Should You Be Afraid Of Your Calcium Supplements?
Dec 01, 2014· You'd get more calcium by swallowing the calcium bottle cap than from the calcium! Calcium, being a mineral, as with all minerals, in order to get the amount needed by the body the mineral must be accompanied by a "carrier" or "mineral transporter". In other words the mineral, calcium in this case, is "escorted into the cells" by a carrier such as carbonate, citrate, aspartate, or orotate (among .

Causes of Calcium Carbonate Precipitation. The degree to which calcium carbonate occurs in water at atmospheric pressure depends on the pH and temperature of the water. At pH values of less than about 6, mostly dissolved carbon dioxide and a small amount of carbonic acid exist in water. At pH values of between about and 10, bicarbonate is dominant.
