MANGANESE SUPPLEMENTS (Systemic)

Category

• Nutritional supplement, mineral

Description

Manganese supplements are used to prevent or treat manganese deficiency.

The body needs manganese for normal growth and health. For patients who are unable to get enough manganese in their regular diet or who have a need for more manganese, manganese supplements may be necessary. Manganese helps your body break down fats, carbohydrates, and proteins. It does so as part of several enzymes.

Manganese deficiency has not been reported in humans. Lack of manganese in animals has been found to cause improper formation of bone and cartilage, may decrease the body"s ability to use sugar properly, and may cause growth problems.

Injectable manganese supplements are given by or under the supervision of a health care professional.

Manganese supplements are available in the following dosage forms:

• Oral
• Manganese is available orally as part of a multivitamin/mineral combination.

• Parenteral
• Manganese Chloride
  • Injection (U.S.)
• Manganese Sulfate
  • Injection (U.S.)

Importance of Diet

Manganese is found in whole grains, cereal products, lettuce, dry beans, and peas.

The daily amount of manganese 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.

Because a lack of manganese is rare, there is no RDA or RNI for it. The following daily intakes are thought to be plenty for most individuals:

• Infants and children—
  • Birth to 3 years of age: 0.3 to 1.5 milligrams (mg).
  • 4 to 6 years of age: 1.5 to 2 mg.
  • 7 to 10 years of age: 2 to 3 mg.
• Adolescents and adults—2 to 5 mg.

Before Using This Dietary Supplement

If you are taking this dietary supplement without a prescription, carefully read and follow any precautions on the label. For manganese, the following should be considered:

Allergies—Tell your health care professional if you have ever had any unusual or allergic reaction to manganese. Also tell your health care professional if you are allergic to any other substances, such as foods, preservatives, or dyes.

Pregnancy—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.

However, taking large amounts of a dietary supplement while breast-feeding may be harmful to the mother and/or baby and should be avoided.

Children—Problems in children have not been reported with intake of normal daily recommended amounts.

Older adults—Problems in older adults have not been reported with intake of normal daily recommended amounts.

Medicines or other dietary supplements—Although certain medicines or dietary supplements should not be used together at all, in other cases they may be used together even if an interaction might occur. In these cases, your health care professional may want to change the dose, or other precautions may be necessary. Tell your health care professional if you are taking any other dietary supplement or any prescription or nonprescription (over-the-counter [OTC]) medicines.

Other medical problems—The presence of other medical problems may affect the use of manganese. Make sure you tell your health care professional if you have any other medical problems, especially:

• Biliary disease or
• Liver disease—Taking manganese supplements may cause high blood levels of manganese, and dosage of manganese may have to be changed
