Description

Magnesium Citrate Hydrate, Mg Ca 16% (Dry Wt.) CAS NO 120156-45-8 is a high-purity, organically bound magnesium salt derived from citric acid, offering superior bioavailability compared to inorganic magnesium sources. This compound is critical for applications requiring a highly soluble and bioavailable form of magnesium, essential for numerous biochemical and industrial processes. It is primarily sought by manufacturers in the pharmaceutical, nutraceutical, and food & beverage industries for its role as a premium mineral supplement and functional ingredient.

Application

• Pharmaceutical & Nutraceutical Formulations: Used as a key active ingredient in magnesium supplements, tablets, capsules, and effervescent powders to address magnesium deficiency and support bone health, muscle function, and energy metabolism.
• Food & Beverage Fortification: Serves as a nutritional fortificant in functional foods, sports drinks, dairy alternatives, and infant formula to enhance magnesium content.
• Dietary Supplements: A preferred source of magnesium in high-quality dietary supplements due to its excellent absorption profile and gentle effect on the digestive system.
• Cosmetic & Personal Care: Incorporated into skincare products for its potential skin-soothing and anti-inflammatory properties.
• Laboratory & Research: Utilized as a reagent or buffer component in biochemical research and diagnostic kit manufacturing.
• Industrial Applications: Acts as a catalyst or stabilizer in certain chemical synthesis processes and as a component in specialty fertilizers.

Quality Control

Our Magnesium Citrate Hydrate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets specifications for identity, purity, and heavy metal content. We can supply material compliant with relevant standards such as USP-NF, FCC, or Ph. Eur. upon request. A comprehensive Certificate of Analysis (COA) documenting assay, loss on drying, and impurity profiles 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 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, which can lead to caking or degradation.
