Description

Magnesium L-Aspartate is a highly bioavailable organic magnesium salt of the amino acid L-aspartic acid. This compound is valued for its superior absorption profile and stability compared to inorganic magnesium salts, making it an essential ingredient in high-performance nutritional and pharmaceutical formulations. It is primarily utilized by manufacturers in the dietary supplement, functional food and beverage, and pharmaceutical industries seeking a premium, well-tolerated magnesium source.

Application

• Dietary Supplements: A key active ingredient in magnesium capsules, tablets, and powders for supporting muscle function, nerve transmission, and bone health.
• Pharmaceutical Preparations: Used in prescription and over-the-counter medications for magnesium deficiency correction and as a therapeutic agent.
• Functional Food & Beverage Fortification: Incorporated into sports nutrition products, health drinks, and fortified foods due to its good solubility and neutral taste.
• Nutraceutical Formulations: Employed in advanced blends targeting stress relief, energy metabolism, and cardiovascular support.
• Veterinary Nutrition: Used in animal feed supplements and veterinary pharmaceuticals to promote livestock and pet health.
• Cosmeceuticals: Found in topical skincare products for its potential skin-soothing and barrier-supporting properties.

Quality Control

Our Magnesium L-Aspartate is manufactured under strict quality management systems. Each batch is tested to ensure it meets stringent specifications for identity, purity, and heavy metal content. We can supply material compliant with relevant pharmacopeial standards (such as USP/EP) and food-grade (FCC) requirements upon request. A comprehensive Certificate of Analysis (COA) documenting all test results is provided with every shipment.

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 prevent moisture absorption and caking.
