A. Vitamin A helps maintain healthy skin, eyesight, bone growth and tooth development; enhances our immune system so we are better able to fight infection; and may reduce the risk of lung and oral cancers. Vitamin A is a fat-soluble vitamin composed of compounds called carotenoids and retinoids (retinal). Carotenoids, or beta carotene, are converted to vitamin A in the body. Lack of vitamin A could result in night blindness, increased risk of infections, fatigue and gum and teeth problems. Too much vitamin A could result in liver damage, hair loss, headaches, loss of appetite and possible birth defects. Excessive amounts of beta carotene can cause skin to appear orange, especially on the palms of the hands.
