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.

Although used for long-term support of the immune system in people with depressed immune function or cancer, more research is needed to demonstrate the optimal length of time to use ligustrum.
How to Use It
Powdered, encapsulated berries, 1–3 teaspoons (5–15 grams) per day, are sometimes recommended.4 A similar amount of berries can be made into tea by adding 1/2–1 teaspoon (2–5 grams) of powdered or crushed berries to 1 cup (250 ml) of boiling water and steeping for ten to fifteen minutes. Alternatively, 3/4–1 teaspoon (3–5 ml) of tincture three times per day can be taken.
