What Is Cobalt?

Cobalt is an ultratrace mineral and an essential macronutrient. But it’s a relatively rare element. An adult human body contains about 1 mg of cobalt, 85% of which is in the form of vitamin B12.

It’s the cobalamin that is measured in foods. Other cobalt content in foods is not well documented.

Cobalamin deficiency is very common among vegetarians, vegans, and other plant-eating populations because the easiest way to consume cobalt is from animal sources.
