Phosphoric acid, calcium salt (1:)

Indications

For use as an over the counter calcium and phosphate supplement, antacid, or a source of calcium and phosphate in toothpaste .

Background

Calcium phosphate is typically available as an over the counter supplement, antacid, or as an added ingredient in some toothpastes .

Definition

ChEBI: Tricalcium bis(phosphate) is a calcium phosphate.

Agricultural Uses

Calcium phosphate [Ca₃(PO₄),] is a white insoluble powder and is the main constituent of bones. Calcium phosphate occurs naturally as rock phosphate in the mineral apatite Ca₅(PO₄)₃,which contains OH^-, F^- and Cl^- ions to a small extent.
Calcium ions and hydrogen phosphate ions react in the presence of an alkali to produce calcium phosphate.
Calcium phosphate is used extensively as a fertilizer. Dicalcium phosphate is a common constituent of nitrophosphate fertilizers and of compound fertilizers formed by ammoniation of superphosphates. Calcining of phosphate rock, sodium carbonate and silica in a rotary kiln at 1250°C gives rhenania, or calcium sodium phosphate.

Pharmacokinetics

Calcium phosphate reacts with acid in the stomach to raise the pH . In toothpaste it provides a source of calcium and phosphate ions to support remineralization of the teeth . As a supplement it provides a source of calcium and phospate, both of which are important ions in bone homeostasis.
