Glycine, zinc salt (2:1) is a coordination compound in which one zinc ion is chelated by two glycine molecules, forming a stable five-membered ring structure. This chelation significantly improves zinc’s bioavailability and gastrointestinal tolerance compared to inorganic zinc salts. It is widely used as a source of zinc in dietary supplements, functional foods, and pharmaceutical formulations.
As a trace mineral essential for immune function, enzyme activity, and protein synthesis, zinc plays a critical role in human health. The glycine chelate form offers superior absorption and reduced gastric irritation, making it a preferred choice for formulators targeting sensitive populations or seeking to enhance mineral delivery. Glycine, zinc salt (2:1) is also utilized in animal nutrition and research applications.
