Calcium plays a role in clotting blood and is thought to manage blood pressure. It can also prevent some types of cancer, although the evidence supporting the latter two is still a little sparse.
The best way to appreciate the importance of calcium in the body, however, is to look at the symptoms of calcium deficiency which include muscle cramps, brittle bones, insomnia and delayed puberty in children. These symptoms are probably more a result of calcium being reduced and therefore not being able to work properly in tandem with other minerals, but it is still clear that calcium plays an essential role in maintaining good health.
