Calcium is necessary for the growth and maintenance of strong teeth and bones, nerve signaling, muscle contraction, and secretion of certain hormones and enzymes. A deficiency in calcium can lead to numbness in fingers and toes, muscle cramps, convulsions, lethargy, loss of appetite, and abnormal heart rhythms. Conversley, excess calcium (particularly from supplements) can lead to kidney stones, calcification of soft tissue, and increased risk of vascular diseases like stroke and heart attack. The DV for calcium is 1000mg. Below is a list of high calcium foods, for more, see the extended list of calcium rich foods.
