A variety of vitamins and minerals are essential to eye health. Vitamin E, in particular, has been shown in studies to reduce the risk of Age Related Macular Degeneration (AMD) by 25%. This is significant for a vitamin that is affordable and easy to take. The study showed that 400IU was the recommended dosage to promote eye health. While this is a significantly higher dosage than the FDA recommended 4mg for men and 3mg for woman, taking less than 540 mg of Vitamin E a day should not be harmful. However, those with heart disease or diabetes should consult there doctor before taking vitamin E. We recommend that you talk to your eye doctor before starting a Vitamin E regimen.
