Abstract:Magnesium glycinate, a highly bioavailable chelated mineral form combining magnesium ions with Glycine amino acids, represents a significant advancement in nutritional supplementation addressing the absorption limitations and gastrointestinal challenges of traditional magnesium salts. This comprehensive analysis examines the molecular characteristics, physiological benefits, and diverse applications of this premium magnesium source across dietary supplements, functional foods, clinical therapeutics, and sports nutrition.

Magnesium glycinate distinguishes itself from conventional magnesium compounds through its unique chelated molecular architecture, wherein magnesium ions coordinate with glycine molecules to form stable, organic complexes. This chelation process fundamentally transforms the mineral's physiological behavior, protecting magnesium from competitive inhibition by calcium, phosphorus, and other dietary antagonists that impair absorption of inorganic magnesium forms. The resulting molecular stability ensures that magnesium reaches intestinal absorption sites in bioaccessible form, independent of gastric pH conditions or meal composition timing.

The absorption pathway for magnesium glycinate leverages amino acid transport systems rather than relying solely on passive paracellular diffusion or transient receptor potential melastatin channels utilized by ionic magnesium. Glycine-chelated magnesium utilizes intestinal peptide transporters, specifically the proton-coupled oligopeptide transporter PEPT1, which facilitates efficient uptake across the brush border membrane of enterocytes. This transport mechanism achieves absorption rates significantly exceeding those of magnesium oxide or magnesium sulfate, particularly in populations with compromised gastric acid production, reduced intestinal surface area, or inflammatory conditions affecting nutrient assimilation.
