Ingredient overview
What it is
Approximately 99% of the body's calcium is stored in bones and teeth. The remaining amount supports tightly regulated functions in blood, muscles and nerves.
- Scientific identity: Calcium; body distribution: approximately 99% skeletal hydroxyapatite.
- How it works: Supplied as a compound: Calcium is never taken as a bare metal - each form differs in elemental content and in how much it depends on stomach acid. Absorbed in the small intestine: Uptake is active and vitamin D dependent at ordinary intakes, and passive at higher ones.
- Primary function: Adequate calcium intake helps maintain normal bone structure, muscle function, nerve transmission and blood clotting.
- What it supports: Calcium helps maintain the strong skeletal framework, coordinated muscle movement and steady nerve signalling you rely on every day.
- Important consideration: The elemental mineral amount is more meaningful than the weight of its source compound.
