Product Description
Introduction
Calcium citrate is a food calcium fortifier, and its absorption effect is better than that of inorganic calcium. Can be used for calcium fortification of a variety of foods, including infant formula, fruit juice, dairy products, solid beverages, sports drinks, cow milk, soy milk, health products and cereal products, etc.

AI Product Description

Calcium Citrate, often encountered in its anhydrous form or as a malate/tetrahydrate complex, represents a highly bioavailable and versatile calcium supplement widely utilized across pharmaceutical, nutraceutical, and food industries. Unlike less soluble alternatives, calcium citrate exhibits excellent absorption rates independent of gastric acidity, making it the preferred choice for individuals with low stomach acid production, such as the elderly or those taking proton pump inhibitors. The chemical composition typically involves calcium ions coordinated with citric acid residues; while "anhydrous" denotes the absence of water molecules, the tetrahydrate form contains four water molecules per formula unit, and the malate variant may refer to specific salt mixtures or impurities in commercial contexts, though pure calcium citrate is the standard active ingredient. Its molecular structure generally corresponds to Ca3(C6H5O7)2 for the anhydrous form, with a CAS number around 10098-35-4 for the trisodium salt or related variants, though specific hydrates possess distinct identifiers.
In terms of applications, this compound serves primarily as a dietary supplement to prevent and treat calcium deficiency, osteoporosis, and rickets. It plays a critical role in maintaining bone density, supporting muscle function, and facilitating nerve transmission. Beyond human health, it finds extensive use in the food industry as a firming agent, sequestrant, and acidity regulator in dairy products, baked goods, and plant-based milk alternatives. In pharmaceutical formulations, it acts as an excipient in tablets and capsules due to its stability and non-hygroscopic nature in anhydrous forms. Furthermore, its high solubility profile allows for efficient integration into liquid supplements and effervescent tablets. Safety profiles are favorable, with minimal risk of kidney stone formation compared to carbonate forms when taken at recommended dosages. As global demand for bone health solutions grows, calcium citrate remains a cornerstone ingredient, offering reliable efficacy for diverse consumer needs from pediatric growth support to geriatric maintenance, ensuring optimal physiological function through sustained mineral availability.
