152 Zinc is a mineral essential for formation of superoxide dismutase, one of the body's most important free radical scavengers and one that cannot be directly supplemented. Zinc also promotes wound healing, immune function, taste sensitivity, protein synthesis, insulin production, and reproduction including organ development and sperm motility.
Supplemental zinc can inhibit the absorption and availability of copper.
Chronic ingestion of more than 100 mg of zinc daily may be toxic.
