GLOSSARY

Cobalt Toxicity is harm from inappropriate exposure to the element or its compounds, with form, route, amount and duration determining risk.

Cobalt has an established role within vitamin B12, but humans do not synthesize the needed cobalamin by eating cobalt salts. Free cobalt is therefore not a vitamin replacement or an energy aid. Excess exposure to some cobalt compounds can affect the heart, thyroid or other organs. Vitamin requirements and safety must be distinguished from free-element toxicity and industrial exposure rather than treating all cobalt forms as interchangeable.

Essentiality does not make any amount harmless. Chemical form, dose, duration, kidney or liver function and medicines affect risk. High intake and established toxicity are not identical, but overlapping supplements should be identified before symptoms occur. A therapeutic dose for a defined condition is not a routine recommendation for every athlete, and a larger intake does not necessarily produce a better outcome.

The mass of a salt or supplement compound is not its elemental mass. Reliable labels specify the element per serving, and the number of capsules per serving matters. Bone, sleep and multimineral products or sports drinks can overlap. Align units and serving amounts before summing, so compound weight or package size is not mistaken for actual elemental intake.
