Molybdenum nutritional need

The molybdenum requirement of ruminants was calculated to be <100 pg/kg dry matter of ration monogastric animals may need even less [36]. For human adults it is calculated to be 25 pg/day [37]. Apart from parenteral nutrition molybdenum deficiency need not be reckoned with in animals and humans. 

Molybdenum is considered an ultra-trace element with an approximate amount of 5 mg in the adult human body. It is a cofactor for at least three enzymes in humans (sulfite oxidase, xanthine oxidase, and aldehyde oxidase) and is involved in the catabolism of sulfur-containing amino acids, purine, and pyrimidine. A better understanding of human molybdenum metabolism is needed in order to give evidence-based recommendations regarding optimal nutrition, although molybdenum deficiency and associated pathological symptoms have not yet been observed in humans [74].
