Zinc is a micromineral that plays important roles in immunity, wound healing, normal growth and development, reproduction, and various metabolic processes. Recent research indicates that it may help fight the common cold and other infections; it may also be useful in treating fibromylalgia, osteoporosis, and rheumatoid arthritis.

Zinc is involved in well over metabolic process and body functions. Every cell in the body requires Zinc, with the largest amounts concentrated in the liver, kidneys, pancreas, bones, skin, eyes, and the prostate gland. It is found in the drinking water of many areas and a variety of foods, especially those high in protein. Although only very small amounts of Zinc are needed, studies indicate that many Americans don't get nearly enough of this mineral.
