Introduction:

All the vitamins play a considerable role in growth and metabolism of the body. Vitamins are mostly obtained from food. There are fourteen vitamins that are considered essential for normal body growth. There are two types of vitamins: water-soluble vitamins, which form some portions of coenzymes, and fat-soluble vitamins, which do not, in general, work as coenzymes. Fat-soluble vitamins are vitamin A, D, E, and K. Water-soluble vitamins are coenzymes A, NAD⁺, and FAD. The body requires vitamins in small amounts but a deficiency of any vitamin can severely affect the body.
