Description

Dl-Aspartic Acid Hemimagnesium Salt is a high-purity, organically bound magnesium compound derived from the amino acid aspartic acid. This specialized salt is valued for its enhanced bioavailability and stability compared to inorganic magnesium sources, making it an effective mineral supplement. It is primarily utilized in the pharmaceutical and nutraceutical industries for the formulation of magnesium supplements, functional foods, and specialized electrolyte solutions.

Application

• Pharmaceutical Intermediates & APIs: Used as a key ingredient in the synthesis of active pharmaceutical ingredients (APIs) and as a direct source of bioavailable magnesium in mineral supplement tablets and capsules.
• Nutraceuticals & Dietary Supplements: Incorporated into high-end dietary supplements, multivitamin complexes, and sports nutrition products for efficient magnesium delivery.
• Functional Food & Beverage Fortification: Employed to fortify health drinks, meal replacement shakes, and functional food products with a well-tolerated and soluble form of magnesium.
• Biochemical Research & Cell Culture: Serves as a defined source of magnesium ions in biochemical research, enzymatic studies, and specialized cell culture media formulations.
• Veterinary Nutrition: Applied in the production of mineral premixes and specialized feeds for livestock and companion animals to support bone health and metabolic functions.
