplementing with the vitamin may improve exercise performance. Most research has demonstrated that strenuous exercise increases production of harmful substances called free radicals, which can damage muscle tissue and result in inflammation and muscle soreness. Exercising in cities or smoggy areas also increases exposure to free radicals. Antioxidants, including and vitamin E, neutralize free radicals before they can damage the body, so antioxidants may aid in exercise recovery. Regular exercise increases the efficiency of the antioxidant defense system, potentially reducing the amount of supplemental antioxidants that might otherwise be needed for protection. However, at least theoretically, supplements of antioxidant vitamins may be beneficial for older or untrained people or athletes who are undertaking an especially vigorous training protocol or athletic event. Placebo-controlled research, some of it double-blind, has shown that taking 400 to 3,000 mg of vitamin C per day for several days before and after intense exercise may reduce pain and speed up muscle strength recovery. However, taking vitamin C only after such exercise was not effective in another double-blind study. While some research has reported that vitamin E supplementation in the amount of 800 to 1,200 IU per day reduces biochemical measures of free radical activity and muscle damage caused by strenuous exercise, several studies have not found such benefits, and no research has investigated the effect of vitamin E on performance-related measures of strenuous exercise recovery. A combination of 90 mg per day of coenzyme Q10 and a very small amount of vitamin E did not produce any protective effects for marathon runners in one double-blind trial, while in another double-blind trial a combination of 50 mg per day of zinc and 3 mg per day of copper significantly reduced evidence of post-exercise free radical activity. In most well-controlled studies, exercise performance has not been shown to improve following supplementation with vitamin C, unless a deficiency exists, as might occur in athletes with unhealthy or irrational eating patterns. Similarly, vitamin E has not benefited exercise performance, except possibly at high altitudes. |
2 Stars Autism 1 gram per 20 lbs (9 kg) body weight per day | In one trial, autistic children given vitamin C had less severe symptoms than those taking placebo, possibly because vitamin C affects a hormone pathway typically disturbed in children with autism. In one double-blind trial lasting ten weeks, autistic children given 1 gram per day for each 20 pounds of body weight showed a reduction in symptom severity compared with placebo. The authors speculate that vitamin C may play a positive role because of its known effects on a hormone pathway typically disturbed in children with autism. |
2 Stars Cold Sores (Flavonoids) 200 mg with 200 mg flavonoids, three to five times daily | Vitamin C plus flavonoids may help speed cold sore healing. has been shown to inactivate herpes viruses in the test tube. In one study, people with herpes infections received either a placebo or 200 mg of vitamin C plus 200 mg of flavonoids, each taken three to five times per day. Compared with the placebo, vitamin C and flavonoids reduced the duration of symptoms by 57%. |
2 Stars Depression 500 mg twice a day | In a double-blind study, the combination of vitamin C and an antidepressant drug (fluoxetine) was significantly more effective than the antidepressant alone. In a double-blind study of Egyptian children with depression, the combination of vitamin C (500 mg twice a day) and an antidepressant drug (fluoxetine) was significantly more effective than fluoxetine alone. |
2 Stars Dysmenorrhea (Rutin, Vitamin B3 (Niacin)) 200 mg niacin daily, 300 mg vitamin C daily, and 60 mg rutin daily througout menstrual cycle; for cramps: 100 mg niacin every two to three hours | Supplementing with a combination of vitamin B3, vitamin C, and the flavonoid rutin resulted in a 90% effectiveness for relieving menstrual cramps in one study. The niacin form of vitamin B3 has been reported to be effective in relieving menstrual cramps in 87% of a group of women taking 200 mg of niacin per day throughout the menstrual cycle. They then took 100 mg every two or three hours while experiencing menstrual cramps. In a follow-up study, this protocol was combined with 300 mg of vitamin C and 60 mg of the flavonoid rutin per day, which resulted in a 90% effectiveness for relieving menstrual cramps. Since these two preliminary studies were published many years ago, no further research has explored the relationship between niacin and dysmenorrhea. Niacin may not be effective unless taken for seven to ten days before the onset of menstrual flow. |
2 Stars Endometriosis (Vitamin E) 1,000 mg vitamin C and 1,200 IU vitamin E daily | A combination of vitamin C and vitamin E can help lessen the pain of endometriosis. In a double-blind study of women with pelvic pain presumed to be due to endometriosis, supplementation with vitamin E (1,200 IU per day) and (1,000 mg per day) for eight weeks resulted in an improvement of pain in 43% of women, whereas none of the women receiving a placebo reported pain relief. |
2 Stars Female Infertility and Luteal Phase Defect 750 mg daily | Vitamin C has been shown to improve fertility in woman with a uterine condition known as luteal phase defect. In some women, infertility is due to a hormonal abnormality known as luteal phase defect. In this condition, the uterine lining does not develop and mature properly, presumably because of a deficiency of the hormone progesterone. In a study of infertile women with luteal phase defect, supplementation with 750 mg of per day for up to six months resulted in a pregnancy rate of 25%, compared with a rate of 11% in an untreated control group, a statistically significant difference. |
2 Stars Gastritis 5 grams daily | Vitamin C may reduce free radical damage in the stomach lining in the case of gastritis caused by the bacteriaH. pylori. When H. pylori causes gastritis, free radical levels rise in the stomach lining. These unstable molecules contribute to inflammation and damage to the stomach lining. , an antioxidant that helps quench free radical molecules, is low in the stomach juice of people with chronic gastritis. This deficiency may be the link between chronic gastritis and the increased risk of stomach cancer. When people with gastritis took 500 mg of vitamin C twice a day, vitamin C levels in their gastric juice rose, though not to normal levels. In another trial, vitamin C supplementation (5 grams per day divided into several doses for four weeks) appeared to eliminate H. pylori infection. While no direct evidence proves that taking vitamin C reduces gastritis symptoms, scientists widely believe that any agent capable of knocking out H. pylori should help people with this condition. |
2 Stars Gingivitis (Flavonoids) 300 mg of vitamin C, plus 300 mg of flavonoids daily | In one study, supplementing with vitamin C plus flavonoids improved gum health in a group of people with gingivitis. People who are deficient in may be at increased risk for periodontal disease. When a group of people with periodontitis who normally consumed only 20–35 mg of vitamin C per day were given an additional 70 mg per day, objective improvement of periodontal tissue occurred in only six weeks. It makes sense for people who have a low vitamin C intake (e.g., people who eat few fruits and vegetables) to supplement with vitamin C in order to improve gingival health. For people who consume adequate amounts of vitamin C in their diet, several studies have found that supplemental vitamin C has no additional therapeutic effect. Research, including double-blind evidence, shows that vitamin C fails to significantly reduce gingival inflammation in people who are not vitamin C deficient. In one study, administration of vitamin C plus flavonoids (300 mg per day of each) did improve gingival health in a group of people with gingivitis; there was less improvement, however, when vitamin C was given without flavonoids. Preliminary evidence has suggested that flavonoids by themselves may reduce inflammation of the gums. |
