What we hear most about zinc is that it’s a great immune system booster, and may even help protect against cancer and other serious diseases. Zinc does a lot more for good health than boosting the immune system, however. Zinc is also key for enzyme production, which benefits the function of major organs like the liver and kidneys, and also for skin and eye health. Lower than normal levels of zinc can cause fatigue and loss of appetite, which can definitely cause diminished levels of energy.
