Low blood levels of vitamin C increases risk of macular degeneration by about 2 to 3 times. In rats, supplementation of vitamin C reduced retinal damage from excessive light exposure.
Astaxanthin, the pink pigment in salmon, shrimp, lobster and, yes, flamingos is yet another carotenoid that is rapidly establishing its potency for macular health maintenance and repair.
Vitamins A & E also could improve vision in macular degeneration. Because the retina is the most metabolically active tissue in the body, it requires a high level of antioxidant defense.
Taurine plays an important role in rejuvenation and regeneration of retinal cells. It is found in high concentrations in the retina, especially in the photo-receptor cells. A supplemental dose of 100 mg/day of Taurine has been recommended.
