ProBeta® is the world’s most extensively researched and clinically tested Gymnema-sylvestre product for supporting healthy blood sugar. It is what we refer to as a super-extract. Our work started over forty years ago with clinical research on the Gymnema-sylvestre plant and its effect on blood sugar levels and pancreatic function. We developed four subsequent extracts of the plant, each one a more refined version of the previous, and twenty years later in 1990, we published ground breaking research on GS4, our fourth extract, in a paper entitled the Antidiabetic effect of a leaf extract from Gymnema sylvestre in non-insulin-dependent diabetes mellitus patients, in the Journal of Ethnopharmacology.Clinical research on our formulae for diabetic health, cardiovascular health and protection from oxidative damage are available in the public domain.
