Antioxidants and carotenoids linked to AMD improvements

Supplements of antioxidants and carotenoids may improve retinal health in people with age-related macular degeneration (AMD), suggesting a role beyond prevention, suggests a new study from Italy. A combination of vitamins C and E, zinc, copper, lutein, zeaxanthin, and astaxanthin was found to improve the function of the central retina among 27 people with non-advanced AMD, scientists report in the journal Ophthalmology. The daily antioxidant and carotenoid supplements provided 180 mg vitamin C, 30 mg vitamin E, 22.5 mg zinc, 1 mg copper, 10 mg lutein, 1 mg zeaxanthin, and 4 mg astaxanthin (AZYR SIFI, Catania, Italy). The researchers report that people in the antioxidant/ carotenoid supplement group showed improvements in the function of the central retina (zero to five degrees), while no improvements were observed in the peripheral retina (five to 20 degrees).
