About Molybdenum
Essential cofactor for sulfite oxidase, xanthine oxidase, and aldehyde oxidase—enzymes critical for sulfur amino acid metabolism and uric acid production. Deficiency is extremely rare due to low requirements and widespread presence in legumes, grains, and organ meats. Supplementation is almost never necessary unless on total parenteral nutrition. Well tolerated; toxicity is uncommon even at intakes well above the RDA.
