A vitamin is an organic compound required as a nutrient in tiny amounts by an organism. When vitamins cannot be synthesized in sufficient quantities by an organism, they must be obtained from the diet. Thirteen vitamins are presently universally recognized. Vitamins promote health by partaking in diverse biochemical functions. Some have hormone-like functions as regulators of mineral metabolism (e.g., vitamin D), or regulators of cell and tissue growth and differentiation (e.g., some forms of vitamin A). Others function as antioxidants (e.g., vitamin E and sometimes vitamin C).

The B complex is the largest group of vitamins that function as precursors for enzyme cofactors, and help enzymes in their work as catalysts in metabolism.

The B vitamins may be necessary in order to:
 Support and increase the rate of metabolism
 Maintain healthy skin and muscle tone
 Enhance immune and nervous system function
 Promote cell growth and division, including that of the red blood cells that help prevent anemia
 Reduce the risk of pancreatic cancer – one of the most lethal forms of cancer

All B vitamins are water-soluble, and are dispersed throughout the body. Most of the B vitamins must be replenished regularly, since any excess is excreted in the urine. Several deficiency disorders may result from lack of sufficient B-vitamins, though taking large doses may produce toxic effects.

Although most varieties of vitamin B are abundantly available in several food stuffs like cereal grains, a fruit, vegetables, dairy products and fish, vitamin B12 is not available to vegans and hence needs to be supplemented vitamin B12 also called cobalamin, is a water soluble vitamin with a key role in the normal functioning of the brain and nervous system, and for the formation of blood. It is normally involved in the metabolism of every cell of the human body, especially affecting DNA synthesis and regulation, but also fatty acid synthesis and energy production. As the largest and most structurally complicated vitamin, it can be produced industrially only through bacterial fermentation-synthesis.

Vitamin B12 is provided as a supplement in many processed foods, and is also available in vitamin pill form, including multi-vitamins. Vitamin B12 can be supplemented in healthy subjects also by liquid, transdermal patch, nasal spray, or injection and is available singly or in combination with other supplements.
