supplements to help prevent or slow age-related macular degeneration (AMD)

Patients are focusing on supplements to help prevent or slow age-related macular degeneration (AMD).

High doses of beta-carotene, vitamin C, vitamin E, and zinc in a specific product called PreserVision slows progression and loss of visual acuity in people who already have macular degeneration.

But now there are concerns about whether these doses are safe. High doses of beta-carotene seem to increase the risk of lung cancer in smokers...and high doses of vitamin E might increase mortality.
