Mo-Zyme Forte supplies a supplemental source of molybdenum (Mo). Mo is an essential trace element, and plays an important role in human life as a cofactor for several enzymes. Although Mo deficiency is rare, deficiency may result in toxicity due to the decreased activity of enzymes requiring molybdenum, particularly the sulfite reductase enzyme. Molybdenum cofactor deficiency may also lead to a decrease in the activity of molybdenum enzymes. Each tablet of Mo-Zyme Forte supplies 150mcg of molybdenum.
