This form of zinc is well-tolerated and well-absorbed. Zinc is a trace mineral that is important for healthy functioning of all organs. It is essential for more than 30 enzyme reactions that feed into a variety of homeostatic functions. Zinc is located at the active site of superoxide dismutase (SOD), a major protective antioxidant enzyme, and zinc-dependent enzymes are involved in growth, immunity, and tissue renewal. Zinc is especially important for healthy functioning of the prostate and the male reproductive system.
