Vitamin B6 (Pyridoxine)
Vitamin B6, or pyridoxine, is an essential water-soluble vitamin that plays a role in many metabolic functions, including carbohydrate, fat and protein metabolism, as well as red blood cell formation and nervous system function. It exists in several forms, including pyridoxine, pyridoxal and pyridoxamine, which are required by the body because the body cannot produce them.