2 Stars Gout 0.5 to 8 grams daily | Supplementing with vitamin C might reduce the risk of gout attacks, as it appears to help reduce uric acid levels. In one small study, people who took 4 grams of (but not lower amounts) had an increase in urinary excretion of uric acid within a few hours, and those who took 8 grams of vitamin C per day for several days had a reduction in serum uric acid levels. Thus, supplemental vitamin C could, in theory, reduce the risk of gout attacks. However, the authors of this study warned that taking large amounts of vitamin C could also trigger an acute attack of gout by abruptly changing uric acid levels in the body. Another study showed that taking lower amounts of vitamin C (500 mg per day) for two months significantly reduced blood levels of uric acid, especially in people whose initial uric acid levels were elevated. For people with a history of gout attacks, it seems reasonable to begin vitamin C supplementation at 500 mg per day, and to increase the amount gradually if uric acid levels do not decrease. |
2 Stars Immune Function Consult a qualified healthcare practitioner | Vitamin C stimulates the immune system. While taking it has only a small effect in preventing colds, it does significantly reduce the duration of a cold when taken at the onset. Most, but not all, double-blind studies have shown that elderly people have better immune function and reduced infection rates when taking a multiple vitamin-mineral formula. In one double-blind trial, supplements of 100 mcg per day of selenium and 20 mg per day of zinc, with or without additional , vitamin E, and beta-carotene, reduced infections in elderly people, though vitamins without minerals had no effect. Burn victims have also experienced fewer infections after receiving trace mineral supplements in double-blind research. These studies suggest that trace minerals may be the most important micronutrients for enhancing immunity and preventing infections in the elderly. stimulates the immune system by both elevating interferon levels and enhancing the activity of certain immune cells. Two studies came to opposite conclusions about the ability of vitamin C to improve immune function in the elderly, and two other studies did not agree on whether vitamin C could protect people from hepatitis. However, a review of 20 double-blind studies concluded that while several grams of vitamin C per day has only a small effect in preventing colds, when taken at the onset of a cold, it does significantly reduce the duration of a cold. In controlled reports studying people doing heavy exercise, cold frequency was reduced an average of 50% with vitamin C supplements ranging from 600 to 1,000 mg per day. Thus, the overall effect of vitamin C on immune function is unclear, and its usefulness may vary according to the situation. A combination of antioxidants vitamin A, , and vitamin E significantly improved immune cell number and activity compared with placebo in a group of hospitalized elderly people. Daily intake of a 1,000 mg vitamin C plus 200 IU vitamin E for four months improved several measures of immune function in a preliminary study. To what extent immune-boosting combinations of antioxidants actually reduce the risk of infection remains unknown. |
2 Stars Influenza 100 mg daily | Supplementing with vitamin C may reduce your flu risk. Dockworkers given 100 mg of each day for ten months caught influenza 28% less often than did their coworkers not taking vitamin C. Of those who did develop the flu, the average duration of illness was 10% less in those taking vitamin C than in those not taking the vitamin. Other trials have reported that taking vitamin C in high amounts (2 grams every hour for 12 hours) can lead to rapid improvement of influenza infections. Such high amounts, however, should only be used under the supervision of a healthcare professional. |
2 Stars Pancreatic Insufficiency 540 mg daily | Taking antioxidant supplements, such as vitamin C, may lessen pain and prevent pancreatitis recurrences. There are few controlled trials of antioxidant supplementation to patients with pancreatitis. One small controlled study of acute pancreatitis patients found that sodium selenite at a dose of 50 micrograms (mcg) daily resulted in decreased levels of a marker of free radical activity, and no patient deaths occurred. In a small double-blind trial including recurrent acute and chronic pancreatitis patients, supplements providing daily doses of 600 mcg selenium, 9,000 IU beta-carotene, 540 mg vitamin C, 270 IU vitamin E, and 2,000 mg methionine significantly reduced pain, normalized several blood measure of antioxidant levels and free radical activity, and prevented acute recurrences of pancreatitis. These researches later reported that continuing antioxidant treatment in these patients for up to five years or more significantly reduced the total number of days spent in the hospital and resulted in 78% of patients becoming pain-free and 88% returning to work. |
2 Stars Parkinson’s Disease (Vitamin E) 3,000 mg of vitamin C and 3,200 IU of vitamin E | Supplementing with vitamins C and E may help people with early Parkinson’s disease delay the need for medication. Some preliminary studies have indicated that high dietary intakes of antioxidant nutrients, especially vitamin E, are associated with a low risk of Parkinson’s disease, even though Parkinson’s patients are not deficient in vitamin E. The correlation between protection from Parkinson’s and dietary vitamin E may be not be due to the vitamin E itself, however. Legumes (beans and peas) contain relatively high amounts of vitamin E. Independent of their vitamin E content, consumption of legumes has been associated with low risk of Parkinson’s disease. In other words, high vitamin E intake may be a marker for diets high in legumes, and legumes may protect against Parkinson’s disease for reasons unrelated to their vitamin E content. Interest in the relationship between antioxidants and Parkinson’s disease led to a preliminary trial using high amounts of and vitamin E in early Parkinson’s disease and to a large ten-year controlled trial of high amounts of vitamin E combined with the drug deprenyl. In the trial combining vitamins C and E, people with early Parkinson’s disease given 750 mg of vitamin C and 800 IU of vitamin E four times each day (totaling 3,000 mg of vitamin C and 3,200 IU of vitamin E per day) were able to delay the need for drug therapy (i.e., L-dopa or selegiline) by an average of about two and a half years, compared with those not taking the vitamins. The ten-year controlled trial used 2,000 IU of vitamin E per day found no benefit in slowing or improving the disease. The difference in the outcomes between these two trials might be due to the inclusion of vitamin C and/or the higher amount of vitamin E used in the successful trial. However, the difference might also be due to a better study design in the trial that found vitamin E to be ineffective. The amounts of vitamin E used in the above trials were very high, because raising antioxidant levels in brain tissue is quite difficult to achieve. In fact, some researchers have found that even extremely high intakes of vitamin E (4,000 IU per day) failed to increase brain vitamin E levels. The difficulty in increasing brain vitamin E levels may explain the poor results of the large, controlled trial. |
2 Stars Pre- and Post-Surgery Health and Vitamin C Deficiency 100 to 250 mg once or twice per day | Vitamin C supports immune function and is a critical nutrient for wound healing. Supplementing with it may decrease the risk of excessive bleeding in the surgical setting. deficiency can be detrimental to immune function in hospitalized patients, and one study found that half of surgery patients recovering at home had low dietary intakes of vitamin C. Vitamin C is also a critical nutrient for wound healing, but studies of vitamin C supplementation have shown only minor effects on the healing of surgical wounds. Vitamin C deficiency also can increase the risk of excessive bleeding in the surgical setting. |
2 Stars Pregnancy and Postpartum Support 100 mg daily | Supplementing with vitamin C during pregnancy may reduce the risk of premature rupture of membranes (PROM) and may improve lung function in the child. Premature rupture of membranes (PROM) affects 10 to 20% of all pregnancies. It is an important cause of preterm delivery and is associated with increased rates of complications in both the mother and child. In a double-blind study, supplementing with 100 mg of per day, beginning in the twentieth week of pregnancy, reduced the incidence of PROM by 74%. The women in this study were consuming only about 65 mg of vitamin C per day in their diet, which is less than the RDA of 80 to 85 mg per day for pregnant women. In a double-blind study of pregnant smokers, supplementation with 500 mg per day of vitamin C, beginning at 23 weeks of pregnancy or earlier and continuing until delivery, improved lung function and decreased the incidence of wheezing in the offspring. |
