Ingredient overview
What it is
Calcium citrate combines calcium with citric acid and provides approximately 21% elemental calcium by weight. Its solubility depends less on stomach acidity than calcium carbonate.
- Scientific identity: Calcium Citrate; ingredient form: Tricalcium dicitrate.
- How it works: Dissolves independently of stomach acid: The citrate pairing keeps the calcium soluble whether or not stomach acid is plentiful, unlike calcium carbonate. Absorbed in the small intestine: Freed calcium ions are taken up along the gut wall, actively at lower doses and passively at higher ones.
- Primary function: Calcium supports normal bone structure, tooth maintenance, muscle contraction and nerve signalling.
- What it supports: Calcium Citrate helps build the mineral foundation for stronger-feeling daily movement, dependable muscle function and long-term bone maintenance.
- Important consideration: The elemental mineral amount is more meaningful than the weight of its source compound.
