Cobalt poisoning is intoxication caused by excessive levels of cobalt in the body. Cobalt is an essential element for health in animals in minute amounts as a component of vitamin B 12 . A deficiency of cobalt, which is very rare, is also potentially lethal, leading to pernicious anemia .
In humans most cobalt is found in Vitamin B12.A cobalt atom is visible in the center in this diagram. Cobalt is essential to the metabolism of all animals.It is a key constituent of cobalamin, also known as vitamin B 12, the primary biological reservoir of cobalt as an ultratrace element.
selenium deficiency / selenosis: Cobalt: none NE; NE: Cobalt is available for use by animals only after having been processed into complex molecules (e.g., vitamin B 12) by bacteria. Humans contain only milligrams of cobalt in these cofactors. A deficiency of cobalt leads to pernicious anemia.