2 Stars Schizophrenia Consult a qualified healthcare practitioner | People with schizophrenia may require more vitamin C than the general population. In one trial, vitamin C reduced hallucinations, suspiciousness, and disorganized thoughts. Up to 6 grams daily of has been reported to be beneficial for people with schizophrenia; in one case the addition of 400 IU daily of vitamin E enhanced this benefit. A small preliminary trial using 8 grams daily of vitamin C showed decreases in hallucinations, suspiciousness, and unusual and disorganized thoughts in 77% of schizophrenic patients. In all reported cases, patients were also being treated with sychiatric medications. Some early studies found no difference between blood and urine vitamin C levels in schizophrenics and non-schizophrenics, either before or after supplementation. However, later studies found that blood and urine levels of vitamin C were lower in schizophrenics than in non-schizophrenics before and after a single 1,000 mg “load” of vitamin C was taken. After four weeks of daily supplementation with 1,000 mg of vitamin C, blood levels became the same, but urinary levels remained lower in the schizophrenic group, leading the researchers to conclude that the amount of vitamin C required by people with schizophrenia may be greater than that of the general population. |
2 Stars Skin Ulcers 1,000 mg daily | Supplementing with vitamin C may help prevent skin ulcers and speed healing. Antioxidants such as , vitamin E, and glutathione are depleted in healing skin tissue. One animal study found that vitamin E (alpha-tocopherol) applied to the skin shortened the healing time of skin ulcers. Another animal study reported that administration of oral vitamin E before skin lesions were introduced into the skin prevented some of the tissue damage associated with the development of pressure ulcers. A controlled human trial found that 400 IU of vitamin E daily improved the results of skin graft surgery for chronic venous ulcers. No further research has investigated the potential benefit of vitamin E for skin ulcers. Animal research has suggested that vitamin C may help prevent skin ulcers, and in a preliminary study, elderly patients with pressure ulcers had lower blood levels of vitamin C than did ulcer-free patients. Supplementation with vitamin C (3 grams per day) increased the speed of healing of leg ulcers in patients with a blood disorder called thalassemia, according to a double-blind study. And while a double-blind trial of surgical patients with pressure ulcers found that supplementation with 500 mg of vitamin C twice a day accelerated ulcer healing, a similar double-blind trial found no difference in the effectiveness of either 20 mg per day or 1,000 mg per day of vitamin C. |
2 Stars Sprains and Strains 250 to 500 mg with meals and at bedtime | Vitamin C is needed to make collagen, the “glue” that strengthens connective tissue. Vitamin C supplementation can speed healing of various types of trauma. Antioxidant supplements, including and vitamin E, may help prevent exercise-related muscle injuries by neutralizing free radicals produced during strenuous activities. Controlled research, some of it double-blind, has shown that 400–3,000 mg per day of vitamin C may reduce pain and speed up muscle strength recovery after intense exercise. Reductions in blood indicators of muscle damage and free radical activity have also been reported for supplementation with 400–1,200 IU per day of vitamin E in most studies, but no measurable benefits in exercise recovery have been reported. A combination of 90 mg per day of coenzyme Q10 and a very small amount of vitamin E did not produce any protective effects in one double-blind trial. is needed to make collagen, the “glue” that strengthens connective tissue. Injury, at least when severe, appears to increase vitamin C requirements, and vitamin C deficiency causes delayed healing from injury. Preliminary human studies have suggested that vitamin C supplementation in non-deficient people can speed healing of various types of trauma, including musculoskeletal injuries, but double-blind research has not confirmed these effects for athletic injuries, which included sprains and strains. |
2 Stars Sunburn (Vitamin E) Apply a formula containing 2% vitamin E and 5% vitamin C before sun exposure | Studies have found sunscreen-like effects from topical application of the vitamin C and vitamin E combination. Antioxidants have been studied as topical agents for protection against sunburn. Animal studies have found sunscreen-like effects from topical application of a and vitamin E combination, and a controlled human study reported ultraviolet protection from the use of a lotion containing 0.02% to 0.05% of the selenium-containing amino acid known as selenomethionine. The topical use of the hormone melatonin has been shown to protect human skin against ultraviolet rays in double-blind research. A double-blind human trial tested topical vitamins C and E and melatonin, alone and in combinations, and found the highest degrees of protection from combination formulations containing 2% vitamin E, 5% vitamin C, and 1% to 2.5% melatonin. Other studies in which topical antioxidants were applied after ultraviolet exposure have found no benefits. |
2 Stars Type 1 Diabetes 1,000 mg vitamin C plus 400 IU vitamin E daily | Supplementing with vitamin C may benefit people with type 1 diabetes by preventing free radical damage and protecting blood vessels. Vitamin C is important for lowering oxidative stress and preventing oxidative tissue damage linked to high glucose levels in people with diabetes. Vitamin C levels have been found to be lower in people with type 1 diabetes compared to healthy people, and low levels have been correlated with markers of decreased cardiovascular health in those with type 1 diabetes. In addition, because vitamin C uptake by cells is enhanced by insulin and suppressed by high glucose levels, people with type 1 diabetes have more difficulty meeting their cellular and tissue needs for vitamin C. In a placebo-controlled trial, 1,000 mg vitamin C along with 800 IU vitamin E per day for six months improved blood vessel function in participants with type 1 diabetes. Another placebo-controlled trial found the high dose of 6 grams of vitamin C per day for six months improved markers of capillary health. Several studies show vitamin C may protect blood vessels from free radical damage during the vulnerable periods of high blood glucose in subjects with type 1 diabetes. A small one-month study in children with type 1 diabetes found no effect of supplementation with 250 mg per day of vitamin C on vascular health. Another trial in nine type 1 diabetes-affected adolescents investigated doses of vitamin C ranging from 250–750 mg per day, depending on weight, combined with vitamin E for six weeks and saw no change in vascular function. Whether these negative findings reflect study factors such as low dose, short duration, and small number of participants is unclear. |
