About This Condition
Atherosclerosis is hardening of the arteries, a common disease of the major blood vessels characterized by fatty streaks along the vessel walls and by deposits of cholesterol and calcium.
Atherosclerosis of arteries supplying blood to the heart is called coronary artery disease, and it can restrict the flow of blood to the heart, possibly triggering a heart attack. Atherosclerosis of arteries supplying the legs causes a condition called intermittent claudication, which is characterized by pain in the legs after walking short distances.
People with elevated cholesterol levels are much more likely to have atherosclerosis than people with low cholesterol levels. Many important nutritional approaches to protecting against atherosclerosis are aimed at lowering serum cholesterol levels.
People with diabetes are also at very high risk for atherosclerosis, as are people with elevated triglycerides and high homocysteine.
Symptoms
Atherosclerosis is typically a silent disease until one of the many late-stage vascular manifestations intervenes. Some people with atherosclerosis may experience angina (chest pain) or intermittent claudication (leg cramps and pain) on exertion. Symptoms such as these develop gradually as the disease progresses.
Healthy Lifestyle Tips
Virtually all doctors acknowledge the abundant evidence that smoking is directly linked to atherosclerosis and heart disease.1 Quitting smoking protects many people from atherosclerosis and heart disease, and is a critical step in the process of disease prevention.2, 3
Obesity,4 type A behavior (time conscious, impatient, and aggressive), stress,5 and sedentary lifestyle6 are all associated with an increased risk of atherosclerosis; interventions designed to change these risk factors are linked to protection from this condition.7
Aggressive verbal or physical responses when angry have been consistently related to coronary atherosclerosis in numerous studies.8, 9, 10 A low level of social support, especially when combined with a high level of outwardly expressed anger has also been associated with accelerated progression of coronary atherosclerosis.11
The right diet is the key to managing many diseases and to improving general quality of life. For this condition, scientific research has found benefit in the following healthy eating tips.
| Recommendation | Why |
|---|---|
| Choose omega-6-rich foods | Eating omega-6 fatty acids, found in corn, safflower, grapeseed, and sunflower oils, and in foods such as nuts and seeds, appears to protect against atherosclerosis and is associated with reduced heart disease risk. A diet high in omega-6 fatty acids, found in certain vegetable oils such as corn, safflower, grapeseed, and sunflower oil, and in other foods such as nuts and seeds, appears to protect against atherosclerosis. Higher dietary intake or high body levels of omega-6 fatty acids has been associated with reduced coronary heart disease risk in numerous preliminary studies, and an analysis of several controlled trials found that replacing saturated fats in the diet with omega-6 fats reduces the risk of coronary heart disease by an average of 24%. |
| Eat a high-fiber diet | Eating foods high in fiber, especially oats, psyllium seeds, fruit, and beans, may lower cholesterol and reduce the risk of coronary heart disease. A systematic review of 20 years of research evaluated the association between dietary fiber and coronary heart disease. The meta-analysis portion of this review showed that whole grain foods are associated with a coronary heart disease risk reduction of about 26%. In general, the fibers most linked to the reduction of cholesterol levels are found in oats, psyllium seeds, fruit (pectin) and beans (guar gum). An analysis of many soluble fiber trials proves that a cholesterol-lowering effect exists, but the amount the cholesterol falls is quite modest. For unknown reasons, however, diets higher in insoluble fiber (found in whole grains and vegetables and mostly unrelated to cholesterol levels) have been reported to correlate better with protection against heart disease in both men and women. Some trials have used 20 grams of additional fiber per day for several months to successfully lower cholesterol. |
| Eat more complex carbs | Choose whole grains whenever possible as a diet high in refined carbs, such as white flour, white rice, and simple sugars, appears to increase the risk of coronary heart disease, especially in overweight women. Eating a diet high in refined carbohydrates (e.g., white flour, white rice, simple sugars) appears to increase the risk of coronary heart disease, and thus of heart attacks, especially in overweight women. However, controlled trials of reducing refined carbohydrate intake to prevent heart disease have not been attempted to confirm these preliminary findings. |
| Go vegetarian | A pure vegetarian diet (no meat, poultry, dairy or eggs), combined with exercise and stress reduction, has been shown to decrease atherosclerosis. Independent of their action on serum cholesterol, foods that contain high amounts of cholesterol—mostly egg yolks—can induce atherosclerosis. It makes sense to reduce the intake of egg yolks. However, eating eggs does not increase serum cholesterol as much as eating saturated fat, and eggs may not increase serum cholesterol at all if the overall diet is low in fat. A decrease in atherosclerosis resulting from a pure vegetarian diet (no meat, poultry, dairy or eggs), combined with exercise and stress reduction, has been proven by controlled medical research. |
