Sources Of Molybdenum

Animal Products -meats - pork, lamb, beef liver
Nuts/seeds - sunflower seeds
Vegetables - soybeans, lima beans, lentils, peas
Grains - buckwheat, oats, barley, wheat germ, sorghum
Occupational sources - working around metal fumes. Molybdenum is used to make stainless steel, photographic chemicals, lubricants, pigments and reagents


  • In the blood, molybdenum is most commonly found in a complex with copper.
  • Molybdenum concentrates in the liver, kidney, bone and significant amounts are found in the dental enamel and hair.
  • The main route of excretion is through the kidneys.

Roles In The Body

  • Molybdenum is an ultra-trace mineral.
  • Molybdenum is required for xanthine oxidase, an enzyme involved in the formation of uric acid.
  • In animals, another enzyme, aldehyde oxidase, also requires molybdenum. This enzyme is involved in detoxification.
  • Molybdenum has been shown in animals to be involved with fat, purine and sulfate metabolism.
  • It is also involved in detoxification and
    intimately involved in copper metabolism.

Synergetic Nutrients

  • Molybdenum is considered to be synergistic with iron and sulfur.
  • Molybdenum also raises sodium levels and is synergistic with vitamins B1 and B3 (xanthine oxidase).

Antagonistic Nutrients

  • Molybdenum is a powerful copper antagonist. Most copper antagonists such as zinc displace copper. A unique property of molybdenum is that it binds or complexes directly with copper and facilitates its removal. This enables copper to be removed from the body without the common side effects that often occur with copper removal.
  • Another reason for this action is that molybdenum raises sodium, offsetting the sodium-lowering effect that occurs when copper is eliminated.
  • Molybdenum absorption is antagonized by copper, sulfur, methionine and a high-protein diet.
  • Molybdenum metabolism is antagonized by manganese, zinc and at times sulfur.
