Calcium plays an important part in our diets, it is essential for the
formation and maintenance of strong bones and teeth. 99% of calcium in our body
is found in our teeth and skeleton with 1% found in the blood serum. Our bones
are constantly being broken down and reformed and the calcium we take in
helps prevent an excessive loss of calcium from our bones.
Calcium is also important in regulating muscle contraction and relaxation, including our heart. Calcium activates
enzymes that are vital in a number of metabolic functions and calcium is vital in blood clotting.
Growth, pregnancy and lactation make extra demands on our supply of calcium
and it is especially important that during this time calcium supplements are
taken. If our bones are strong as children then the risk of osteoporosis in
latter life can be prevented.
