It serves many functions and is essential for growth, reproduction, and daily maintenance of our bodies. Calcium is paramount in the formation of bone and teeth. It is also used by the body in blood clotting, nerve conduction, the contraction and relaxation of the muscles, a normal heartbeat, hormone regulation, and activation of certain enzymes. Therefore, it is essential that both men and women get adequate amounts of calcium from their diets, and from supplements if necessary. Requirements vary with age and usually increase with age, or with conditions or medications that may influence a persons' needs.
Osteoporosis is one of the most common disorders that is associated with insufficient calcium.
This condition is the breakdown and weakening of the bone causing brittle bones and leading to a higher risk of breaks and fractures. Women are particularly at risk when menopause begins and the body starts to reduce the amount of estrogen produced. Women on estrogen replacement therapy are at a lower risk of developing osteoporosis. In addition to aging, bone weakening can also be caused by long-term use of steroids such as prednisone or inhaled corticosteroids commonly used in asthma. There are several other conditions that can put people at high risk for osteoporosis.
