Zinc is an essential trace element involved in most major metabolic pathways. General signs of human zinc deficiency indicate that zinc has important functions in maintaining immune function, reproduction, healthy skin, and growth. Numerous studies support the fundamental role of zinc in normal immune response in humans. Immune cells must be able to rapidly divide in order to respond to daily challenges. Like all rapidly dividing cells, immune cells depend on adequate amounts of dietary zinc.
As a cofactor of the antioxidant enzyme superoxide dismutase (SOD), zinc can be considered an antioxidant nutrient. Zinc supplementation has been shown to increase the antioxidant activity of SOD, and provide additional support as a free radical scavenger. Body cells and tissues are vulnerable to free radical damage and reactive oxygen species (e.g., peroxides) which are produced during normal oxygen metabolism, by other chemical reactions, and by unwanted agents in the environment. Free radicals, once formed, are capable of disrupting metabolic activity and cell structure. When this occurs, additional free radicals are produced which, in turn, can alter cells and tissues. The uncontrolled production of free radicals is thought to be a major contributing factor to oxidative damage. Zinc deficiency is associated with increased production of free radicals and reactive oxygen species.
More than any other tissue in the body, the lens and retina of the eye are continually exposed to free radicals. As a part of the normal aging process, these factors can contribute to changes in the membrane structure and function of eye cells. Studies indicate zinc as an important nutrient needed to maintain healthy vision as we age.
