Calcium phosphates are a group of compounds that are essential for the growth and maintenance of strong bones and teeth. They consist of calcium ions and phosphate ions bound together, and are found naturally in a range of foods and supplements. Synonyms for calcium phosphates include calciphos, dicalcium phosphate, tricalcium phosphate, hydroxyapatite, and brushite. Dicalcium phosphate is typically used in some toothpastes and supplements, while tricalcium phosphate is commonly found in dairy products and some baked goods. Hydroxyapatite is a major component of bone tissue and is sometimes used in medical implants, and brushite is a less common form of calcium phosphate that can be found in urinary stones.
