In animal studies, Vanadium has been found to function similarly to insulin by helping to maintain blood glucose levels the same as in the control group, despite lower serum insulin, while at the same time making cell membrane insulin receptors more sensitive to insulin. In human studies, daily insulin requirements in Type I diabetics decreased by as much as 14%, and in Type II diabetics, there was an increase in insulin sensitivity observed following vanadium treatments using either vanadyl sulfate or sodium metavanadate...