2 Stars Type 2 Diabetes 500 mg one to two times daily | Supplementing with vitamin C may lower blood glucose levels and protect cardiovascular health. Vitamin C, at a dose of 500 mg twice per day, was found to reduce fasting blood glucose levels, although not HbA1c, after four months in a placebo-controlled trial. A meta-analysis of other controlled trials found vitamin C supplementation can reduce blood glucose levels (but not HbA1c) in people with type 2 diabetes, and is especially effective in those who are older and those who have taken vitamin C for 30 days or more. Through its anti-inflammatory and antioxidant effects, vitamin C has been shown to lower blood pressure and improve cardiovascular health in people with type 2 diabetes. In addition, like other antioxidants, vitamin C reduces formation of advanced glycation end-products (AGEs), which cause widespread damage to proteins and DNA. Antioxidants like vitamins C and E protect against damage to micro-vessels and therefore have the potential to help prevent type 2 diabetes complications such as retinopathy, nephropathy, and neuropathy. Furthermore, low vitamin C levels in blood and in the eye have been correlated with increased risk of retinopathy. In a pilot study, a combination supplement with vitamin C and other antioxidant vitamins, minerals, and plant extracts improved vision in subjects with type 2 diabetes and early stage retinopathy. High-dose vitamin C supplementation has been reported to interfere with some devices for self-monitoring of blood glucose levels. This can raise the risk of overtreatment leading to hypoglycemia. Therefore it is important that people with type 2 diabetes who rely on self-monitoring glucose devices talk with their healthcare provider before starting a vitamin C supplement. |
2 Stars Urinary Tract Infection Refer to label instructions | Supplementing with vitamin C may treat acute UTIs and help people who are prone to recurrent UTIs. Many doctors recommend 5,000 mg or more of per day for an acute UTI, as well as long-term supplementation for people who are prone to recurrent UTIs. Vitamin C has been shown to inhibit the growth of E. coli, the most common bacterial cause of UTIs. In addition, supplementation with 4,000 mg or more of vitamin C per day, results in a slight increase in the acidity of the urine, creating an “unfriendly” environment for some infection-causing bacteria. In one controlled trial, pregnant women who supplemented with 100 mg of vitamin C per day experienced 56% less UTI frequency, compared with a placebo. |
1 Star Age-Related Cognitive Decline Refer to label instructions | Use of vitamin C, alone or with vitamin E, has been associated with better cognitive function and a reduced risk of certain forms of dementia (not including Alzheimer’s disease). Use of or vitamin E supplements, or both, has been associated with better cognitive function and a reduced risk of certain forms of dementia (not including Alzheimer’s disease). Clinical trials of these antioxidants are needed to confirm the possible benefits suggested by this study. |
1 Star Alcohol Withdrawal Refer to label instructions | Vitamin C appears to help the body rid itself of alcohol. Alcohol-related anxiety may also be improved by a combination of vitamin C, vitamin B6, niacin, and vitamin E, though the high amounts B vitamins studied need a doctor’s supervision. The daily combination of 3 grams of , 3 grams of niacin, 600 mg of vitamin B6, and 600 IU of vitamin E has been used by researchers from the University of Mississippi Medical Center in an attempt to reduce anxiety and depression in alcoholics. Although the effect of vitamin supplementation was no better than placebo in treating alcohol-associated depression, the vitamins did result in a significant drop in anxiety within three weeks of use. Because of possible side effects, anyone taking such high amounts of niacin and vitamin B6 must do so only under the care of a doctor. Although the incidence of B-complex deficiencies is known to be high in alcoholics, the incidence of other vitamin deficiencies remains less clear. Nonetheless, deficiencies of vitamin A, vitamin D, vitamin E, and are seen in many alcoholics. While some reports have suggested it may be safer for alcoholics to supplement with beta-carotene instead of vitamin A, potential problems accompany the use of either vitamin A or beta-carotene in correcting the deficiency induced by alcoholism. These problems result in part because the combinations of alcohol and vitamin A or alcohol and beta-carotene appear to increase potential damage to the liver. Thus, vitamin A-depleted alcoholics require a doctor’s intervention, including supplementation with vitamin A and beta-carotene accompanied by assessment of liver function. Supplementing with vitamin C, on the other hand, appears to help the body rid itself of alcohol. Some doctors recommend 1 to 3 grams per day of vitamin C. |
1 Star Asthma (Vitamin E, Selenium) Refer to label instructions | There is some evidence that a combination of antioxidants vitamin E, vitamin C, and selenium may help prevent asthma thought to be caused by air pollution. There is some evidence that combinations of antioxidants such as vitamin E, vitamin C, and selenium may help improve symptoms of asthma throught to be caused by air pollution. In one double-blind study, 46 Dutch bicyclists were randomly assigned to receive a placebo or 100 mg of vitamin E and 500 mg of vitamin C daily for 15 weeks. Lung function was measured before and after each training session on 380 different occasions, and ambient ozone concentrations were measured during each training session. After analysis, researchers concluded that bicyclists with the vitamins C and E blunted the adverse effects of ozone on measures of lung function. In another double-blind study, 17 adults (18 to 39 years old) were randomly assigned to receive either 400 IU per day of vitamin E and 500 mg per day of vitamin C or a placebo for five weeks. Tests showing improved measures of lung function led researchers to conclude that supplementation with vitamins C and E inhibited the decline in pulmonary function induced in asthmatics by exposure to air pollutants. Also using a double-blind design, another study of 158 children with asthma living in Mexico City were randomly assigned to receive, a daily supplement containing 50 mg of vitamin E and 250 mg of vitamin C or a placebo. Tests results suggested that supplementing with vitamins C and E may reduce the adverse effect of ozone exposure on lung function of children with moderate to severe asthma. |
1 Star Bipolar Disorder Refer to label instructions | Vitamin C helps the body reduce its load of vanadium, a mineral that adversely influences bipolar disorder. It has improved symptoms of depression and mania in some studies. helps the body to reduce its load of vanadium and this has been studied for its possible role in treatment of bipolar disorder. A double-blind trial found that both manic and depressed bipolar patients were significantly improved after one-time administration of 3 grams of vitamin C, compared with a placebo. The same study found that both manic and depressed patients did better on a reduced-vanadium diet compared to a normal diet. Another double-blind study reported that 4 grams per day of vitamin C in combination with a drug known as EDTA (which also helps remove elements such as vanadium from the body) was helpful to depressed bipolar patients but not to those experiencing mania. Until more is known, people with bipolar illness should avoid supplements containing vanadium and consider supplementing with vitamin C. |
1 Star Cataracts 500 to 1,000 mg daily | Supplementing with vitamin C, an important nutrient for healthy vision, has been linked with lower risk of developing cataracts. People with low blood levels of antioxidants and those who eat few antioxidant-rich fruits and vegetables have been reported to be at high risk for cataracts. The major antioxidants in the lens of the eye are and glutathione (a molecule composed of three amino acids). Vitamin C is needed to activate vitamin E, which in turn activates glutathione. Both nutrients are important for healthy vision. People who take multivitamins or any supplements containing vitamins C or E for more than 10 years have been reported to have a 60% lower risk of forming a cataract. Vitamin C levels in the eye decrease with age. However, supplementing with vitamin C prevents this decrease and has been linked to a lower risk of developing cataracts. Healthy people are more likely to take vitamin C and vitamin E supplements than those with cataracts according to some, but not all, studies. Dietary vitamin C intake has not been consistently associated with protection from cataracts. Nonetheless, because people who supplement with vitamin C have developed far fewer cataracts in some research, doctors often recommend 500 to 1,000 mg of vitamin C supplementation as part of a cataract prevention program. The difference between successful and unsuccessful trials may be tied to the length of time people actually supplement with vitamin C. In one preliminary study, people taking vitamin C for at least ten years showed a dramatic reduction in cataract risk, but those taking vitamin C for less than ten years showed no evidence of protection at all. |
