Molybdenum deficiency has not been observed in healthy people. There are rare cases of molybdenum deficiency from genetic defects or from faulty intravenous feeding. Signs of molybdenum deficiency may include low levels of uric acid in the blood and urine and an increase of sulfite in the urine.
DIETARY SOURCES OF MOLYBDENUM
A survey of molybdenum intake of Americans indicated that average intakes are above the RDA. The richest dietary sources for molybdenum are beans, lentils, and peas. Whole grains and nuts are good sources. Other foods, such as animal products, vegetables, and fruits are low in molybdenum. The molybdenum content of food can vary considerably.
The Food and Nutrition Board of the Institute of Medicine has set RDAs for molybdenum, as seen in Table 13-6. Adequate Intakes (AI) were set for infants. Molybdenum found in nutritional supplements is often in the form of sodium molybdate or ammonium molybdate.
