Description

Magnesium Gluconate is a highly bioavailable organic salt of magnesium, a vital mineral for numerous physiological processes. This compound is prized for its superior absorption and gastrointestinal tolerance compared to inorganic magnesium salts, making it an essential ingredient for high-quality nutritional and pharmaceutical formulations. It serves as a critical raw material for manufacturers in the dietary supplement, pharmaceutical, food fortification, and personal care industries seeking a reliable and effective magnesium source.

Application

• Dietary Supplements & Nutraceuticals: As a premium magnesium source in capsules, tablets, powders, and liquid formulations to support bone health, muscle function, and energy metabolism.
• Pharmaceutical Preparations: Used in OTC and prescription medications for magnesium deficiency treatment and as an excipient in various solid dosage forms.
• Food & Beverage Fortification: Incorporated into functional foods, sports nutrition products, and beverages to enhance their nutritional profile.
• Cosmetics & Personal Care: Utilized in skincare products for its potential skin-soothing and anti-inflammatory properties.
• Animal Nutrition (Feed Grade): As a nutritional additive in premixes and feed to support livestock and pet health.
• Research & Development: Serves as a key reagent and standard in biochemical and pharmaceutical research laboratories.

Quality Control

Our Magnesium Gluconate is manufactured under strict quality management systems. We offer grades compliant with relevant pharmacopeial standards, including USP and EP, as well as FCC for food applications. Every batch undergoes rigorous analytical testing to ensure identity, purity, and safety. A comprehensive Certificate of Analysis (COA) detailing assay, heavy metals, microbial limits, and other critical parameters is provided with each shipment to guarantee traceability and regulatory compliance.

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). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
