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 doesn't 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 disease. Zinc is also used for acne, diabetes, anorexia, burns, and many other purposes.
