Vanadium explained: what it is and safety cautions

EFSA (the European Food Safety Authority) describes vanadyl sulfate, a form intended for food supplements, as a salt that dissolves in water and contains water in its chemical structure. EFSA says it is expected to break apart into vanadyl and sulfate particles. One product we reviewed lists vanadium, and none prints its individual amount.
