Calcium Glycinate is a mineral amino acid chelate in which calcium ions are bound to glycine molecules, forming a stable complex that enhances intestinal absorption. Unlike inorganic calcium sources such as calcium carbonate, the chelated form does not require stomach acid for solubilization, making it gentler on the digestive system. The glycine ligand facilitates absorption through amino acid transport pathways in the small intestine, resulting in higher bioavailability. Calcium Glycinate provides approximately 20% elemental calcium by weight and is well-tolerated with minimal gastrointestinal side effects.
