How it works

Zinc is an essential mineral that supports immune function, protein synthesis, and DNA repair. Strong evidence supports its use for reducing the duration of the common cold and correcting deficiencies that impact testosterone and skin health.

Zinc acts as a cofactor for over 300 enzymes and modulates immune cell activity, specifically T-cell and natural killer cell function.
