Description

Magnesium Ascorbate Hydrate is a stable, non-acidic mineral ascorbate complex, combining the essential mineral magnesium with the antioxidant power of Vitamin C. This compound is valued for its superior bioavailability and gentle nature on the gastrointestinal system compared to ascorbic acid. It serves as a critical functional ingredient for manufacturers in the nutraceutical, pharmaceutical, and functional food and beverage industries seeking to formulate high-quality magnesium and antioxidant supplements.

Application

• Dietary Supplements & Nutraceuticals: As a key active ingredient in capsules, tablets, and powders for combined magnesium and Vitamin C supplementation.
• Pharmaceutical Formulations: Used in solid dosage forms where a buffered, non-acidic source of ascorbate is required for specific therapeutic applications.
• Functional Food & Beverage Fortification: Incorporated into health drinks, nutritional bars, and fortified foods to enhance their nutritional profile with essential minerals and antioxidants.
• Cosmeceuticals & Skincare: Employed in topical formulations for its antioxidant properties, helping to protect skin from oxidative stress and support collagen synthesis.
• Animal Nutrition (Feed Grade): Used as a nutritional additive in premium pet food and livestock feed to support overall health and immune function.
• Research & Development: Serves as a high-purity biochemical reagent in life science research and analytical laboratories.

Quality Control

Our Magnesium Ascorbate Hydrate is manufactured under strict quality management systems. We offer grades suitable for nutraceutical (FCC), pharmaceutical, and research applications. Every batch undergoes rigorous analytical testing to ensure identity, purity, and compliance with relevant specifications. A comprehensive Certificate of Analysis (COA) detailing assay, heavy metals, residual solvents, and microbiological parameters is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and easily oxidized; therefore, the container must be kept tightly sealed after opening to minimize exposure to air and moisture. For long-term storage, consider using desiccants or an inert atmosphere.
