Vitamins

Vitamins are essential chemicals needed in small amounts for smooth metabolic functions within a given organism. Some vitamins cannot be synthesized by the body and therefore must be obtained in the diet. Vitamins perform a multitude of varied functions, from acting as coenzymes and antioxidants, to regulating tissue growth and differentiation. In humans, there are 13 essential vitamins – A (retinoids and carotene), B1 (Thiamine), B2 (Riboflavin), B3 (Niacin), B5 (Pantothenic acid), B6 (Pyridoxine), B7 (Biotin), B9 (Folic acid), B12 (Cobalamin), C (Ascorbic acid), D (Calciferol), E (Tocopherol), and K (phylloquinone and menaquinone).
