The other name of vitamin A is retinol because it produces the pigments in the retina of the eye. Vitamin A significantly promotes good vision, especially in low light. It is converted in the body, mainly from dietary beta-carotene and 3 other carotenoids. The main storage of vitamin A (i80-90%)is liver.
