Zinc Overview

Zinc is an essential trace mineral involved in many biological processes in the body, including the manufacture of genetic materials and proteins. Zinc plays an important role in immune function, wound healing, taste and smell, thyroid function, and insulin action. Symptoms of a zinc deficiency include mental lethargy, lack of appetite, poor sense of smell and taste, and decreased thyroid function. Zinc deficiencies are rare in the US, however, alcoholism and chronic kidney disease can create a zinc deficiency. Zinc works closely with vitamin A. Zinc monomethionine is a highly-absorbable form of zinc.
