Vitamins are essential biological molecules that must be taken, generally in small quantities, with the diet because the organisms are not able to synthesize. The requirement for a certain vitamin depends on the type of organism and not all organizations need all the vitamins.

Vitamins are divided into:

Water-soluble vitamins do not accumulate in the body and therefore must be taken daily with food. This includes all the group B vitamins and vitamin C.

Fat-soluble vitamins are absorbed along with dietary fats and accumulated in the liver. The deficiency manifests then following a failure assumption for long times. They include vitamin A, D, E, and vitamin K.
