Calcium citrate | C12H10Ca3O14 | CID 13136 - PubChem
Calcium citrate increases plasma calcium levels. This reduces calcium flux from osteocyte activity by reducing the secretion of parathyroid hormone (PTH). Calcium does this by stimulating a G-protein coupled calcium receptor on the surface of parathyroid cells.
Calcium citrate - Wikipedia
Calcium citrate is the calcium salt of citric acid. It is commonly used as a food additive (E333), usually as a preservative, but sometimes for flavor. In this sense, it is similar to sodium citrate. Calcium citrate is also found in some dietary calcium supplements (e.g. Citracal or Caltrate).
