New Roots Herbal Molybdenum - A critical cofactor within enzymes that drive the process of amino-acid metabolism. It’s also necessary for cellular function and nitrogen metabolism. Among the enzymes with molybdenum is sulfite oxidase, which breaks down sulfites present in protein and in chemical preservatives. Should your body not be able to break down these sulfites, a toxic buildup results, which could result in an allergic like reaction. Most healthy people get more than the recommended daily allowance (RDA) of molybdenum from dietary sources; however, people who have a genetic condition that interferes with the absorption of molybdenum, or who receive nutrition intravenously due to a prolonged illness, may be at risk for molybdenum deficiency.
