Cobalt is a trace element mineral whose main function is in vitamin B12, although there are some cobalt-dependent enzymes. There is no evidence of cobalt deficiency in human beings, and no evidence on which to base estimates of requirements for inorganic cobalt.obalt is a trace element mineral whose main function is in vitamin B12, although there are some cobalt-dependent enzymes.

When it was recognized that cobalt was 4.4% of the molecular weight of vitamin B12 and that rumen bacteria could efficiently synthesize B12, these differences started to make sense. Cobalt deficiency in ruminants leads to a vitamin B12 deficiency that is corrected with cobalt supplementation.
