Vitamin A Combats Macular Degeneration

Individuals who already consume healthy amounts of fruits, multicolored vegetables, leafy greens and dietary supplements may be excited to learn that a special kind of vitamin A appears to slow the onset of macular degeneration (MD).

Experts have known for years that vitamin A affects the severity of MD. For instance, the NEI found that high doses of the nutrient – 25,000 international units – combined with large amounts of zinc and cupric oxide, prevented the onset of MD in aging patients.

Also, a new study conducted at the Columbia University Medical Center found that a special form of vitamin A, which contains an isotope of hydrogen called deuterium, may clump up less in the eye’s small blood vessels. This effect could lead to better natural treatments for MD.
