Calcium Citrate is the calcium salt of citric acid, typically appearing as a white, odorless, crystalline powder that is slightly soluble in water. It is widely recognized in the pharmaceutical and food industries as a premium organic calcium compound.
Its chemical formula is often represented as Ca3(C6H5O7)2, usually found in tetrahydrate form. Compared to common inorganic calcium salts like calcium carbonate, calcium citrate is highly valued for its superior bioavailability and excellent gastrointestinal tolerance.

Product Application

1. Pharmaceutical & Nutraceutical Supplements
This is the most prevalent application. Calcium citrate is extensively used in the formulation of:
Bone Health Products: Tablets, capsules, and softgels designed to prevent osteoporosis and support bone mineral density.
Specialized Demographics: Ideal for prenatal vitamins, geriatric supplements, and pediatric formulations due to its gentle nature and ease of absorption.
2. Food Industry (Food Additive E333)
In food technology, calcium citrate serves multiple functional roles:
Nutritional Fortification: It is added to enhance the calcium content in a variety of matrices, including fruit juices, plant-based milks (soy, almond), dairy products, breakfast cereals, and infant formulas.
Functional Additive: It acts as a sequestrant (chelating agent) to improve antioxidant efficacy, a buffer to regulate acidity, and a firming agent in processed fruits and vegetables.
3. Biomedical Materials
Due to its excellent biocompatibility and biodegradability, calcium citrate is being explored in tissue engineering. It is used in the development of bone cements and scaffolds for fracture repair, where its controlled degradation releases calcium and citrate ions to stimulate osteogenesis (bone formation).
Product Customization: We accept OEM/ODM services. Customizable dosage forms (capsules, tablets, gummies, oral liquids, drops, nutritional powders, granules, etc.), packaging, logo, and formula are available according to customer requirements.

Quality Assurance: We are a source factory, utilizing internationally advanced extraction equipment and adhering to CGMP production standards.Our certified laboratory ensures product quality. Our products have obtained multiple international certifications including HALAL, FSSC 22000, ISO22000, ISO9001, and HACCP, meeting global market access standards.

Made of pure aluminum composite material, with high barrier properties, effectively isolating it from air, moisture, and light.
Completely moisture-proof, oxidation-resistant, and anti-caking, ensuring long-term preservation of powder purity.
Individually sealed and packaged; sizes can be customized in 1kg/5kg/10kg/25kg bags.
Neutral, unlabeled packaging and printing of customer logos and product information are also supported.

The independent and professional raw material storage workshop is kept at a constant temperature, dry and protected from light throughout, with ventilation, moisture control, and humidity prevention to prevent powder from absorbing moisture, clumping, deterioration, and oxidation. The workshop features zoned shelving for vertical storage, with cartons and drums stacked in separate zones to keep goods off the ground and away from moisture, acids, alkalis, odors, and sources of pollution.