| Skip the salt | Eating low or moderate amounts of salt may help reduce your risk of heart disease. Preliminary evidence has suggested that excessive salt consumption is a risk factor for heart disease and death from heart disease in overweight people. Controlled trials are needed to confirm these observations. |
| Try a low-fat diet | The most important dietary changes in protecting arteries from atherosclerosis include choosing alternatives to meat and dairy, and eating foods without trans fats. The most important dietary changes in protecting arteries from atherosclerosis include avoiding meat and dairy fat and avoiding foods that contain trans fatty acids (many margarines, some vegetable oils, and many processed foods containing vegetable oils). Increasingly, the importance of avoiding trans fatty acids is being accepted by the scientific community. Leading researchers have recently begun to view the evidence linking trans fatty acids to markers for heart disease as “unequivocal.” |
| Try ALA | People who eat diets high in alpha-linolenic acid—found in canola oil and flaxseed products—have high blood levels of omega-3 fatty acids, which may protect against atherosclerosis. People who eat diets high in alpha-linolenic acid (ALA), which is found in canola oil and flaxseed products, have higher blood levels of omega-3 fatty acids than those consuming lower amounts, which may confer some protection against atherosclerosis. In 1994, researchers conducted a study in people with a history of heart disease, using what they called the “Mediterranean” diet. The diet differed significantly from what people from Mediterranean countries actually eat, in that it contained little olive oil. Instead, the diet included a special margarine high in ALA. Those people assigned to the Mediterranean diet had a remarkable 70% reduced risk of dying from heart disease compared with the control group during the first 27 months. Similar results were also confirmed after almost four years. The diet was high in beans and peas, fish, fruit, vegetables, bread, and cereals, and low in meat, dairy fat, and eggs. Although the authors believe that the high ALA content of the diet was partly responsible for the surprising outcome, other aspects of the diet may have been partly or even totally responsible for decreased death rates. Therefore, the success of the Mediterranean diet does not prove that ALA protects against heart disease. |
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 some in 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.
| Supplement | Why |
|---|---|
3 Stars Garlic 900 mg daily of a powder standardized for 0.6% allicin | Garlic has been shown to slow down the process of the arteries hardening. Aged garlic extract has been shown to prevent oxidation of LDL ("bad") cholesterol, a significant factor in atherosclerosis development. Garlic has been shown to prevent atherosclerosis in a four-year double-blind trial. The preparation used, standardized for 0.6% allicin content, provided 900 mg of garlic powder per day. The people in this trial were 50 to 80 years old, and the benefits were most notable in women. This trial points to the long-term benefits of garlic to both prevent and possibly slow the progression of atherosclerosis in people at risk. Garlic has also lowered cholesterol levels in double-blind research, though more recently, some double-blind trials have not found garlic to be effective. Some of the negative trials have flaws in their design. Nonetheless, the relationship between garlic and cholesterol-lowering is somewhat unclear. Garlic has also been shown to prevent excessive platelet adhesion (stickiness) in humans. Allicin, often considered the main active component of garlic, is not alone in this action. The constituent known as ajoene has also shown beneficial effects on platelets. Aged garlic extract, but not raw garlic, has been shown, to prevent oxidation of LDL cholesterol in humans, an event believed to be a significant factor in the development of atherosclerosis. Garlic and ginkgo also decrease excessive blood coagulation. Both have been shown in double-blind and other controlled trials to decrease the overactive coagulation of blood that may contribute to atherosclerosis. Numerous medicinal plants and plant compounds have demonstrated an ability to protect LDL cholesterol from being damaged by free radicals. Garlic, ginkgo, and guggul are of particular note in this regard. Garlic and ginkgo have been most convincingly shown to protect LDL cholesterol in humans. |
3 Stars Omega-6 Fatty Acids Follow label instructions | Though the effect has not been studied with supplements, an analysis of several controlled trials found that replacing saturated fats in the diet with omega-6 fats reduces the risk of coronary heart disease. A diet high in omega-6 fatty acids, found in certain vegetable oils such as corn, safflower, grapeseed, and sunflower oil, and in other foods such as nuts and seeds, appears to protect against atherosclerosis. Higher dietary intake or high body levels of omega-6 fatty acids has been associated with reduced coronary heart disease risk in numerous preliminary studies, and an analysis of several controlled trials found that replacing saturated fats in the diet with omega-6 fats reduces the risk of coronary heart disease by an average of 24%. |
