Zinc

Zinc is an essential mineral that is naturally found in the diet, primarily in dairy and animal-based foods. Zinc plays many important roles to help the body function optimally. Zinc is involved in most metabolic processes in the human body. It is involved in collagen synthesis, carbohydrate metabolism, glucose utilization, insulin production, and in the formation of bone. Zinc helps to support natural resistance and is required for normal reproductive function. GNC offers a variety of zinc supplements, such as pills, lozenges, liquids, and gummies.
