Element #20 on the Periodic Table, Calcium (Ca) is perhaps the most important single mineral provided by Mother Earth for human health and well-being. One of the highest naturally alkaline earth metals, (a pH of 12), Calcium ions stimulate the various biological transmutation processes throughout the human body. It is so vital, that if it is not provided to the human cell daily, ions are borrowed from the body's calcium storehouse, the bones. Calcium also helps to control the movement of nutrients into the cell and is vital in eliminating waste material and toxins from the cells, stimulating the cellular membrane to remain flexible and permeable. Keep in mind that our Calcium is 99.999% pure Mother Earth Metal crystalline particles. It is NOT compounded with Carbon (Calcium Carbonate), Citrate, Aspartate, or Coral from the South Pacific. It is absorbed directly into the blood when consumed sublingually, and is clearly one of the most efficient and bio-available Calcium supplements on the market.
