Vitamins are necessary nutrients for the regulation of many different functions of the body. They are important for the formation of tissues, blood cells, genetic material, hormones and chemicals for the nervous system.

Vitamins can be catalysts or coenzymes. As catalysts, they bind with proteins to produce enzymes that, in turn, produce essential chemical reactions within the body. As coenzymes, they act as chemical carriers of one cell of the organism to another.
