Description

Magnesium Citrate, Dibasic Hydrate is a high-purity, organically-bound magnesium salt of citric acid, widely recognized for its superior bioavailability and stability. This compound is essential for formulating high-quality nutritional supplements and pharmaceutical products where consistent mineral delivery is critical. It serves as a key functional ingredient for manufacturers in the nutraceutical, food & beverage, and pharmaceutical industries seeking a reliable magnesium source.

Application

• Dietary Supplements & Nutraceuticals: A primary magnesium source in capsules, tablets, and powder blends for bone health, muscle function, and electrolyte balance.
• Pharmaceutical Formulations: Used as an active pharmaceutical ingredient (API) in magnesium deficiency treatments and as an excipient in effervescent and controlled-release tablets.
• Food & Beverage Fortification: An effective mineral fortifier for sports drinks, functional waters, and health-focused food products to enhance nutritional value.
• Cosmetic & Personal Care: Incorporated into skincare products for its soothing and anti-inflammatory properties, and in oral care for dental health formulations.
• Industrial Applications: Acts as a buffering agent, sequestrant, or stabilizer in various chemical and technical processes.

Quality Control

Our Magnesium Citrate, Dibasic Hydrate is manufactured under strict quality management systems. We offer grades compliant with FCC (Food Chemicals Codex) and USP (United States Pharmacopeia) standards, ensuring suitability for food, nutraceutical, and pharmaceutical applications. Every batch undergoes rigorous analytical testing, and a comprehensive Certificate of Analysis (COA) documenting purity, identity, and safety parameters is available upon request.

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