Molybdenum is a trace mineral that your body uses in small amounts, mostly as a component of three enzymes your body needs to metabolize amino acids, produce uric acid and to break down drugs and toxins.

Molybdenum deficiency doesn't occur in humans because it is found in many foods and is needed in such small amounts. Dietary molybdenum is found in the largest amounts in peas, lentils and other legumes, however it is also found in fruits, vegetables and many animal foods.