2 Stars Fish Oil 3 to 6 grams fish oil daily, containing at least 30% omega-3 fatty acids | Fish oil may reduce risk factors for atherosclerosis and heart disease. One trial showed that people who took fish oil had a slowing of the progression of their arterial plaque and had a decrease in cardiovascular events such as heart attack and stroke. Supplementation with fish oil, rich in omega-3 fatty acids, has been associated with favorable changes in various risk factors for atherosclerosis and heart disease in some, but not all, studies. A double-blind trial showed that people with atherosclerosis who took fish oil (6 grams per day for 3 months and then 3 grams a day for 21 months) had significant slowing of progression of atherosclerotic plaques and a decrease in cardiovascular events (for example, heart attack and stroke) compared with those who did not take fish oil. These results contradict the findings of an earlier controlled trial in which fish oil supplementation for two years (6 grams per day) did not promote major favorable changes in the diameter of atherosclerotic coronary arteries. |
2 Stars Flaxseed (Hypertension) Refer to label instructions | In a double-blind trial, eating foods with milled flaxseed lowered both the systolic and diastolic blood pressure in patients with atherosclerosis of the lower extremities. In a double-blind trial, patients with atherosclerosis of the lower extremities (most of whom had high blood pressure) consumed foods that provided daily 30 g of milled flaxseed or placebo foods for 6 months. After 6 months, mean systolic blood pressure was 9.4 mm Hg lower and mean diastolic blood pressure was 6.7 mm Hg lower in the flaxseed group than in the placebo group. It is not known whether flaxseed would have a similar effect in people who do not have atherosclerosis. |
2 Stars Folic Acid Consult a qualified healthcare practitioner | Blood levels of an amino acid called homocysteine have been linked to atherosclerosis and heart disease in most research. Taking folic acid may help lower homocysteine levels. Blood levels of an amino acid called homocysteine have been linked to atherosclerosis and heart disease in most research, though uncertainty remains about whether elevated homocysteine actually causes heart disease. Although some reports have found associations between homocysteine levels and dietary factors, such as coffee and protein intakes, evidence linking specific foods to homocysteine remains preliminary. Higher blood levels of vitamin B6, vitamin B12, and folic acid are associated with low levels of homocysteine and supplementing with these vitamins lowers homocysteine levels. While several trials have consistently shown that B6, B12, and folic acid lower homocysteine, the amounts used vary from study to study. Many doctors recommend 50 mg of vitamin B6, 100–300 mcg of vitamin B12, and 500–800 mcg of folic acid. Even researchers finding only inconsistent links between homocysteine and heart disease have acknowledged that a B vitamin might offer protection against heart disease independent of the homocysteine-lowering effect. In one trial, people with normal homocysteine levels had demonstrable reversal of atherosclerosis when supplementing B vitamins (2.5 mg folic acid, 25 mg vitamin B6, and 250 mcg of vitamin B12 per day). Similar results were seen in another study. In another study, supplementing with 5 mg per day of folic acid for 18 months reversed atherosclerosis in the carotid artery (an artery that supplies the brain) in people who had one or more risk factors for cardiovascular disease. For the few cases in which vitamin B6, vitamin B12, and folic acid fail to normalize homocysteine, adding 6 grams per day of betaine (trimethylglycine) may be effective. Of these four supplements, folic acid appears to be the most important. Attempts to lower homocysteine by simply changing the diet rather than by using vitamin supplements have not been successful. |
2 Stars Horny Goat Weed 5 grams three times per day | Horny goat weed has historically been used in people with symptoms caused by hardening of the arteries. Preliminary research has suggested that it may improve markers of artery health in seniors. Horny goat weed has historically been used in people with symptoms caused by hardening of the arteries, in particular those recovering from strokes. One study of older people who had symptoms due to hardening neck arteries found that a formula in which the main ingredient was horny goat weed was superior to one not containing horny goat weed at relieving symptoms and improving the electrocardiogram findings. |
