Zinc Bisglycinate

Zinc bisglycinate is a chelated form of the essential trace mineral zinc, where zinc ions are bound to two molecules of the amino acid glycine. This chelation process is designed to enhance the absorption and bioavailability of zinc in the body compared to other forms, such as zinc oxide or zinc gluconate (PubChem). As an essential mineral, zinc plays a crucial role in numerous physiological processes, including immune function, cell division, wound healing, protein synthesis, and DNA synthesis (National Institutes of Health Office of Dietary Supplements). It is a cofactor for over 300 enzymes involved in metabolic reactions. Dietary sources of zinc include red meat, poultry, seafood (especially oysters), dairy products, nuts, legumes, and whole grains. Despite its presence in various foods, zinc deficiency can occur, particularly in individuals with certain dietary restrictions (e.g., vegetarians, vegans), gastrointestinal disorders, or those with increased needs, such as pregnant women and children (MedlinePlus). Zinc bisglycinate is commonly used as a dietary supplement to address or prevent zinc deficiency and to support overall health.
