Calcium is critical for building bones and teeth during childhood and for maintaining strong bones and teeth thereafter. In the rest of the body, calcium supports heart function, circulation, nerve function and muscle tone. <br/><br/> Vitamin D increases the absorption of calcium, so it is important to make sure your diet contains sufficient amounts of that nutrient. <br/><br/> Kirkman’s calcium capsules use Bisglycinate amino acid chelate, which has been demonstrated to have superior absorption qualities.
