Zinc excess occurs when the body has too much of the mineral zinc.

Zinc is widely distributed in the body—in bones, teeth, hair, skin, liver, muscle, white blood cells, and testes. It is a component of more than 100 enzymes, including those involved in the formation of RNA (ribonucleic acid) and DNA (deoxyribonucleic acid).

The level of zinc in the body depends on the amount of zinc consumed in the diet. Zinc is necessary for healthy skin, healing of wounds, and growth.

People rarely consume too much zinc. Usually, zinc excess results from consuming acidic foods or beverages packaged in a zinc-coated (galvanized) container. In certain industries, inhaling zinc oxide fumes can result in zinc excess.
