Dr. Mercola Zinc Plus Selenium - 90 Capsules

What it's for Immune support; Antioxidant support; Cellular health; Nutritional replenishment Who it may fit Adults seeking convenient daily intake of zinc and selenium or those with diets low in mineral-rich foods. Key actives per serving Zinc (from Zinc Bisglycinate Chelate): 15 mg (136% DV) Selenium [from Selenium Yeast (Saccharomyces cerevisiae)]: 200 mcg (364% DV) Copper (from Copper Bisglycinate Chelate): 0.25 mg (28% DV) How to take Adults take 1 capsule once daily with a meal; taking with food may improve tolerance and absorption for mineral chelates. Ingredients explained Zinc (from Zinc Bisglycinate Chelate) Zinc acts as a cofactor for many enzymes involved in antioxidant defenses, immune cell function, and protein and DNA synthesis. Caution: Take with food if stomach upset occurs, and avoid taking at the same time as high-iron or high-calcium supplements as they may compete for absorption. Selenium [from Selenium Yeast (Saccharomyces cerevisiae)] Selenium supports antioxidant activity by being incorporated into selenoproteins like glutathione peroxidases that help neutralize free radicals. Caution: High intakes from multiple selenium sources may cause unwanted effects; keep total daily selenium within recommended limits. Copper (from Copper Bisglycinate Chelate) Copper functions as a cofactor for enzymes involved in energy production, connective tissue formation, and antioxidant defenses such as superoxide dismutase. Caution: Do not combine with additional high-dose copper supplements unless directed, as excessive copper may cause gastrointestinal discomfort. How they work together Zinc and selenium both contribute to antioxidant processes through different enzyme systems, offering complementary support for cellular protection. Copper adds enzymatic cofactor activity relevant to energy metabolism and antioxidant enzymes, balancing mineral interactions in a zinc-forward formula. Safety and tips Label Warning: If you are pregnant, nursing, taking medication, or have a medical condition, consult a physician before use. Who should be cautious: People with thyroid concerns or taking thyroid medications may want to be cautious with selenium. Those with copper metabolism issues may wish to discuss copper content with a healthcare provider.
