Vitamin A is a fat soluble vitamin that is naturally present in many foods. Vitamin A is one of the most versatile Vitamins, with roles in such diverse functions as vision, immune defences, maintenance of body linings and skin, bone and body growth, normal cell development, and reproduction. Vitamin A helps form and maintains healthy teeth, skeletal and soft tissue, mucous membranes, and skin. Thus vitamin A and related nutrients may collectively be important in protecting against conditions related to oxidative stress, such as ageing, air pollution, arthritis, cancer, cardiovascular disease, cataracts, diabetes mellitus and infection. Vitamin A is essential to normal growth. Vitamin A is necessary for cell growth and cell differentiation - the process by which a cell changes its structure and develops specific functions. It plays important roles in reproduction, bone growth and tooth development.
