Supplement Reviews

Vanadyl Sulfate

What it is: Vanadyl sulfate is a supplemental form of vanadium, which is a trace mineral found in plants, animals, and soil..

What it does: Vandyl sulfate is purported to help build muscle and facilitate weight loss.

Verdict: Studies suggest that vanadium does help to control blood glucose, thus improving insulin function. This indicates it may have some potential as an aid to those who are diabetic or insulin resistant. However, the majority of studies on supplemental vanadyl sulfate have been small and of limited duration. Moreover, the dosages used to achieve a beneficial effect have been in excess of 100 milligrams a day, far beyond the upper limit established by the Institute of Medicine. Although no specific toxicity has been reported, it is unclear what long-term side effects may be associated with high levels of intake. Therefore, vanadyl sulfate should not be considered for supplemental use until research provides more answers.
