"Vanadium is a trace mineral that is found in many foods. Scientists aren t sure, but your body may need vanadium in tiny amounts. It may be involved in normal bone growth. However, scientists aren't sure exactly what effects vanadium may have, or what amount might be helpful. They do know high doses of vanadium may be unsafe. Most of the studies using vanadium have been animal studies. Only a few clinical trials involving humans have been done. Because of that, vanadium isn't recommended for any disease or condition. However, it may have an effect on blood sugar in people with diabetes."
