Description

Calcium Glubionate is a calcium salt of glucoheptonic acid, primarily utilized as a source of bioavailable calcium. This compound is valued for its high solubility and favorable absorption profile, making it an effective mineral supplement. It is a critical ingredient for manufacturers in the pharmaceutical and nutraceutical industries, particularly for formulating oral liquid supplements, pediatric drops, and fortified food products where calcium fortification is required.

Application

• Pharmaceutical Formulations: Used as an active pharmaceutical ingredient (API) in calcium supplement syrups, pediatric drops, and effervescent tablets.
• Nutraceutical Products: A key component in dietary supplements, multivitamin/mineral complexes, and liquid nutritional drinks.
• Food & Beverage Fortification: Employed to fortify dairy alternatives, fruit juices, and infant formula with essential calcium.
• Animal Nutrition: Incorporated into feed premixes and veterinary supplements to support bone health and metabolic functions in livestock and pets.
• Clinical Nutrition: Used in medical foods and enteral nutrition products designed for patients with calcium deficiencies or malabsorption issues.

Quality Control

Our Calcium Glubionate is manufactured under strict quality management systems. Each batch is tested to ensure it meets high-purity standards suitable for pharmaceutical and food-grade applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to guarantee supply reliability and regulatory compliance.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture.
