Zinc: What It Means for Your Health

Zinc is an essential trace mineral that acts as a cofactor for over 300 enzymes and is critical for immune function, wound healing, DNA synthesis, cell division, taste and smell, and protein synthesis. The body has no specialized zinc storage system, so regular dietary intake is necessary. Zinc deficiency is surprisingly common worldwide, particularly in developing countries and among vegetarians, elderly people, and those with digestive disorders.

What Does High Zinc Mean?

Above 120 ug/dL

Elevated zinc (zinc toxicity) is rare and usually results from excessive supplementation, occupational exposure, or contaminated food/water. Symptoms include nausea, vomiting, diarrhea, and metallic taste. Chronic zinc excess can cause copper deficiency (zinc and copper compete for absorption) and impaired immune function.

What Does Low Zinc Mean?

Below 60 ug/dL

Low zinc is common and causes impaired immune function (frequent infections), delayed wound healing, hair loss, skin rashes (especially around the mouth and eyes), loss of taste and smell, diarrhea, and decreased appetite. In children, zinc deficiency stunts growth. Risk factors include vegetarian diets, malabsorption, chronic kidney disease, alcohol use, and pregnancy.
