Patient Education

Zinc


What is it? Zinc is a mineral. It is called an "essential trace element" because very small amounts of zinc are necessary for human health. Since the human body does not store excess zinc, it must be consumed regularly as part of the diet. Common dietary sources of zinc include red meat, poultry, and fish. Zinc deficiency can cause short stature, reduced ability to taste food, and the inability of testes and ovaries to function properly.

Zinc is used for the treatment and prevention of zinc deficiency and its consequences, including stunted growth and acute diarrhea in children, slow wound healing, and Wilson's disease. Zinc is also used for many other conditions. There is some scientific evidence to support its use for some of these conditions. But for most, there is no good scientific evidence to support its use.

Coronavirus disease 2019 (COVID-19): While zinc may have benefit for the common cold and other airway infections, there is no good evidence to support using it for COVID-19. Also, zinc gluconate 50 mg daily does not seem to be beneficial. Follow healthy lifestyle choices and proven prevention methods instead.
