Heavy Metals

Cobalt

A naturally occurring metal element used industrially and as a dietary trace mineral. While cobalt is essential in small amounts as a component of vitamin B12, excessive exposure, particularly by inhalation or skin contact in industrial settings, can pose health risks including respiratory and skin sensitization, and potential carcinogenicity. Cobalt metal is not a food ingredient and poses toxicity risks when used inappropriately.
