Athletes have used vanadyl sulfate extensively as part of their daily supplementation program. It is a form of the trace element vanadium, which is important for normal growth and development. Vanadyl sulfate may help support glucose metabolism by its insulin-like effects in the liver, skeletal muscle, and adipose tissue, by activating glucose transport at the cellular level. Preliminary research suggests that sourcing natural vanadyl sulfate may help maintain healthy blood sugar levels when used as part of a healthy diet.
