Uses For ammonium molybdate

The body needs molybdenum for normal growth and health. For patients who are unable to get enough molybdenum in their regular diet or who have a need for more molybdenum, molybdenum supplements may be necessary. They are generally taken by mouth in multivitamin/mineral products but some patients may have to receive them by injection. Molybdenum is part of certain enzymes that are important for several body functions.

A deficiency of molybdenum is rare. However, if the body does not get enough molybdenum, certain enzymes needed by the body are affected. This may lead to a build up of unwanted substances in some people.

Injectable molybdenum is administered only by or under the supervision of your health care professional.

Importance of Diet

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.

The amount of molybdenum in foods depends on the soil in which the food is grown. Some soils have more molybdenum than others. Peas, beans, cereal products, leafy vegetables, and low-fat milk are good sources of molybdenum.

The daily amount of molybdenum 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 molybdenum 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: 15 to 50 micrograms (mcg).
    • 4 to 6 years of age: 30 to 75 mcg.
    • 7 to 10 years of age: 50 to 150 mcg.
  • Adolescents and adults—75 to 250 mcg.