1 Star Childhood Diseases Refer to label instructions | Vitamin C enhances the immune system and may protect against viral infections, including measles and chicken pox. has been demonstrated in test tube, animal, and human studies to have immune-enhancing and direct antiviral properties. Preliminary observations made on the effect of vitamin C on viral infections have involved both measles and chicken pox. An active immune system uses vitamin C rapidly, and blood levels fall in children with bacterial or viral infections. Reduced immune cell activity has been observed in people with measles, but in one preliminary study, supplementation with 250 mg daily of vitamin C in children 18 months to 3 years old had no impact on the course of the illness. The authors of this study admit that this amount of vitamin C may have been too low to bring about an observable increase in immune cell activity and thus an increase in speed of recovery. |
1 Star Chronic Obstructive Pulmonary Disease Refer to label instructions | In one study, people who got more vitamin C from their diet were less likely to be diagnosed with bronchitis, however, vitamin C has not been studied in relation to COPD. A review of nutrition and lung health reported that people with a higher dietary intake of were less likely to be diagnosed with bronchitis. As yet, the effects of supplementing with vitamin C in people with COPD have not been studied. |
1 Star Colon Cancer Refer to label instructions | Vitamin C has been shown to improve precancerous conditions in at-risk people. Women, but not men, who took vitamin C supplements were reported to have a reduced risk of colon cancer, according to a preliminary report. Familial polyposis is a disease that usually leads to colon cancer. In a double-blind study, supplementation with 3 grams per day of vitamin C for nine months led to a reduction in the number of precancerous polyps in people with familial polyposis. In another controlled trial, combining vitamin C with vitamin A and vitamin E led to a dramatic reduction in the recurrence of adenomatous polyps—another precancerous condition of the colon. However, other trials attempting to prevent recurrence of adenomatous polyps using vitamin C alone or in combination with other vitamins have reported no therapeutic effect or only weak trends favoring the group given supplements. Therefore, the ability of vitamin C supplementation to reduce recurrences of precancerous polyps remains unproven. Whether long-term supplementation with vitamin C would directly help in the prevention of colon cancer has not yet been studied. |
1 Star Ear Infections Refer to label instructions | Supplementing with vitamin C stimulates the immune system and may help prevent ear infections. supplementation has been reported to stimulate immune function. As a result, some doctors recommend between 500 mg and 1,000 mg of vitamin C per day for people with ear infections. Nonetheless, vitamin C supplementation has not been studied by itself in people with ear infections. |
1 Star Eczema Refer to label instructions | Vitamin C might be beneficial in treating eczema by affecting the immune system. In 1989, Medical World News reported that researchers from the University of Texas found that , at 50–75 mg per 2.2 pounds of body weight, reduced symptoms of eczema in a double-blind trial. In theory, vitamin C might be beneficial in treating eczema by affecting the immune system, but further research has yet to investigate any role for this vitamin in people with eczema. |
1 Star Gallstones Refer to label instructions | Vitamin C is needed for the body to convert cholesterol to bile acids and may help reduce symptoms of gallstones. is needed to convert cholesterol to bile acids. In theory, such a conversion should reduce gallstone risks. Women who have higher blood levels of vitamin C have a reduced risk of gallstones. Although this does not prove that vitamin C supplements can prevent or treat gallstones, some researchers believe this is plausible. One study reported that people who drink alcohol and take vitamin C supplements have only half the risk of gallstones compared with other drinkers, though the apparent protective effect of vitamin C did not appear in non-drinkers. In another trial, supplementation with vitamin C (500 mg taken four times per day for two weeks before gallbladder surgery) led to improvement in one parameter of gallstone risk (“nucleation time”), though there was no change in the relative level of cholesterol found in bile. While many doctors recommend vitamin C supplementation to people with a history of gallstones, supportive evidence remains preliminary. |
1 Star Hay Fever Refer to label instructions | Vitamin C has antihistamine activity, and supplementing with it has been reported to help people with hay fever. Although has antihistamine activity, and supplementation, in preliminary research, has been reported to help people with hay fever, 2,000 mg of vitamin C per day did not reduce hay fever symptoms in a placebo controlled trial. Thus, while some doctors recommend that hay fever sufferers take 1,000–3,000 mg of vitamin C per day, supportive evidence remains weak. |
1 Star Heart Attack Refer to label instructions | Vitamin C has been reported to protect blood vessels from problems associated with heart attack risk in a variety of ways. has been reported to protect blood vessels from problems associated with heart attack risk in a variety of ways. However, research attempting to link vitamin C directly to protection from heart attacks has been inconsistent. The reason for this discrepancy appears related to the amount of vitamin C intake investigated in these studies. True or marginal vitamin C deficiencies do appear to increase the risk of suffering heart attacks. However, in trials comparing acceptable (i.e., non-deficient) vitamin C levels to even higher levels, additional vitamin C has not been protective. Therefore, though many doctors recommend that people at high risk for heart attack take vitamin C—often 1 gram per day—most evidence currently suggests that consuming as little as 100–200 mg of vitamin C per day from food or supplements may well be sufficient. |
1 Star Heart Attack and Vitamin C Deficiency 100 to 200 mg daily | Taking vitamin C may reduce heart attack risk in people who are deficient. has been reported to protect blood vessels from problems associated with heart attack risk in a variety of ways. However, research attempting to link vitamin C directly to protection from heart attacks has been inconsistent. The reason for this discrepancy appears related to the amount of vitamin C intake investigated in these studies. True or marginal vitamin C deficiencies do appear to increase the risk of suffering heart attacks. However, in trials comparing acceptable (i.e., non-deficient) vitamin C levels to even higher levels, additional vitamin C has not been protective. Therefore, though many doctors recommend that people at high risk for heart attack take vitamin C—often 1 gram per day—most evidence currently suggests that consuming as little as 100–200 mg of vitamin C per day from food or supplements may well be sufficient. |
1 Star Hepatitis Refer to label instructions | Vitamin C may be efffective at preventing hepatitis infection in people receiving blood transfusions and at treating viral hepatitis. in the amount of 2 grams per day was reported in a preliminary trial to prevent hepatitis infection in individuals receiving blood transfusions. This report was followed up by a double-blind trial, in which 3.2 grams per day of vitamin C was reported to have no protective effect against post-transfusion hepatitis. (However, in the latter trial, vitamin C actually reduced the incidence of hepatitis by 29%, although this reduction was not statistically significant.) An older trial suggested that injections of vitamin C may be helpful in treating viral hepatitis. |
