Ingredient research · Zinc
Zinc is an essential mineral needed for hundreds of enzymes, DNA and protein synthesis, immune defense, wound healing, and normal growth. Supplementation corrects low zinc status and helps restore these functions; certain zinc lozenges may also modestly shorten a common cold when used early, though this benefit depends on the formulation.
