Vitamin A benefit
Vitamin A, also known as retinol, is essential to the formation of
visual purple in the retina, which allows vision in dim light. Beta
carotene, the precursor to vitamin A found in vegetables, has
antioxidant properties, meaning it protects cells from the toxic
damage of oxidation.
