Calcium heeft in het lichaam een rol in botmineralisatie (botopbouw), bloedstolling, plasmamembraanpotentiaal, spiercontractie, hormoonafgifte, glycogeenmetabolisme en celdeling. Calcium bevindt zich in het skelet (99%), in de weefsels en in de extracellulaire vloeistoffen (onder andere het bloed).