2 Stars Selenium 100 mcg daily | Some doctors recommend that people with atherosclerosis supplement with selenium, which has been shown in one study to help reduce the risk of death from heart disease. In some studies, people who consumed more selenium in their diet had a lower risk of heart disease. In one double-blind report, people who had already had one heart attack were given 100 mcg of selenium per day or placebo for six months. At the end of the trial, there were four deaths from heart disease in the placebo group but none in the selenium group; however, the number of people was too small for this difference to be statistically significant. Some doctors recommend that people with atherosclerosis supplement with 100–200 mcg of selenium per day. |
2 Stars Tocotrienols 200 mg daily | Tocotrienols are potent antioxidants that may help slow down the build-up of plaque in the arteries. Tocotrienols may offer protection against atherosclerosis by preventing oxidative damage to LDL cholesterol. In a double-blind trial in people with severe atherosclerosis of the carotid artery—the main artery supplying blood to the head—tocotrienol administration (200 mg per day) reduced the level of lipid peroxides in the blood. Moreover, people receiving tocotrienols for 12 months had significantly more protection against atherosclerosis progression, and in some cases reductions in the size of their atherosclerotic plaques, compared with those taking a placebo. |
2 Stars Vitamin B3 (Niacin) 2,000 mg per day (only under a doctor's supervision) | In a preliminary trial, doctor-supervised supplementation with extended-release niacin in combination with a cholesterol-lowering statin drug appeared to reverse atherosclerosis of the carotid arteries (the arteries that supply blood to the brain). Niacin is known to reduce serum cholesterol levels and to increase levels of HDL ("good") cholesterol. In a preliminary trial, supplementation with extended-release niacin, when used in combination with a cholesterol-lowering statin drug, appeared to reverse atherosclerosis of the carotid arteries (the arteries that supply blood to the brain). The combination of a statin drug and niacin was significantly more effective than a statin drug combined with a second cholesterol-lowering drug (ezetimibe). In addition, the statin-niacin combination was associated with a significant reduction in the number of major cardiovascular event (such as myocardial infarction or death from coronary heart disease). Niacin was used in this study in amounts up to 2,000 mg per day. These large amounts of niacin have the potential to cause side effects, including liver damage, and should be taken only with the supervision of a doctor. |
2 Stars Vitamin C 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. Vitamin C 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 Vitamin K (Vitamin K1, for coronary calcification ) 500 mcg per day of vitamin K1 | In a double-blind trial, supplementing with vitamin K1 for three years appeared to slow the rate of progression of coronary artery calcification in seniors. In a double-blind trial, supplementing with vitamin K1 for three years appeared to slow the rate of progression of coronary artery calcification in elderly people who had preexisting coronary artery calcification. Participants in that study were randomly assigned to receive a multivitamin that contained 500 mcg per day of vitamin K1 or the same multivitamin without vitamin K1. |
1 Star Betaine (Trimethylglycine) Refer to label instructions | For the few cases in which vitamin B6, vitamin B12, and folic acid fail to normalize homocysteine, adding betaine (trimethylglycine) may be effective. Regular (anhydrous) betaine is preferable to betaine hydrochloride for most people (check with a doctor). Blood levels of an amino acid called homocysteine have been linked to atherosclerosis and heart disease in most research, though uncertainty remains about whether elevated homocysteine actually causes heart disease. Although some reports have found associations between homocysteine levels and dietary factors, such as coffee and protein intakes, evidence linking specific foods to homocysteine remains preliminary. Higher blood levels of vitamin B6, vitamin B12, and folic acid are associated with low levels of homocysteine and supplementing with these vitamins lowers homocysteine levels. For the few cases in which vitamin B6, vitamin B12, and folic acid fail to normalize homocysteine, adding 6 grams per day of betaine (trimethylglycine) may be effective. Of these four supplements, folic acid appears to be the most important. Attempts to lower homocysteine by simply changing the diet rather than by using vitamin supplements have not been successful. |
1 Star Bilberry Refer to label instructions | Bilberry has been shown to prevent platelet aggregation. Turmeric’s active compound curcumin has shown potent anti-platelet activity in animal studies. It has also demonstrated this effect in preliminary human studies. In a similar vein, bilberry has been shown to prevent platelet aggregation as has peony. However, none of these three herbs has been documented to help atherosclerosis in human trials. |
1 Star Butcher’s Broom Refer to label instructions | Butcher’s broom exerts effects that protect arteries. Butcher’s broom and rosemary are not well studied as being circulatory stimulants but are traditionally reputed to have such an action that might impact atherosclerosis. While butcher’s broom is useful for various diseases of veins, it also exerts effects that are protective for arteries. |
