The body needs zinc for normal growth and health. For patients who are unable to get enough zinc in their regular diet or who have a need for more zinc, zinc supplements may be necessary. They are generally taken by mouth but some patients may have to receive them by injection.
Zinc supplements may be used for other conditions as determined by your health care professional.
Lack of zinc may lead to poor night vision and wound-healing, a decrease in sense of taste and smell, a reduced ability to fight infections, and poor development of reproductive organs.

For good health, it is important that you eat a balanced and varied diet. Follow carefully any diet program your health care professional may recommend. For your specific dietary vitamin and/or mineral needs, ask your health care professional for a list of appropriate foods. If you think that you are not getting enough vitamins and/or minerals in your diet, you may choose to take a dietary supplement.
Zinc is found in various foods, including lean red meats, seafood (especially herring and oysters), peas, and beans. Zinc is also found in whole grains; however, large amounts of whole-grains have been found to decrease the amount of zinc that is absorbed. Additional zinc may be added to the diet through treated (galvanized) cookware. Foods stored in uncoated tin cans may cause less zinc to be available for absorption from food.
The daily amount of zinc needed is defined in several different ways.
- For U.S.—
- Recommended Dietary Allowances (RDAs) are the amount of vitamins and minerals needed to provide for adequate nutrition in most healthy persons. RDAs for a given nutrient may vary depending on a person's age, sex, and physical condition (e.g., pregnancy).
- Daily Values (DVs) are used on food and dietary supplement labels to indicate the percent of the recommended daily amount of each nutrient that a serving provides. DV replaces the previous designation of United States Recommended Daily Allowances (USRDAs).
- For Canada—
- Recommended Nutrient Intakes (RNIs) are used to determine the amounts of vitamins, minerals, and protein needed to provide adequate nutrition and lessen the risk of chronic disease.
