People who get the most lutein and zeaxanthin in their diets tend to have lower rates of macular degeneration — the leading cause of blindness in developed countries. Supplements with lutein have been shown to improve vision in people with age-related macular degeneration. But our tests showed one supplement to have only 45% of one of these ingredients. What's more, the amount of lutein in the products tested varied by as much as 6-fold. If you're not getting enough, you may not be getting the maximum benefit.
In this Review, you'll get ConsumerLab's test results for eighteen milk thistle supplements as well as information about five products similar to those that passed testing. You'll also learn the amount of lutein that seems to help and how you can get it from foods and supplements.