1 Star Chondroitin Sulfate Refer to label instructions | Preliminary research shows that chondroitin sulfate may prevent atherosclerosis and may also prevent heart attacks in people who already have atherosclerosis. Preliminary research shows that chondroitin sulfate may prevent atherosclerosis in animals and humans and may also prevent heart attacks in people who already have atherosclerosis. However, further research is needed to determine the value of chondroitin sulfate supplements for preventing or treating atherosclerosis. |
1 Star Evening Primrose Oil Refer to label instructions | Taking evening primrose oil has been shown to lower cholesterol in double-blind research. Lowering cholesterol levels should in turn reduce the risk of atherosclerosis. Though low levels (2 grams per day) of evening primrose oil appear to be without action, 3–4 grams per day have lowered cholesterol in double-blind research. Lowering cholesterol levels should in turn reduce the risk of atherosclerosis. Preliminary research shows that chondroitin sulfate may prevent atherosclerosis in animals and humans and may also prevent heart attacks in people who already have atherosclerosis. However, further research is needed to determine the value of chondroitin sulfate supplements for preventing or treating atherosclerosis. |
1 Star Ginger Refer to label instructions | Supplementing with ginger may reduce platelet stickiness. The research on ginger’s ability to reduce platelet stickiness indicates that 10 grams (approximately 1 heaping teaspoon) per day is the minimum necessary amount to be effective. Lower amounts of dry ginger, as well as various levels of fresh ginger, have not been shown to affect platelets. |
1 Star Ginkgo Refer to label instructions | The herb Ginkgo biloba may reduce atherosclerosis risk by stopping platelets from sticking together too much. It also increases blood circulation to the brain, arms, and legs. Ginkgo may reduce the risk of atherosclerosis by interfering with a chemical the body sometimes makes in excess, called platelet activating factor (PAF). PAF stimulates platelets to stick together too much; ginkgo stops this from happening. Ginkgo also increases blood circulation to the brain, arms, and legs. Garlic and ginkgo also decrease excessive blood coagulation. Both have been shown in double-blind and other controlled trials to decrease the overactive coagulation of blood that may contribute to atherosclerosis. Numerous medicinal plants and plant compounds have demonstrated an ability to protect LDL cholesterol from being damaged by free radicals. Garlic, ginkgo, and guggul are of particular note in this regard. Garlic and ginkgo have been most convincingly shown to protect LDL cholesterol in humans. |
1 Star Lycopene Refer to label instructions | The carotenoid lycopene, present in high amounts in tomatoes, may help prevent atherosclerosis. The carotenoid, lycopene, has been found to be low in the blood of people with atherosclerosis, particularly if they are smokers. Although no association between atherosclerosis and blood level of any other carotenoid (e.g., beta-carotene) was found, the results of this study suggested a protective role for lycopene. Lycopene is present in high amounts in tomatoes. |
1 Star Peony Refer to label instructions | Peony has been shown to prevent platelet aggregation. Turmeric’s active compound curcumin has shown potent anti-platelet activity in animal studies. It has also demonstrated this effect in preliminary human studies. In a similar vein, bilberry has been shown to prevent platelet aggregation as has peony. However, none of these three herbs has been documented to help atherosclerosis in human trials. |
1 Star Quercetin Refer to label instructions | Quercetin, a flavonoid, protects LDL cholesterol from damage. Quercetin, a flavonoid, protects LDL cholesterol from damage. While several preliminary studies have found that eating foods high in quercetin lowers the risk of heart disease, the research on this subject is not always consistent, and some research finds no protective link. Quercetin is found in apples, onions, black tea, and as a supplement. In some studies, dietary amounts linked to protection from heart disease are as low as 35 mg per day. |
1 Star Resveratrol Refer to label instructions | Studies have found that in moderation red wine, which contains resveratrol, lowers risk of death from heart disease. Its antioxidant activity and effect on platelets leads some researchers to believe that it is the protective agent in red wine. Preliminary studies have found that people who drink red wine, which contains resveratrol, are at lower risk of death from heart disease. Because of its antioxidant activity and its effect on platelets, some researchers believe that resveratrol is the protective agent in red wine. Resveratrol research remains very preliminary, however, and as yet there is no evidence that the amounts found in supplements help prevent atherosclerosis in humans. |
1 Star Rice Protein Refer to label instructions | Though not yet proven in clinical research, animal studies suggest that rice protein–based diets result in less buildup of atherosclerotic plaque compared with animal protein–based diets. Animal studies suggest that rice protein–based diets result in less buildup of atherosclerotic plaque compared with animal protein–based diets. This effect may be due to mechanisms involving antioxidant function, cholesterol metabolism, or insulin function. Controlled human studies are needed to determine whether consuming rice protein can prevent or treat atherosclerotic disease. |
