    Molybdenum 

    Other name(s):

    ammonium molybdate

    General description

    Molybdenum is an essential element. It’s a co-factor for several enzymes. It is stored mainly in the liver, kidneys, spleen, lungs, brain, and muscles.

    Molybdenum is a part of several enzyme systems. These enzymes are in charge of the breakdown of xanthine, hypoxanthine, and sulfite. They also break down and detoxify many harmful compounds.

    The ability of your body to store molybdenum varies with intake levels. It’s affected by the amount of copper and sulfate in your diet.

    Unsubstantiated claims

    There may be benefits that have not yet been proven through research.

    Molybdenum may help treat arthritis. Studies are also looking to see if it can treat some types of cancers and neuropsychiatric disorders.

    Recommended intake

    Molybdenum is measured in micrograms (mcg). The daily RDA is the Recommended Dietary Allowance.

    Foods that have molybdenum include legumes, cereals, and leafy vegetables.

    Molybdenum levels in plants vary. They depend on the amount in the soil in which they were grown.

    Molybdenum deficiency is very rare. It only occurs due to a serious, underlying issue.

    Side effects, toxicity, and interactions

    Too much molybdenum can cause a gout-like syndrome. Symptoms can include high levels of molybdenum in your blood, uric acid, and xanthine oxidase.

    You shouldn’t take molybdenum supplements if you have gallstones or kidney problems.

    Women who are pregnant or breastfeeding should talk to their healthcare providers before taking any supplements.

    Molybdenum supplements can cause a copper deficiency. This is because molybdenum drives copper from body tissues.
