Description

L-Glutamic Acid Magnesium Salt Trihydrate is a high-purity, organically bound magnesium compound derived from the amino acid L-glutamic acid. This specialized chelate offers superior bioavailability and stability compared to inorganic magnesium salts, making it a critical ingredient for advanced nutritional and pharmaceutical formulations. It is primarily sought by manufacturers in the nutraceutical, pharmaceutical, and high-end food supplement industries seeking a highly absorbable magnesium source with excellent compatibility.

Application

• Nutraceutical & Dietary Supplements: As a premium, bioavailable source of magnesium in capsules, tablets, and powdered drink mixes for supporting nerve function, muscle health, and energy metabolism.
• Pharmaceutical Formulations: Used in the development of magnesium replacement therapies, electrolyte balance solutions, and specialized mineral supplements where high purity and predictable absorption are paramount.
• Functional Food & Beverage Fortification: Incorporated into health-focused foods, sports nutrition products, and fortified beverages due to its good solubility and neutral flavor profile compared to other magnesium salts.
• Research & Biochemical Applications: Serves as a reagent or standard in biochemical research, enzymatic studies, and cell culture media requiring a defined source of magnesium ions.
• Cosmetic & Personal Care: Potential use in topical formulations for skin conditioning, where magnesium plays a role in cellular processes.
