Zinc Glycinate Liquid is a great-tasting mineral formula that provides zinc in the bioavailable form of zinc bisglycinate. Zinc is an important trace element in the body. It plays a key role in maintaining immune health by stimulating the production of immune cells, regulating natural killer cell activity and mediating cytokine production. Clinical research has demonstrated that daily supplementation with zinc helps to maintain immune function in adults and adolescents, as well as in the airways of children. Zinc also has a long history of use in dermatological health. It helps to maintain immune function in the skin, while promoting collagen synthesis to help maintain skin structure.  Additionally, zinc has a role in maintaining hair and nail health, and maintains bone health by regulating bone formation and resorption.  This mineral is also involved in a key buffer system that helps to maintain normal acid-base balance.  Zinc Glycinate Liquid provides a bioavailable source of zinc to help meet daily zinc requirements. In one randomized crossover trial, zinc bisglycinate was demonstrated to have 43% higher bioavailability than zinc gluconate.
