Zinc supplements are used to prevent or treat zinc deficiency.
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.
In addition, premature infants may need additional zinc.
Increased need for zinc should be determined by your health care professional.
Claims that zinc is effective in preventing vision loss in the elderly have not been proven. Zinc has not been proven effective in the treatment of porphyria.
Injectable zinc is given by or under the supervision of a health care professional. Other forms of zinc are available without a prescription.
Once a medicine or dietary supplement has been approved for marketing for a certain use, experience may show that it is also useful for other medical problems. Although this use is not included in product labeling, zinc supplements are used in certain patients with the following medical condition:
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.
Normal daily recommended intakes in milligrams (mg) for zinc are generally defined as follows:
|Persons||U.S. (mg)||Canada (mg)|
|Infants and children birth to3 years of age||5–10||2–4|
|Children 4 to 6 years of age||10||5|
|Children 7 to 10 years of age||10||7–9|
|Adolescent and adult males||15||9–12|
|Adolescent and adult females||12||9|
If you are taking a dietary supplement without a prescription, carefully read and follow any precautions on the label. For these supplements, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to medicines in this group or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Problems in children have not been reported with intake of normal daily recommended amounts.
Problems in older adults have not been reported with intake of normal daily recommended amounts. There is some evidence that the elderly may be at risk of becoming deficient in zinc due to poor food selection, decreased absorption of zinc by the body, or medicines that decrease absorption of zinc or increase loss of zinc from the body.
It is especially important that you are receiving enough vitamins and minerals when you become pregnant and that you continue to receive the right amount of vitamins and minerals throughout your pregnancy. The healthy growth and development of the fetus depend on a steady supply of nutrients from the mother. There is evidence that low blood levels of zinc may lead to problems in pregnancy or defects in the baby. However, taking large amounts of a dietary supplement in pregnancy may be harmful to the mother and/or fetus and should be avoided.
It is important that you receive the right amounts of vitamins and minerals so that your baby will also get the vitamins and minerals needed to grow properly. However, taking large amounts of a dietary supplement while breast-feeding may be harmful to the mother and/or baby and should be avoided.
