What it does in the body
Calcium is a mineral found mainly in the hard part of bones, where it is stored.1 It is important in building and maintaining bones and teeth and plays a role in other functions such as muscle contraction, blood clotting and regulation of heartbeat.2
Studies indicate that almost 30 per cent of Canadians are lacking in sufficient levels of calcium. Most often, calcium supplements are suggested by medical professionals to be used during pregnancy as well as for the treatment of osteoporosis and high blood pressure.3
