Calcium
Description
Calcium is the most common mineral in the body, stored almost entirely (98%) in the bones, and counts for about 2% of body weight. Generally, between 20 and 30% of the calcium provided by the diet is absorbed by the digestive tract, but absorption varies according to needs, increasing in particular during growth, pregnancy and breastfeeding.
Calcium is essential for the maintenance of bone health and the proper functioning of many enzymes and hormones.
