Calcium citrate

Description:

Calcium citrate is a calcium salt of citric acid, commonly used as a dietary supplement and food additive. It is characterized by its white, crystalline appearance and is soluble in water, which enhances its bioavailability compared to other calcium salts. The chemical formula for calcium citrate is typically represented as C6H6CaO7, indicating that it contains calcium, citric acid, and oxygen. This compound is often utilized in the food industry as a preservative and flavoring agent, as well as in pharmaceuticals for calcium supplementation, particularly for individuals with calcium deficiencies or those at risk of osteoporosis. Calcium citrate is favored for its ability to be absorbed effectively in the presence of low stomach acid, making it suitable for a wide range of populations, including older adults. Additionally, it has a relatively low risk of gastrointestinal side effects compared to other calcium supplements. Overall, calcium citrate serves as an important source of dietary calcium while also contributing to various industrial applications.
