§§§

A vitamin is an organic chemical compound or related set of compounds and a vital nutrient that an organism requires in limited amounts and which the organism cannot synthesize in sufficient quantities so it must be obtained through the diet. This definition of vitamin is conditional so that the list of vitamins is different for different organisms. For example vitamin C is not a vitamin for many animals.
