Vitamin Formulas are based on proven research in the most respected medical publications, including the National Eye Institute’s Age-Related Eye Disease Study (AREDS), Age-Related Eye Disease Study 2 (AREDS2), the Lutein Antioxidant Supplement Trial (LAST) and others. Flimsy research or mere opinions are not the method used in the creation of our supplements.
AREDS is an acronym that stands for Age-Related Eye Disease Study. The study was completed in completed in October 2001 by the National Eye Institute, part of the United States National Institutes of Health. Institutes of Health. Results from the AREDS showed that high levels of antioxidants and zinc significantly reduce the risk of advanced age-related macular degeneration (AMD) and its associated vision loss. These same nutrients had no significant effect on the development or progression of cataract.
AREDS2 and LAST
While AREDS was the first study demonstrating benefit against this retinal eye disease, it failed to demonstrate improvement in vision. AREDS2 (AREDS 2), the second major study performed by the U.S. National Eye Institute, showed that lutein and zeaxanthin were more effective than beta-carotene and that daily zinc levels of 25 mg and 80 mg were not significantly different in benefit. Other studies, including the Lutein Antioxidant Supplement Trial, have demonstrated vision improvement. Finally, work involving both Lutein and Zeaxanthin, molecules known as carotenoids, have shown not only vision improvement but also a healthier macular appearance and improvement in Macular Pigment Optical Density (MPOD).
