A vitamin is an organic molecule (or a set of molecules contiguously linked chemically, i.e. vitamers) that is an indispensable micronutrient which an organism needs in little quantities for the proper in action of its metabolism. critical nutrients cannot be synthesized in the organism, either at all or not in ample quantities, and as a result must be obtained through the diet.
