Roll Call does not check drug interactions or assess personal safety.
A trace mineral element, essential to the body primarily as a component of vitamin B12 (cobalamin), rather than as a standalone nutrient the body uses directly.
Why it’s used
Sometimes included in mineral blends, though it is not typically taken on its own outside its role within vitamin B12.
What the evidence says
There is no established dietary requirement for cobalt itself, and no recognized RDA exists for it as a separate nutrient; its nutritional importance is understood almost entirely through its presence in vitamin B12. Evidence supporting cobalt supplementation apart from B12 is essentially absent from mainstream nutrition science.
