Molybdenum is an essential trace element that functions as a cofactor for a number of enzymes in the body, some of which are involved in the metabolism of amino acids and nucleotides. The molybdenum content of plant foods varies depending upon the soil content in which they are grown. Legumes, grain products and nuts are major contributors of molybdenum to the diet. Dietary molybdenum is efficiently absorbed through the intestine 1.
  The U.S. Food and Drug Administration (FDA) has established a Reference Daily Intake (RDI) of 75 μg molybdenum for adults and children 4 or more years of age (21CFR101.9). RDIs are a set of dietary references for essential vitamins and minerals that are considered amounts sufficient to meet the daily requirements of healthy individuals. RDIs serve as the basis for calculating the percent daily value (%DV) amounts found on dietary supplement and food labels.
