PTH regulates how much calcium is absorbed from your diet, how much calcium is excreted by your kidneys, and how much calcium is stored in your bones. We store many pounds of calcium in our bones, and it is readily available to the rest of the body at the request of the parathyroid glands. PTH increases the formation of active vitamin D, and it is active vitamin D that increases intestinal calcium and phosphorus absorption.

— controls the pH of the small intestines — loss of calcium from alkalinity – Slows transit time of calcium through the intestines, allowing for more time for absorption. Metabolism favorably affected by the following minerals: * Biochemical and mineral balance is a most important factor of utilization.
