Description

Magnesium L-Glutamate Tetrahydrate is a high-purity, organically bound magnesium salt of the amino acid L-glutamic 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 serves critical functions for manufacturers in the nutraceutical, food fortification, and cosmetic industries seeking a highly absorbable magnesium supplement.

Application

• Nutraceutical & Dietary Supplements: As a premium source of bioavailable magnesium in capsules, tablets, and powder blends.
• Food & Beverage Fortification: For magnesium enrichment in functional foods, sports nutrition products, and health drinks.
• Pharmaceutical Intermediates: Used in the synthesis of active pharmaceutical ingredients (APIs) requiring a chelated magnesium component.
• Cosmetic & Personal Care: Incorporated into skincare formulations for its potential skin-conditioning and stabilizing properties.
• Biochemical Research: As a reagent or buffer component in enzymatic studies and cell culture media.
• Animal Nutrition: As a feed additive to support magnesium supplementation in premium livestock and pet food.

Quality Control

Our Magnesium L-Glutamate 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. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, optical rotation, and loss on drying. Our quality commitment supports compliance with relevant standards for food, pharmaceutical, and nutraceutical 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). This product is hygroscopic (moisture-sensitive) and must be kept in its original, sealed packaging until use to prevent absorption of atmospheric moisture and potential caking.
