A combination dietary supplement can help control age-related macular degeneration (AMD),the leading cause of vision loss in older adults. A combination of high doses of vitamins C and E, beta carotene, and zinc delayed the development of advanced AMD in people who have intermediate-stage AMD or advanced AMD in just one eye, the Age-Related Eye Disease Study (AREDS) showed. AMD gradually destroys the macula, the part of the eye that provides sharp, central vision needed for seeing objects clearly. A followup study found that substituting lutein and zeaxanthin for beta-carotene worked better than the original formula.

Dietary supplements are not recommended for people who have early-stage AMD. If you have AMD, ask your eye care professional whether taking supplements is advisable. Keep in mind that dietary supplements can cause health problems if not used correctly or if used in large amounts, and some may interact with medications you take. Also, dietary supplements don’t appear to help cataracts, diabetic retinopathy, or glaucoma.