1 Star Rosemary Refer to label instructions | Rosemary is traditionally reputed to have a positive effect on atherosclerosis. Butcher’s broom and rosemary are not well studied as being circulatory stimulants but are traditionally reputed to have such an action that might impact atherosclerosis. While butcher’s broom is useful for various diseases of veins, it also exerts effects that are protective for arteries. |
1 Star Shelled Hemp Seed Refer to label instructions | Shelled hemp seed or its oil may theoretically be useful for people with atherosclerosis due to its essential fatty acid content. Though it has not been studied, shelled hemp seed or its oil may theoretically be useful for people with atherosclerosis due to its content of essential fatty acids. |
1 Star Turmeric Refer to label instructions | Turmeric’s active compound curcumin has shown potent anti-platelet activity in preliminary studies. Turmeric’s active compound curcumin has shown potent anti-platelet activity in animal studies. It has also demonstrated this effect in preliminary human studies. In a similar vein, bilberry has been shown to prevent platelet aggregation as has peony. However, none of these three herbs has been documented to help atherosclerosis in human trials. |
1 Star Vitamin B12 Refer to label instructions | Blood levels of the amino acid homocysteine have been linked to atherosclerosis and heart disease in most research. Taking vitamin B12 may help lower homocysteine levels. Blood levels of an amino acid called homocysteine have been linked to atherosclerosis and heart disease in most research, though uncertainty remains about whether elevated homocysteine actually causes heart disease. Although some reports have found associations between homocysteine levels and dietary factors, such as coffee and protein intakes, evidence linking specific foods to homocysteine remains preliminary. Higher blood levels of vitamin B6, vitamin B12, and folic acid are associated with low levels of homocysteine and supplementing with these vitamins lowers homocysteine levels. While several trials have consistently shown that B6, B12, and folic acid lower homocysteine, the amounts used vary from study to study. Many doctors recommend 50 mg of vitamin B6, 100–300 mcg of vitamin B12, and 500–800 mcg of folic acid. Even researchers finding only inconsistent links between homocysteine and heart disease have acknowledged that a B vitamin might offer protection against heart disease independent of the homocysteine-lowering effect. In one trial, people with normal homocysteine levels had demonstrable reversal of atherosclerosis when supplementing B vitamins (2.5 mg folic acid, 25 mg vitamin B6, and 250 mcg of vitamin B12 per day). Similar results were seen in another study. For the few cases in which vitamin B6, vitamin B12, and folic acid fail to normalize homocysteine, adding 6 grams per day of betaine (trimethylglycine) may be effective. Of these four supplements, folic acid appears to be the most important. Attempts to lower homocysteine by simply changing the diet rather than by using vitamin supplements have not been successful. |
1 Star Vitamin B6 Refer to label instructions | Blood levels of the amino acid homocysteine have been linked to atherosclerosis and heart disease in most research. Taking vitamin B6 may help lower homocysteine levels. Blood levels of an amino acid called homocysteine have been linked to atherosclerosis and heart disease in most research, though uncertainty remains about whether elevated homocysteine actually causes heart disease. Although some reports have found associations between homocysteine levels and dietary factors, such as coffee and protein intakes, evidence linking specific foods to homocysteine remains preliminary.

Of these four supplements, folic acid appears to be the most important. Attempts to lower homocysteine by simply changing the diet rather than by using vitamin supplements have not been successful. |
1 Star Vitamin E 100 to 200 IU daily | Vitamin E is an antioxidant that protects LDL cholesterol from oxidative damage and has been linked to heart disease prevention. Many doctors recommend supplementing with vitamin E to lower the risk of atherosclerosis and heart attacks. Vitamin E is an antioxidant that serves to protect LDL from oxidative damage and has been linked to prevention of heart disease in double-blind research. Many doctors recommend 400–800 IU of vitamin E per day to lower the risk of atherosclerosis and heart attacks. However, some leading researchers suggest taking only 100–200 IU per day, as studies that have explored the long-term effects of different supplemental levels suggest no further benefit beyond that amount, and research reporting positive effects with 400–800 IU per day have not investigated the effects of lower intakes. In a double-blind trial, people with high cholesterol who took 136 IU of natural vitamin E per day for three years had 10% less progression of atherosclerosis compared with those taking placebo. |
