Zinc.

Zinc is essential for health. It's needed for the enzymes that regulate cell division, growth, wound healing, and proper functioning of the immune system. An essential co-factor in a variety of cellular processes including DNA synthesis, behavioural responses, reproduction, bone formation, growth and wound healing.

Part of insulin and it plays a major role in the efficiency of most of the functions of the body. Zinc is necessary for the free-radical quenching activity of superoxide dismutase (SOD), a powerful antioxidant enzyme that breaks down the free-radical superoxide to form hydrogen peroxide.

Zinc is required for the proper function of T-lymphocytes.

Epidemiologic studies suggest that zinc deficiency may be associated with increased risk of cancer. Zinc supplementation is associated with decreased oxidative stress and improved immune function, which may be among the possible mechanisms for its cancer preventive activity.

The mineral also plays a role in acuity of taste and smell.

Required for proper functioning of genetics, immunity, formation of red blood cells, organ, muscle and bone function, cell membrane stability, cell growth, division, differentiation and genetics.

Importantly, zinc is vital for the metabolism of vitamin A.

To much zinc can do damage and stimulate cancer development.
