Vitamins are organic molecules that are necessary for normal metabolism in animals, but either are not synthesized in the body or are synthesized in inadequate quantities. Consequently, vitamins must be obtained from the diet. Most vitamins function as coenzymes or cofactors. Deficiency states are recognized for all vitamins, and in many cases, excessive intake also leads to disease.