1 Star High Cholesterol 500 to 2,000 mg daily | Vitamin C appears to protect LDL cholesterol from oxidative damage and may protect cardiovascular health, but has been found to have little impact on cholesterol levels. appears to protect LDL cholesterol from oxidative damage and its possible role in cardiovascular protection remains uncertain. Some research suggests vitamin C may reduce LDL-cholesterol levels. However, a meta-analysis of randomized controlled trials found vitamin C had no general effect on lipid levels, but decreased total cholesterol levels in younger participants, lowered LDL-cholesterol levels in healthy people, and increased HDL-cholesterol levels in type 2 diabetics, with stronger effects in those with more disturbed levels. Other meta-analyses have not found a statistically significant effect for vitamin C on lipid levels in those with type 2 diabetes. |
1 Star Hives Refer to label instructions | High amounts of vitamin C might help people with hives by lowering histamine levels. In theory, high amounts of might help people with hives by lowering histamine levels. Amounts of at least 2,000 mg daily appear necessary to produce these effects. No research trials have yet explored the clinical effects of vitamin C supplementation in people with hives. |
1 Star Hypoglycemia Refer to label instructions | Vitamin C helps control blood sugar levels in people with diabetes, and since there are similarities in the way the body regulates high and low blood sugar levels, it might be helpful for hypoglycemia as well. Research has shown that supplementing with chromium (200 mcg per day) or magnesium (340 mg per day) can prevent blood sugar levels from falling excessively in people with hypoglycemia. Niacinamide (vitamin B3) has also been found to be helpful for hypoglycemic people. Other nutrients, including , vitamin E, zinc, copper, manganese, and vitamin B6, may help control blood sugar levels in diabetics. Since there are similarities in the way the body regulates high and low blood sugar levels, these nutrients might be helpful for hypoglycemia as well, although the amounts needed for that purpose are not known. |
1 Star Low Back Pain Refer to label instructions | A preliminary report suggested that vitamin C helped many people avoid surgery for their disc-related low back pain. A preliminary report in 1964 suggested that 500–1,000 mg per day of helped many people avoid surgery for their disc-related low back pain. No controlled research has been done to examine this claim further. |
1 Star Macular Degeneration Refer to label instructions | Sunlight triggers oxidative damage in the eye, which in turn can cause macular degeneration. Vitamin C protects against oxidative damage and may reduce macular degeneration risk. Sunlight triggers oxidative damage in the eye, which in turn can cause macular degeneration. Because vitamin C functions as an antioxidant, it has the potential to protect against macular degeneration. However, in a double-blind trial, supplementing with 500 mg of vitamin C daily for eight years did not decrease the incidence of macular degeneration in healthy male physicians. |
1 Star Menopause Refer to label instructions | A combination of vitamin C and the flavonoid hesperidin were reported to relieve hot flashes in menopausal women. In 1964, a preliminary trial reported that 1,200 mg each of and the flavonoid hesperidin taken over the course of the day helped relieve hot flashes. Although placebo effects are strong in women with hot flashes, other treatments used in that trial failed to act as effectively as the flavonoid/vitamin C combination. Since then, researchers have not explored the effects of flavonoids or vitamin C in women with menopausal symptoms. |
1 Star Menorrhagia Refer to label instructions | Vitamin C protects capillaries (small blood vessels) from damage. In so doing, it might protect against the blood loss of menorrhagia. Both and flavonoids protect capillaries (small blood vessels) from damage. In so doing, they might protect against the blood loss of menorrhagia. In one small study, 88% of women with menorrhagia improved when given 200 mg vitamin C and 200 mg flavonoids three times per day. In another study, 70% of women with excessive menstrual bleeding experienced at least a 50% reduction in bleeding after taking a flavonoid product. The preparation used in this study contained 90% diosmin and 10% hesperidin and was given in the amount of 1,000 mg per day, beginning five days prior to the expected start of menstruation and continuing until the end of bleeding for three cycles. |
1 Star Morning Sickness Refer to label instructions | Vitamin K and vitamin C, taken together, may provide relief of morning sickness symptoms for some women. Vitamin K and , taken together, may provide relief of symptoms for some women. In one study, 91% of women who took 5 mg of vitamin K and 25 mg of vitamin C per day reported the complete disappearance of morning sickness within three days. Menadione was removed from the market a number of years ago because of concerns about potential toxicity. Although some doctors still use a combination of vitamin K1 (the most prevalent form of vitamin K in food) and vitamin C for morning sickness, no studies on this treatment have been done. |
1 Star Peptic Ulcer Refer to label instructions | Vitamin C may be useful in treating peptic ulcers because of its ability to help eradicate H. pylori Little is known about the effects of supplementation for people with peptic ulcer. People with gastritis, a related condition, have been found to have low levels of vitamin C in their stomach juice. Vitamin C may also help eradicate H. pylori in people with gastritis. Vitamin C may one day prove to have a therapeutic effect for people with peptic ulcer; however, further research in this area is needed. |
1 Star Sickle Cell Anemia Refer to label instructions | Sickle cell anemia patients tend to have low levels of antioxidants, which protect cells from oxygen-related damage. Supplementing with vitamin C may help correct a deficiency. Antioxidant nutrients protect the body’s cells from oxygen-related damage. Many studies show that sickle cell anemia patients tend to have low blood levels of antioxidants, including carotenoids, vitamin A, vitamin E, and , despite adequate intake. Low blood levels of vitamin E in particular have been associated with higher numbers of diseased cells in children and with greater frequency of symptoms in adults. A small, preliminary trial reported a 44% decrease in the average number of diseased cells in six sickle cell anemia patients given 450 IU vitamin E per day for up to 35 weeks. This effect was maintained as long as supplementation continued. In another preliminary trial, 13 patients with sickle cell anemia were given two supplement combinations for seven to eight months each. The first combination included 109 mg zinc, 153 IU vitamin E, 600 mg , and 400 ml (about 14 ounces) of soybean oil containing 11 grams of linoleic acid and 1.5 grams of alpha linolenic acid. The second combination included 140 IU vitamin E, 600 mg vitamin C, and 20 grams of fish oil containing 6 grams of omega-3 fatty acids. Reduction in diseased cells was observed only during the administration of the first protocol. The authors concluded that zinc was the important difference between the two combinations and may be a protector of red blood cell membranes. Fish oil alone has also been studied. In a double-blind trial, supplementation with menhaden oil, in the amount of 250 mg per 2.2 pounds of body weight per day for one year, reduced the frequency of severe pain episodes by approximately 45%, compared with placebo. This treatment may work by correcting an imbalance between omega-3 and omega-6 fatty acids that occurs in people with sickle cell anemia. |
1 Star Tardive Dyskinesia Refer to label instructions | In some studies, taking vitamin C along with other nutrients appeared to prevent the development of tardive dyskinesia During a ten-year period, doctors at the North Nassau Mental Health Center in New York treated approximately 11,000 people with schizophrenia with a megavitamin regimen that included (up to 4 grams per day), vitamin B3—either as niacin or niacinamide—(up to 4 grams per day), vitamin B6 (up to 800 mg per day), and vitamin E (up to 1,200 IU per day). During that time, not a single new case of TD was seen, even though many of the people were taking neuroleptic drugs. Another psychiatrist who routinely used niacinamide, vitamin C, and vitamin B-complex over a 28-year period rarely saw TD develop in her patients. Further research is needed to determine which nutrients or combinations of nutrients were most important for preventing TD. The amounts of niacinamide and vitamin B6 used in this research may cause significant side effects and may require monitoring by a doctor. |
