Other Cool Facts

  • Calcium is very important for the human body. 99% of the body's calcium is stored in the bones and teeth, helping to strengthen them. The other 1% helps with muscle movement allowing nerves to carry messages between the brain and our body parts. It helps blood vessels move blood around and assists with the release of hormones and enzymes. If you don't have calcium you can't live. The name calcium comes from the Latin word calx which means lime.
  • Calcium is also found in other minerals such as gypsum (calcium sulfate) and fluorite (calcium fluoride) and it occurs to a lesser extent in igneous and metamorphic rocks, mainly in silicate minerals.
