My Endocronoligist Sent Me An Article From Life Extension Re;

My endocronoligist sent me an article from life extension Re; 3 supplements to help diabetics. I do not take prescription drugs, trying to lower with diet and Berberine Plus. But the article talked of Mulberry leaf extract, Sorgham extract and Phloridzin taken 3 x day before meals was shown to be effective, but dosage was not shown. any ideas ?
