What is zinc, and what is it used for?

Zinc is an essential trace mineral that is required in minute quantities for human health. Zinc formulations are used to supplement natural zinc deficiency, and to treat common colds and Wilson's disease, a rare genetic disorder that causes copper accumulation in the body, especially in the liver, brain, and the corneas of the eyes.

Zinc is a micronutrient that plays an important role in the maintenance of the senses of smell and taste and a healthy immune system, cell growth and division, wound healing, and breakdown of carbohydrates. Zinc is essential for normal growth and development during pregnancy and childhood. Zinc also enhances insulin function. Zinc prevents the absorption of copper in the intestinal tract and is used to prevent copper buildup in Wilson's disease.

Zinc is available in dietary sources including red meat, poultry, fish, shellfish, eggs, whole grains, dairy products, legumes, certain vegetables, nuts, and seeds.

Uses of zinc formulations include the following:

Oral mineral supplement to meet the daily requirement
Supplementation for patients totally dependent on intravenous nutrition (total parenteral nutrition)
Common cold
Wilson's disease

Warnings

Do not take oral zinc supplements if you are hypersensitive to any of the components of zinc formulations.
Zinc intravenous solutions must not be directly infused into the vein but administered after admixing with the parenteral nutrition solution. Direct injection into the vein can cause vein inflammation and damage, and blood clot formation (thrombosis).
Zinc sulfate injection contains aluminum and may lead to aluminum toxicity.
Do not use zinc intranasally (product Zicam), there is a risk of permanent loss of the sense of smell.

What are the side effects of zinc?

Common side effects of zinc include:

Nausea
Vomiting
Stomach irritation
Deterioration of neurological functions
Elevation in the levels of enzymes including alkaline phosphatase, lipase and amylase, which return to high normal within the first one or two years of zinc therapy
Copper deficiency
Hypersensitivity reactions
