Molybdenum Information and Benefits

Molybdenum is an essential trace mineral in animal and human nutrition. It is found in several tissues of the human body and is required for the activity of some enzymes that are involved in catabolism, including the catabolism of purines and the sulfur amino acids. Molybdenum is a transition metal with atomic number 42 and an atomic weight of 95.94 daltons. Its symbol is Mo. Compounds of molybdenum are among the scarcer constituents of the earth's crust. In fact, molybdenum is only about three times more abundant than gold. The principal ore of molybdenum is molybdenite (molybdenum disulfide). Organic forms of molybdenum are found in living matter, from bacteria to animals, including humans.

Uses for Molybdenum

Preliminary evidence suggests that molybdenum, through its involvement in detoxifying sulfites, might decrease the risk of sulfite-reactive asthma attacks. However, a physician should be involved in the evaluation and use of molybdenum in connection with sulfite sensitivity.

Molybdenum is indicated in cases of molybdenum deficiency due to prolonged use of total parenteral nutrition. Despite some epidemiological evidence showing a higher incidence of esophageal carcinoma in those who live in areas where the soil is low in molybdenum, there is as not currently any indication for the use of supplemental molybdenum in the prevention of cancer. Claims that molybdenum may help prevent anemia, dental cavities, and help in cases of sexual impotence have no credible support.

Dosage and Administration

Molybdenum supplements are usually available in the form of sodium molybdate and sometimes in the form of ammonium molybdate. Molybdenum is found in combination products, including multivitamin/multimineral formulas. A typical supplementary dose is 75-250 micrograms daily. The amounts of molybdenum on nutritional supplement labels are expressed as elemental molybdenum.
