Nutrition and AMD

There's no substitute for the quality of life good vision offers. Adding certain nutrients to your diet every day - either through foods or supplements - can help save your vision. Researchers have linked eye-friendly nutrients such as lutein/zeaxanthin, vitamin C, vitamin E, and zinc to reducing the risk of certain eye diseases, including macular degeneration.

Lutein and Zeaxanthin—10 mg Lutein, 2 mg Zeaxanthin per day to slow AMD progression

Lutein (LOO-teen) and zeaxanthin are important nutrients found in green leafy vegetables as well as other foods such as eggs. Many studies have shown that lutein and zeaxanthin reduce the risk of chronic eye diseases, including age-related macular degeneration (AMD).

Much evidence supports the role of lutein and zeaxanthin in reducing the risk of AMD. In fact, The National Eye Institute presently is conducting a second large human clinical trial, Age-Related Eye Disease Study (AREDS2), to confirm whether supplements containing 10 mg a day of lutein and 2 mg of zeaxanthin per day affect the risk of developing AMD. Beyond reducing the risk of developing eye disease, separate studies have shown that lutein and zeaxanthin improve visual performance in AMD patients.

Vitamin CNeed 500 mg per day to slow AMD progression

Scientific evidence suggests vitamin C , when taken in combination with other essential nutrients, can slow the progression of age-related macular degeneration (AMD) and visual acuity loss. The Age-Related Eye Disease Study (AREDS), sponsored by the National Eye Institute, was a landmark study that established AMD as a 'nutrition-responsive disorder.' The study showed that a 500 mg/day intake of vitamin C, taken with antioxidants beta-carotene, vitamin E and zinc supplementation, slows the progression of advanced age-related macular degeneration by about 25 percent. Emerging science, consisting of the AREDS results and seven smaller studies, have confirmed these results.

Vitamin E—Need 400 mg per day to slow AMD progression

The study showed that a 400 IU/day intake of vitamin E, taken with antioxidants beta-carotene, vitamin C and zinc supplementation, slows the progression of advanced age-related macular degeneration (AMD) by about 25 percent in individuals at high-risk for the disease.

Zinc—Need 40 to 80 mg daily to slow AMD progression

The Age-Related Eye Disease Study (AREDS), sponsored by the National Eye Institute, was a landmark study that established AMD as a 'nutrition-responsive disorder.' The study showed that a 40-80 mg/day intake of zinc, taken with antioxidants beta-carotene, vitamin E and vitamin C, slows the progression of advanced age-related macular degeneration by about 25 percent and visual acuity loss by 19 percent in individuals at high-risk for the disease. Higher levels of zinc may interfere with copper absorption, which is why the AREDS study also included a copper supplement.
