Zinc is an essential trace element commonly found in red meat, poultry, and fish. It is necessary in small amounts for human health, growth, and sense of taste.
Zinc is found throughout the body. The body does not store excess zinc, so it must be obtained from the diet. It’s needed for immune function, wound healing, blood clotting, thyroid function, and much more. It also plays a key role in maintaining vision and might have effects against viruses.
People commonly use zinc for zinc deficiency, diarrhea, and Wilson’s disease. Zinc is also used for acne, diabetes, anorexia, burns, and many other purposes. 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. There is also no good evidence to support using zinc for COVID-19.
