Zinc is a necessary trace element in the diet, forming an essential part of many enzymes, and playing an important role in protein synthesis and in cell division. Zinc deficiency is associated with anemia, short stature, hypogonadism, impaired wound healing, and geophagia. It is known by the symbol Zn. Zinc is an essential mineral and heavy metal that is included in most over-the-counter multivitamin and mineral supplements, and is used therapeutically in higher doses because of its ability to block copper absorption as maintenance therapy of Wilson disease. Zinc has not been associated with worsening of serum enzyme elevations during therapy or with clinically apparent liver injury.