1 Star Type 1 Diabetes and Diabetic Retinopathy (Selenium, Vitamin A, Vitamin E) Refer to label instructions | Antioxidant nutrients including selenium, vitamin A, vitamin C, and vitamin E may combat free radicals associated with diabetic retinopathy. Because oxidation damage is believed to play a role in the development of diabetic eye damage (retinopathy), antioxidant nutrients might be protective. One doctor has administered a daily regimen of 500 mcg selenium, 800 IU vitamin E, 10,000 IU vitamin A, and 1,000 mg for several years to 20 people with diabetic eye damage (retinopathy). During that time, 19 of the 20 people showed either improvement or no progression of their retinopathy. People who wish to supplement with more than 250 mcg of selenium per day should consult a healthcare practitioner. |
1 Star Vitiligo Refer to label instructions | Vitamin C has been shown to be effective at skin repigmentation in people with vitiligo. A clinical report describes the use of vitamin supplements in the treatment of vitiligo.Folic acid and/or vitamin B12 and levels were abnormally low in most of the 15 people studied. Supplementation with large amounts of folic acid (1–10 mg per day), along with vitamin C (1 gram per day) and intramuscular vitamin B12 injections (1,000 mcg every two weeks), produced marked repigmentation in eight people. These improvements became apparent after three months, but complete repigmentation required one to two years of continuous supplementation. In another study of people with vitiligo, oral supplementation with folic acid (10 mg per day) and vitamin B12 (2,000 mcg per day), combined with sun exposure, resulted in some repigmentation after three to six months in about half of the participants. This combined regimen was more effective than either vitamin supplementation or sun exposure alone. |
How It Works
How to Use It
The recommended dietary allowance (RDA) for vitamin C in nonsmoking adults is 75 mg per day for women and 90 mg per day for men. For smokers, the RDAs are 110 mg per day for women and 125 mg per day for men. Most clinical vitamin C studies have investigated the effects of a broad range of higher vitamin C intakes (100–1,000 mg per day or more), often not looking for (or finding) the “optimal” intake within that range. In terms of heart disease prevention, as little as 100–200 mg of vitamin C appears to be adequate.1 Although some doctors recommend 500–1,000 mg per day or more, additional research is needed to determine whether these larger amounts are necessary. Some vitamin C experts propose that adequate intake be considered 200 mg per day because of evidence that the cells of the human body do not take up any more vitamin C when larger daily amounts are used.2
Some scientists have recommended that healthy people take multi-gram amounts of vitamin C for the prevention of illness. However, little or no research supports this point of view and it remains controversial. Supplementing more results in an excretion level virtually identical to intake, meaning that consuming more vitamin C does not increase the amount that remains in the body.3 On the basis of extensive analysis of published vitamin C studies, researchers at the Linus Pauling Institute at Oregon State University have called for the RDA to be increased, but only to 120 mg.4 This same report reveals that “. . . 90–100 mg vitamin C per day is required for optimum reduction of chronic disease risk in nonsmoking men and women.” Thus, the multiple gram amounts of vitamin C taken by many healthy people may be superfluous.
The studies that ascertained approximately 120–200 mg daily of vitamin C is correct for prevention purposes in healthy people have typically not investigated whether people suffering from various diseases can benefit from larger amounts. In the case of the common cold, a review of published trials found that amounts of 2 grams per day in children appear to be more effective than 1 gram per day in adults, suggesting that large intakes of vitamin C may be more effective than smaller amounts, at least for this condition.5
Ascorbyl palmitate, often sold as “vitamin C ester,” is formed from ascorbic acid and palmitic acid creating a fat-soluble form of vitamin C that is sometimes used as an antioxidant food additive (E number E304). Oral supplements of ascorbyl palmitate are less effective, as it breaks down into its components before being digested.Where to Find It
Citrus fruits, broccoli, red peppers, currants, Brussels sprouts, parsley, potatoes, and strawberries are good sources of vitamin C. Rose hips, harvested from rose bushes and sold as a supplement, are particularly high in vitamin C.
Possible Deficiencies
Although scurvy (severe vitamin C deficiency) is uncommon in Western societies, many doctors believe that most people consume less than optimal amounts. Fatigue, easy bruising, and bleeding gums are early signs of vitamin C deficiency that occur long before frank scurvy develops. Smokers have low levels of vitamin C and require a higher daily intake to maintain normal vitamin C levels. Women with preeclampsia have been found to have lower blood levels of vitamin C than women without the condition.6 Women who have lower blood levels of vitamin C have an increased risk of gallstones.7
People with kidney failure have an increased risk of vitamin C deficiency.8 However, people with kidney failure should take vitamin C only under the supervision of a doctor.
Best Form to Take
Vitamin C can be taken as ascorbic acid (a weak acid) or in buffered forms (such as sodium ascorbate, calcium ascorbate, or other mineral ascorbates). Buffered forms may be less likely to produce gastrointestinal distress, but they may be more likely to deliver excessive amounts of minerals.9
There is some limited evidence to suggest that vitamin C from natural sources (such as citrus extract) is more bioavailable than synthetic vitamin C, although natural vitamin C is more expensive. Therefore, it may make sense to take synthetic vitamin C and to obtain additional flavonoids and supporting nutrients from eating more fruits and vegetables.10
One trial found that Ester-C, a proprietary vitamin C product, was not more bioavailable than ascorbic acid.11
Fat-soluble forms of vitamin C (such as ascorbyl palmitate) are not to be preferred since vitamin C is naturally a water-soluble compound.12
Interactions
Interactions with Supplements, Foods, & Other Compounds
Intake of large amounts of vitamin C can deplete the body of copper13, 14—an essential nutrient. People should be sure to maintain adequate copper intake at higher intakes of vitamin C. Copper is found in many multivitamin-mineral supplements. Vitamin C increases the absorption of iron and should be avoided by people with iron overload diseases (e.g., hemochromatosis, hemosiderosis). Vitamin C helps recycle the antioxidant, vitamin E.

Chemotherapy can injure cancer cells by creating oxidative damage. As a result, some oncologists recommend that patients avoid supplementing antioxidants if they are undergoing chemotherapy. Limited test tube research occasionally does support the idea that an antioxidant can interfere with oxidative damage to cancer cells. However, most scientific research does not support this supposition.

- Carbidopa
A combination of levodopa/carbidopa and vitamin C may be useful for people with Parkinson’s disease whose motor complications are not effectively managed with conventional drug treatment. This combination was administered to people with Parkinson’s disease for 16.8 months in an unblinded, uncontrolled study. The researchers reported that participants who completed the study experienced substantial increases in the number of hours with good functional capacity and were able to reduce their intake of other anti-Parkinsonian drugs. However, 62% of the participants withdrew from the study, citing difficulty in performing voluntary movements as the main reason. Until more research is performed, this drug-nutrient combination must be viewed as preliminary.

A new formulation of selenium (Seleno-Kappacarrageenan) was found to reduce kidney damage and white blood cell–lowering effects of cisplatin in one human study. However, the level used in this study (4,000 mcg per day) is potentially toxic and should only be used under the supervision of a doctor.
