Calcium Citrate Manufacturer, Exporter and Supplier

Calcium Citrate Overview

Calcium Citrate is a highly bioavailable calcium salt widely used as an active ingredient in pharmaceutical, nutraceutical, and food formulations to support bone health and calcium supplementation. Known for its excellent solubility and superior absorption, even in individuals with low stomach acid, Calcium Citrate plays a vital role in maintaining healthy bones, teeth, muscle function, and nerve transmission. It is scientifically recognized for effectively helping prevent and treat calcium deficiency while supporting overall skeletal health with excellent gastrointestinal tolerability.

Calcium Citrate Manufacturing process

Calcium Citrate is manufactured through a carefully controlled neutralization and crystallization process to ensure high purity, consistent quality, and compliance with pharmaceutical and food-grade standards.

Step 1: Raw Material Selection

High-quality calcium sources and purified citric acid are selected and tested to ensure compliance with predefined quality specifications.

Step 2: Neutralization Reaction

Citric acid is gradually reacted with the calcium source under controlled temperature, pH, and agitation conditions to form Calcium Citrate.

Step 3: Purification

The reaction mixture is purified to remove any unreacted materials and process-related impurities, ensuring the desired product quality.

Step 4: Filtration

The purified slurry is filtered to separate the Calcium Citrate crystals from the liquid phase.

Step 5: Washing

The filtered crystals are thoroughly washed with purified water to remove residual impurities and soluble salts.

Step 6: Drying

The washed Calcium Citrate is dried under controlled temperature conditions to achieve the required moisture content without affecting product quality.

Calcium Citrate Applications

Pharmaceutical Applications

Calcium Source in Pharmaceutical Formulations

Suitable pharmaceutical grades of Calcium Citrate may be used as a source of calcium in selected pharmaceutical formulations. Manufacturers can incorporate it into suitable dosage forms where calcium supplementation is required, subject to formulation and regulatory requirements.
