Why the need for vitamin A (HealthyLiving)

Vitamin A is an essential fat-soluble vitamin which promotes our eyesight and helps us see in the dark. It also aids in the differentiation of cells of the skin (lining the outside of the body) and mucous membranes (linings inside of the body). Vitamin A is important as it helps the body fight off infection and sustain the immune system, but it also supports growth and remodeling of bone. If you body doesn't receive the needed vitamin A, then you could become vitamin A-deficient, which can lead to night blindness, bone problems, reduced immune system and health, anemia and unhealthy skin.