- Isosorbide Dinitrate
Some persons taking nitroglycerin or isosorbide mononitrate may find that it loses efficacy over time. This is because the body adapts to the drug, a process known as developing tolerance. One study found that taking 2 grams three times daily of vitamin C can decrease this effect when nitroglycerin patches are simultaneously used. Similar benefits have been confirmed in another study. However, it should be noted that it is also possible to avoid tolerance to these drugs by simply changing the dosing schedule. People taking ISMN or nitroglycerin should talk with their pharmacists about avoiding drug tolerance.

- Nitroglycerin
may help maintain the blood vessel dilation response to nitroglycerin. A double-blind study found that individuals taking 2 grams of vitamin C three times per day did not tend to develop nitroglycerin tolerance over time compared to those taking placebo. In another controlled clinical trial, similar protection was achieved with 500 mg three times daily.
People using long-acting nitroglycerin can avoid tolerance with a ten- to twelve-hour hour nitroglycerin-free period every day. People taking long-acting nitroglycerin should ask their prescribing doctor or pharmacist about preventing nitroglycerin tolerance.

- Acetaminophen
Taking 3 grams vitamin C with acetaminophen has been shown to prolong the amount of time acetaminophen stays in the body. This theoretically might allow people to use less acetaminophen, thereby reducing the risk of side effects. Consult with a doctor about this potential before reducing the amount of acetaminophen. However, increasing the time acetaminophen is in the body might also theoretically increase its toxicity. Consult with a doctor before taking vitamin C along with acetaminophen.

Cyclophosphamide requires activation by the liver through a process called oxidation. In theory, antioxidant nutrients (vitamin A, vitamin E, beta-carotene and others) might interfere with the activation of cyclophosphamide. There is no published research linking antioxidant vitamins to reduced cyclophosphamide effectiveness in cancer treatment. Another animal research report indicated that may increase the effectiveness of cyclophosphamide without producing new side effects. Preliminary human research found that adding antioxidants (beta-carotene, vitamin A, and vitamin E) to cyclophosphamide therapy increased the survival of people with small-cell lung cancer treated with cyclophosphamide. It is too early to know if adding antioxidants to cyclophosphamide for cancer treatment is better than cyclophosphamide alone. Vitamin A can be toxic in high amounts.

Limited test tube research occasionally does support the idea that an antioxidant can interfere with oxidative damage to cancer cells. However, most scientific research does not support this supposition.
A modified form of vitamin A has been reported to work synergistically with chemotherapy in test tube research. appears to increase the effectiveness of chemotherapy in animals and with human breast cancer cells in test tube research. In a double-blind study, Japanese researchers found that the combination of vitamin E, vitamin C, and N-acetyl cysteine (NAC)—all antioxidants—protected against chemotherapy-induced heart damage without interfering with the action of the chemotherapy.
A comprehensive review of antioxidants and chemotherapy leaves open the question of whether supplemental antioxidants definitely help people with chemotherapy side effects, but neither does it show that antioxidants should be avoided for fear that the actions of chemotherapy are interfered with. Although research remains incomplete, the idea that people taking chemotherapy should avoid antioxidants is not supported by scientific research.

- Thioridazine
Taking phenothiazine drugs can stop menstruation in some women. Two women taking phenothiazines similar to perphenazine began menstruating following supplementation with 6 grams of vitamin C each day. Controlled studies are needed to determine whether vitamin C supplementation might benefit women specifically taking perphenazine who are experiencing menstrual changes. Some health practitioners recommend vitamin C supplementation to women who stop menstruating while taking perphenazine. Vitamin C might also enhance the effectiveness of neuroleptic drugs such as perphenazine in the treatment of schizophrenia. One uncontrolled study showed that 10 of 13 individuals experienced a reduction in disorganized thoughts, hallucinations, and suspicious thoughts when 8 grams of vitamin C was added to their daily drug therapy. Controlled studies are needed to show whether people taking perphenazine for schizophrenia might benefit from vitamin C supplementation.

- Warfarin
Although case reports have suggested that vitamin C might increase the activity of anticoagulants in a potentially dangerous way, this interaction has not been confirmed in research studies. In fact, a possible interference by vitamin C with the effect of anticoagulants has also been reported. A 52-year-old woman maintained on 7.5 mg of warfarin per day had a shortening of the blood clotting time which was not corrected by increasing warfarin up to 20 mg per day. Further questioning revealed she had begun taking an unspecified amount of vitamin C each morning. After stopping vitamin C, the blood clotting time returned to desired levels. Based on this and other case reports, people taking warfarin should consult with their physician before taking vitamin C supplements.

Side Effects
Side Effects
Caution: People with the following conditions should consult their doctor before supplementing with vitamin C: glucose-6-phosphate dehydrogenase deficiency, iron overload (hemosiderosis or hemochromatosis), history of kidney stones, or kidney failure.
Some people develop diarrhea after as little as a few grams of vitamin C per day, while others are not bothered by ten times this amount. Strong scientific evidence to define and defend an upper tolerable limit for vitamin C is not available. A review of the available research concluded that high intakes (2–4 grams per day) are well-tolerated by healthy people.15
It is widely (and mistakenly) believed that mothers who consume large amounts of vitamin C during pregnancy are at risk of giving birth to an infant with a higher-than-normal requirement for the vitamin. The concern is that the infant could suffer “rebound scurvy,” a vitamin C deficiency caused by not having this increased need met. Even some medical textbooks have subscribed to this theory.16 In fact, however, the concept of “rebound scurvy” in infants is supported by extremely weak evidence.17 Since the publication in 1965 of the report upon which this mistaken notion is based, millions of women have consumed high amounts of vitamin C during pregnancy and not a single new case of rebound scurvy has been reported.18
A preliminary study found that people who took 500 mg per day of vitamin C supplements for one year had a greater increase in wall thickness of the carotid arteries (vessels in the neck that supply blood to the brain) than those who did not take vitamin C.19 Thickness of carotid artery walls is an indicator of progression of atherosclerosis. Currently, no evidence supports a cause-and-effect relationship for the outcome reported in this study. The vast preponderance of research suggests either a protective or therapeutic effect of vitamin C for heart disease, or no effect at all.
It has been suggested that people who form calcium oxalate kidney stones should avoid vitamin C supplements, because vitamin C can be converted into oxalate and increase urinary oxalate.20, 21 Initially, these concerns were questioned because of potential errors in the laboratory measurement of oxalate.22, 23 However, using newer methodology that rules out this problem, recent evidence shows that as little as 1 gram of vitamin C per day can increase the urinary oxalate levels in some people, even those without a history of kidney stones.24, 25 In one case, 8 grams per day of vitamin C led to dramatic increases in urinary oxalate excretion and kidney stone crystal formation causing bloody urine.26 People with a history of kidney stones should consult a doctor before taking large amounts (1 gram or more per day) of supplemental vitamin C.
Despite possible therapeutic effects of vitamin C in people with diabetes at lower intakes, one case of increased blood sugar levels was reported after taking 4.5 grams per day.27
