NOW Foods Zinc Glycinate 30 mg delivers zinc in a highly bioavailable amino acid chelate form that is significantly better absorbed and gentler on the stomach than zinc oxide or zinc sulfate. Zinc is an essential trace mineral required for over 300 enzymatic reactions in the body, playing indispensable roles in immune function, wound healing, protein synthesis, DNA repair, and normal growth and development. It is also a key component of superoxide dismutase (SOD), one of the body's most powerful antioxidant enzymes. NOW Foods uses the glycinate chelate form specifically because it is absorbed via the same pathway as amino acids, resulting in superior uptake even without food. Each softgel provides a therapeutic 30 mg dose manufactured in NOW's own GMP-certified facility and verified for potency.
