What Are "Star" Ratings?
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.

About this treatment
How to Use It
People showing protection from macular degeneration have been reported to have eaten about 6 mg of lutein per day from food. Lutein, in supplemental form, should be taken with fat-containing food to improve absorption.
Where to Find It
Spinach, kale, collard greens, romaine lettuce, leeks, peas, and egg yolks are good sources of lutein.
Possible Deficiencies
While a deficiency has not been identified, people who eat more lutein-containing foods appear to be at lower risk of macular degeneration. One study found that adults with the highest dietary intake of lutein had a 57% decreased risk of macular degeneration compared with those people with the lowest intake, and of the carotenoids, lutein and zeaxanthin are most strongly associated with this protection. In a preliminary study, a similar link was suggested between low dietary lutein and increased risk of cataracts.
