Vanadium

Type: Trace Element
Periodic Element: (V)
RDA:None listed. Tolerable Upper Intake Level (UL) of dietary vanadium, beyond which adverse effects may occur, is set at 1.8 mg/day.
Importance- To Body:
(Not Considered Essential)
Distribution- In Body:
* Approx. % of Body Mass
Dietary intake is estimated at 6 to 18 µg/day, with less than 5% absorbed. The Tolerable Upper Intake Level (UL) of dietary vanadium, beyond which adverse effects may occur, is set at 1.8 mg/day
Vanadium compounds are poorly absorbed through the gastrointestinal system.
Excess Effects:
Effects have been reported after oral or inhalation exposures on blood parameters, liver, neurological development, and other organs in rats.
Deficiency Effects:
Deficiencies in vanadium result in Reduced Growth in rats, (application to human physiology unknown).
Sources Food:
None listed
Sources Environmental/Geographic:
The vanadyl ion is abundant in seawater, having an average concentration of 30 nM. Some mineral water springs also contain the ion in high concentrations. For example, springs near Mount Fuji contain as much as 54 μg per liter.
The cosmic abundance of vanadium in the universe is 0.0001%, making the element nearly as common as copper or zinc.
Supplemental information:
All vanadium compounds should be considered toxic.
