Zinc Immune function and oxidative stress regulator Though not an antioxidant itself, zinc plays multiple roles in the body's antioxidant defense system: Acts as a cofactor for superoxide dismutase, a primary antioxidant enzyme Stabilizes cell membranes, reducing susceptibility to oxidative damage Induces metallothionein, which scavenges hydroxyl radicals Competes with iron and copper for binding sites, potentially reducing free radical production Zinc supplementation (recommended intake: 8-11 mg/day for adults) has been shown to reduce oxidative stress markers, particularly in zinc-deficient individuals
