Calcium is a mineral found in many foods. The body needs
calcium to maintain strong bones and to carry out many important functions.
Almost all calcium is stored in bones and teeth, where it supports their
structure and hardness.
The body also needs calcium for muscles to move and for
nerves to carry messages between the brain and every body part. In addition,
calcium is used to help blood vessels move blood throughout the body and to
help release hormones and enzymes that affect almost every function in the
human body.
