Description

L-Aspartic Acid Magnesium Salt is a chelated mineral complex combining the essential amino acid L-aspartate with bioavailable magnesium. This compound matters for its superior absorption profile and stability compared to inorganic magnesium salts, making it an effective and gentle source of magnesium. It is primarily needed by manufacturers in the nutraceutical, pharmaceutical, and functional food industries seeking to formulate high-quality magnesium supplements and fortified products.

Application

• Dietary Supplements & Nutraceuticals: As a highly bioavailable source of magnesium in capsules, tablets, and powder formulations for supporting muscle function, nerve transmission, and bone health.
• Pharmaceutical Intermediates: Used in the synthesis of active pharmaceutical ingredients (APIs) where a chelated magnesium source is required.
• Functional Food & Beverage Fortification: For enriching sports nutrition products, health drinks, and meal replacements with a well-tolerated form of magnesium.
• Animal Nutrition (Feed Additives): Incorporated into premixes to provide essential magnesium for livestock, poultry, and pet health.
• Cosmetic & Personal Care: Potential use in skincare formulations for its skin-conditioning properties and role in cellular processes.
• Biochemical Research: Serves as a reagent in enzymatic studies and biochemical assays requiring magnesium aspartate.

Quality Control

Our L-Aspartic Acid Magnesium Salt is produced under a strict quality management system. Each batch undergoes rigorous testing to ensure it meets specifications for identity, purity, and heavy metal content. We can supply material compliant with relevant standards for dietary supplements. Certificates of Analysis (COA) documenting purity, assay, and residual solvents are available for every shipment upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
