MOLYBDENUM
Molybdenum is found in several digestive enzymes: sulfite oxidase, xanthine oxidase and aldehyde oxidase.
Sulfite oxidase is used in the body to help detoxify sulfites which are found in protein foods.
All three enzymes are utilized in the body to process protein foods.
Xanthine oxidase aids the body in its production of uric acid.

The chemical Sulphite oxidase is used as a preservative in some foods and medicines. However, there are side effects:
When used as a food additive, sulphite oxidase can cause some people to develop asthma and other breathing difficulties
Supplementation is not thought to be necessary, as people rarely become deficient in Molybdenum.
The average daily intake from foods is 180 mcg.
500 mcg daily have been given to trial patients with no adverse effect, however, this is not advised: the time frame
of this experiment was not revealed in my source, but since it is known that Molybdenum can deplete the body’s
Copper resources. taking extra Molydenum over long periods could end up making you Copper and Iron deficient, and this would lead to anaemia. Supplements should contain no more than 250 mcgs. Between 75 and 250 mcgs is considered safe.
People with high uric acid levels in the blood, which gives rise to gout, should not take Molybdenum unless your health professional  advises you  to do so.

SOURCES
The best source of Molybdenum is in the dark green leafy vegetables: Spinach, silver beet, kale, comfrey
All beans, haricot, red kidney, green string beans, broad beans, are high in Molybdenum.
Whole grains, bran, wheatgerm, cereals and dairy products conatin Molybdenum.
