Molybdenum is an essential element and a co-factor for several enzymes. It is stored primarily in the liver, kidneys, spleen, lungs, brain, and muscles.
Molybdenum is a constituent of several enzyme systems. These enzymes are responsible for the breakdown of xanthine, hypoxanthine, and sulfite, and the detoxification of many harmful compounds.
The ability of tissues to store molybdenum varies with intake levels and is affected by the amount of copper and sulfate in the diet.
Please note that this section reports on claims that have NOT yet been substantiated through scientific studies.
Molybdenum has been purported to help treat arthritis.
Ongoing studies are investigating the use of molybdenum to treat certain cancers.
As indicated below, molybdenum is measured in micrograms. The SADI is the Safe and Adequate Dietary Intake. These values are given when a Daily Reference Intake (DRI) has not been established.
Infants (0 to 6 months)
Infants (6 months to 1 year)
Children (1 to 3 years)
Children (4 to 6 years)
Children (7 to 10 years)
Adolescents and adults (11+ years)
Foods containing molybdenum include legumes, cereal products, and leafy vegetables.
Molybdenum levels in plants are highly variable and dependent upon the molybdenum content of the soil in which they were grown.
Molybdenum deficiency is extremely rare and occurs due to a serious, underlying condition.
Side effects, toxicity, and interactions
Problems associated with excessive molybdenum are poorly documented. Too much molybdenum can result in a gout-like syndrome, with increased blood levels of molybdenum, uric acid, and xanthine oxidase.
Do not take molybdenum supplements if you have biliary obstruction (gallstones) or kidney problems.
Women who are pregnant or breastfeeding should consult a physician before taking any mineral supplements.
