Vitamins - B, C, D and K :

A vitamin is an organic molecule that is an essential micronutrient which an organism needs in small quantities for the proper functioning of its metabolism.
Essential nutrients cannot be synthesized in the organism, either at all or not in sufficient quantities, and therefore must be obtained through the diet.
Vitamins have diverse biochemical functions:
Vitamin A acts as a regulator of cell and tissue growth and differentiation.
The Vitamin B complex functions as enzyme cofactors (coenzymes) or the precursors for them.
Vitamins C and E function as antioxidants
Vitamin D provides a hormonelike function, regulating mineral metabolism for bones and other organs.
