What Does Zinc (Glycinate Chelate) Do?

Zinc supports normal immune function and normal cognitive performance, while also supporting antioxidant defences as part of daily physiological processes. The chelated form may help support uptake and utilisation in the body, matching routine health needs and everyday vitality.
