Tricalcium phosphate

Tricalcium phosphate is a mineral salt composed of calcium and phosphate, naturally found in the bones and teeth of mammals. It also occurs naturally in certain sedimentary rocks and can be obtained through chemical synthesis for food and pharmaceutical use. Its most common form in the dietary supplement field is noted Ca₃(PO₄)₂. Owing to its high calcium content, it is widely used as a bioavailable source of calcium in fortified foods, particularly plant-based milks such as soy or oat milk. Calcium contributes to the maintenance of normal bones and teeth, as well as normal muscle function and the transmission of nerve impulses. Phosphate, the second constituent, also plays an essential role in cellular energy metabolism. In the manufacture of dietary supplements, tricalcium phosphate is also valued for its technological properties: it acts as a bulking agent, thickener or glidant, facilitating the shaping of tablets and capsules. Supplementation may be of interest for people whose dietary calcium intake is insufficient, particularly those following a diet that excludes dairy products.
