- Reliable and relatively consistent scientific data showing a substantial health benefit.
- Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
- For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.
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.

Traditional Use (May Not Be Supported by Scientific Studies)
Rhodiola has long been used in traditional medicine, primarily in Russia and Scandinavia.1 The Vikings used rhodiola to enhance physical strength and endurance, and it was commonly used by many Northern peoples to treat fatigue, poor physical endurance, nervous system disorders, and infections, and to enhance fertility. Rhodiola was included in the first Swedish Pharmacopeia, and Dioscorides, the Greek physician, reported on its use in his treatise De Materia Medica. In middle Asia, rhodiola was considered a premier treatment for colds and flu during the severe winters that occur there.
