Vitamin B12 (cobalamin) is the only vitamin that contains cobalt, a trace mineral. It is essential to help maintain the normal functioning of all body cells, especially those of the bone marrow, gastrointestinal tract, and nervous system. B12 is also necessary for forming red blood cells. The metabolism of vitamin B12 is closely correlated with folate (folic acid) metabolism.
