Cobalt is a trace mineral that is an integral part of vitamin B-12. As such, the functions of cobalt are essentially the same as B-12.1

Cobalt is primarily stored in the liver with decreasing amounts found in the spleen, kidneys and pancreas.

Blood cobalt concentrations typically range from 80 micrograms per milliliter (mcg/ml) to 300 mcg/ml.

Cobalt activates a number of enzymes within the body. It plays a key role in the proper functioning and promotes the formation and maintenance of red blood cells in addition to all other cells. 1

Cobalt can replace zinc and manganese in the activation of several enzymes.
