Study: Lutein and Prevention of Macular Degeneration

1994 Study; Dr. Johanna Seddon of Harvard University published a study in the Journal of the American Medical Association that examined the effect of consumption of specific carotenoids on AMD prevention. The results of the study found that the highest correlation of disease prevention was associated with an intake of 6 mg per day of lutein, which led to a 57% decrease in the risk of contracting AMD. Therefore, lutein is the key carotenoid for providing the proper amount of lutein and zeaxanthin.
