Description

Magnesium Aspartate Tetrahydrate is a high-purity, organically bound magnesium salt of L-aspartic acid. This compound is valued for its superior bioavailability and stability compared to inorganic magnesium sources, making it an essential ingredient in advanced nutritional and pharmaceutical formulations. It is primarily sought by manufacturers in the nutraceutical, pharmaceutical, and food fortification industries seeking a reliable, high-quality magnesium source.

Application

• Nutraceutical & Dietary Supplements: A key active ingredient in magnesium supplements, capsules, and tablets for supporting bone health, muscle function, and energy metabolism.
• Pharmaceutical Formulations: Used in prescription and over-the-counter (OTC) medications as a magnesium source for treating deficiencies and in electrolyte balance solutions.
• Functional Food & Beverage Fortification: Incorporated into sports drinks, health bars, and fortified foods to enhance their nutritional magnesium content.
• Cosmetic & Personal Care: Utilized in skincare products for its potential skin-soothing and anti-inflammatory properties.
• Animal Nutrition (Feed Additives): Serves as a premium magnesium supplement in livestock and pet feed to promote animal health and productivity.
• Research & Development: Employed as a biochemical reagent and standard in laboratory research and analytical chemistry.

Quality Control

Our Magnesium Aspartate Tetrahydrate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards suitable for pharmaceutical and nutraceutical applications. Certificates of Analysis (COA) detailing purity, heavy metals, residual solvents, and microbiological data are provided with every shipment to guarantee traceability and compliance.

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 product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture and caking.
