Description

Dl-Aspartic Acid Magnesium Salt Tetrahydrate is a chelated mineral complex that combines the essential amino acid aspartic acid with bioavailable magnesium. This compound is valued for its enhanced stability and bioavailability compared to inorganic magnesium salts, making it a superior choice for nutritional and pharmaceutical formulations. It serves critical roles in the nutraceutical, food fortification, and advanced pharmaceutical industries where precise mineral delivery and compatibility are required.

Application

• Dietary Supplements & Nutraceuticals: As a highly bioavailable source of magnesium for capsules, tablets, and powder blends.
• Functional Food & Beverage Fortification: For enriching products like sports nutrition drinks, meal replacements, and health bars.
• Pharmaceutical Intermediates: Used in the synthesis of advanced active pharmaceutical ingredients (APIs) requiring magnesium chelates.
• Cosmetic & Personal Care: Incorporated into skincare formulations for its potential skin-conditioning and stabilizing properties.
• Biochemical Research: Serves as a reagent in enzymatic studies and biochemical assays.
• Animal Nutrition: As a premium mineral supplement in feed for livestock and pets to support metabolic functions.

Quality Control

Our Dl-Aspartic Acid Magnesium Salt Tetrahydrate is manufactured under strict quality management systems. Each batch is tested to ensure it meets stringent specifications for identity, purity, and heavy metal content. Certificates of Analysis (COA) documenting key parameters such as assay, loss on drying, and residual solvents are available upon request. Production can be aligned with cGMP guidelines for pharmaceutical applications.

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). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture.
