Molybdenum is a trace element that rarely gets much attention, but serves the body with highly important detoxification functions. It is almost impossible to be deficient in unless you practically starve yourself to death, and therefore worrying about including certain food sources or supplements is unnecessary. The RDA is set at 45 mcg per day and can be obtained without a second thought for most people.


  • Metabolism of purines
  • Uric acid metabolism
  • Antioxidant activities
  • Normal metabolism of sulfur containing amino acids

Primary deficiency symptoms and diseases

  • Elevated sulfites and xanthines in the blood
  • Excess methionine in the blood

Food sources

Molybdenum is easily obtained through protein containing foods, and unless you are purposely trying to kill yourself of starvation, it should not be an issue to obtain.

  • Meat
  • Fish
  • Eggs
  • Legumes
  • Whole grains


Supplements of molybdenum are quite unnecessary. Taking extra molybdenum in hopes of having enhanced detoxification is mostly a waste of money. Supplements do exist, but much like phosphorous, they are not needed.
