Vanadium treatment of type 2 diabetes enhanced by organic ligands

Vanadyl ions can act in an insulin-like manner in the body. Thus, when taken orally they may potentiate insulin’s effects, which can potentially improve situations of type 2 diabetes (1).

Bioavailability of vanadyl compounds, however, can depend on whether of organic or inorganic nature (2). The organic bis-ligand oxovanadium appear to be far more bioavailable and efficacious than inorganic vanadyl sulfate (2).

According to a couple of trials performed earlier this year in Canada, the organic version taken in doses of 10-90mg has no adverse effects (2). Further, it was found to help reduce fasting blood glucose levels and improves glucose tolerance (2).
