Description

L-Glutamic Acid, Magnesium Salt is a stable, bioavailable complex of the amino acid L-glutamic acid and the essential mineral magnesium. This compound matters for its role as a highly absorbable source of magnesium, a critical cofactor in over 300 enzymatic reactions in the human body. Industries that need it include nutraceutical and pharmaceutical manufacturers for dietary supplements, as well as food technology for mineral fortification.

Application

• Dietary Supplements: As a premium, highly bioavailable source of magnesium for capsules, tablets, and powder formulations.
• Pharmaceutical Intermediates: Used in the synthesis of active pharmaceutical ingredients (APIs) requiring magnesium or glutamic acid moieties.
• Food & Beverage Fortification: For the nutritional enhancement of functional foods, sports nutrition products, and health beverages.
• Research & Development: As a standard or reagent in biochemical and nutritional studies.
• Animal Nutrition: Incorporated into feed premixes to support animal health and metabolic functions.
• Cosmetic Formulations: Potential use in skincare products for its role in cellular metabolism and skin barrier function.
