calcium citrate tribasic tetrahydrate

Calcium Citrate Tribasic Tetrahydrate (Tricalcium Citrate) 98% is an inorganic calcium salt of citric acid with the chemical formula Ca₃(C₆H₅O₇)₂·4H₂O. It is typically supplied as a white, odorless, fine crystalline powder with good stability and flow characteristics. The product contains approximately 98% active calcium citrate, with four molecules of water of crystallization contributing to its physical structure and stability.

This compound is slightly soluble in water but more readily soluble in acidic media, making it highly suitable for nutritional and pharmaceutical applications. It is widely used as a calcium supplement due to its high bioavailability and easy absorption, even in individuals with low stomach acid.

In the food industry, calcium citrate acts as a firming agent, preservative, and acidity regulator, while in pharmaceuticals it is used in tablets and capsules as an active ingredient or excipient. It is also utilized in fortified foods, beverages, and dietary supplements.

Calcium citrate tribasic tetrahydrate is chemically stable, non-toxic, and safe under normal handling conditions. It should be stored in a cool, dry place in well-sealed containers to prevent moisture variation and maintain product quality.
