The active form is actually a hormone and thus has profound effects on the body. It maintains the proper functioning of several body organs but its major function is to increase the blood calcium and phosphorus level by promoting their absorption from the intestines and then later to promote the reabsorption of calcium form the glomerular filtrate in the kidneys. In this way it has profound effects on the health of the bones by not only supporting the remodeling process but also proper bone mineralization.

Zinc is acknowledged as essential to the human organism. It is a trace element found in over a hundred and up to three hundred enzymes. It is the second most important mineral in the body, after iron.

Zinc is naturally found in red meat, milk, spinach, nuts, oysters, beans and oats. Low zinc counts can attribute to a weakened immune system, interfere with muscle building, cause diarrhea and all kind of other deficiencies.
