Calcium plays a vital role in nerve and muscle function, clotting of blood, enzyme regulation, insulin secretion and overall bone strength.
When you don't get enough calcium or assimilate it sufficiently, your body draws calcium out of your bones instead. This bone loss over a period of years may lead to osteoporosis - thinning of the bones (porous bones). The bones become weak, brittle and easy to fracture, particularly the bones of the wrist, hips and spine.
Loss of height and curvature of the spine may also develop from lack of calcium, as may periodontal disease - the deterioration of the jaw bones that support the teeth.
