Values are Adequate Intakes (AI). ND= Tolerable Upper Intake Levels (UL) are not determinable
due to lack of data of adverse effects in this age group and concern with regard
to lack of ability to handle excess amounts.
Molybdenum deficiency is rare, unless the diet
contains high amounts of the antagonistic substances such as, sulfate, copper
Signs of molybdenum deficiency are mouth and gum disorders, hypouricemia, hyperoxypurinemia, mental disturbance, and coma, as seen in patients with 'acquired molybdenum deficiency' resulting from parenteral methionine therapy.
Symptoms such as gout (inflammation of the joints due
to accumulation of uric acid) are possible due to high blood uric acid
concentrations and accumulation of uric acid around the joints. This occurs
especially when molybdenum intakes exceed 10 to 15 mg daily.
Gout affects primarily males over the age of 40 and occasionally, postmenopausal women. One aspect of gout related to molybdenum is decreased uric acid excretion caused by molybdenum and sulfur binding to copper in the kidneys.
Caution with pregnancy or nursing, consult physician before using.
Information on the relationship between substances and disease is provided for general information, in order to convey a balanced review of the scientific literature. In many cases the relationship between a substance and a disease is tentative and additional research is needed to confirm such a relationship.
earlier research in the Utano National Hospital in Japan was conducted on 60
patients undergoing long-term hemodialysis. Although serum molybdenum
concentrations decreased significantly after hemodialysis, 9 patients with
dialysis related arthritis had elevated serum molybdenum concentrations.
Abnormal molybdenum accumulation may contribute to dialysis-related arthritis.
