Molybdenum is another trace element (micronutrient or small molecule) required to activate various chemical reactions involved in the body’s excretion of metabolic waste (from cell functioning) and certain drugs.
What does molybdenum do?
Molybdenum plays a role in:
The recommended dietary allowance (RDA) for molybdenum is expressed in µg/day.

*(AI) = Adequate intake for those two age groups.
The amount of molybdenum in foods of plant origin depends on the composition of the soil in which these foods were grown. Legumes, grain products, and nuts contribute the most to dietary intake of molybdenum. Foods of animal origin, fruits, and most vegetables contain a small amount of molybdenum.
Food Sources for Molybdenum:
|Animal and vegetal food's origin|
|20 to 90µg of molybdenum for a 100g portion|
|Whole grain cereals|
|Leafy green vegetables|

Signs of molybdenum deficiency:
Benefits of molybdenum:
Excess molybdenum is only slightly toxic to humans as it is rapidly excreted in the urine.
Signs of excess molybdenum:
Molybdenum poisoning can be treated with copper, a molybdenum antagonist.
