Cobalt is a trace mineral stored primarily in the liver. It acts as a catalyst that helps form vitamin B12, which is essential for making red blood cells.
Natural Food Sources
Clams, dairy products, kidney, liver, meats, oysters, some seaweed.
Cobalt works in concert with Vitamin B12 for the functioning of enzymes and production of red blood cells. It also helps form the myelin covering around the nerves.
Cobalt is found mainly in animal products, so deficiency is quite common among strict vegetarians. A deficiency in cobalt may lead to a deficiency in vitamin B12, which can lead to pernicious anemia and nervous system disorders.
Cobalt toxicity symptoms include fatigue, heart palpitations, diarrhea and numbness in fingers and toes.
