Vanadium is an ultra-trace mineral found in the human diet and the human body. It is essential for some animals. Deficiency symptoms in these animals include growth retardation, bone deformities, and infertility. However, vanadium has not been proven to be an essential mineral for humans.
Where is it found?
Vanadium is found in very small amounts in a wide variety of foods, including seafood, cereals, mushrooms, parsley, corn, soy, and gelatin.
Vanadium has been used in connection with the following condition

and relatively consistent scientific data showing a substantial health benefit. Contradictory, insufficient, or preliminary studies
suggesting a health benefit or minimal health benefit. For an herb, supported by traditional use but minimal
or no scientific evidence. For a supplement, little scientific support and/or minimal health
benefit. |

Who is likely to be deficient?
Deficiencies of vanadium have not been reported in humans, and it is not known whether this mineral is essential for humans.
How much is usually taken?
As yet, research indicates that most people would not benefit from vanadium supplementation. Optimal intake of vanadium is unknown. If vanadium turns out to be essential for humans, the estimated requirement would probably be less than 10 mcg per day. An average diet provides 15–30 mcg per day.
Are there any side effects or interactions?
Information about vanadium toxicity is limited. Workers exposed to vanadium dust can develop toxic effects. High blood levels have been linked to manic-depressive mental disorders, but the meaning of this remains uncertain.1 Vanadium sometimes inhibits, but at other times stimulates, cancer growth in animals. However, the effect in humans remains unknown.2
Vanadium is not known to interact with other nutrients.
At the time of writing, there were no well-known drug interactions with vanadium.
