I tried berberine years ago as a sort of Metformin substitute when I was pre diabetic (or more accurately, before I went to a doctor for a proper diabetes diagnosis). It seemed to have a small effect on blood sugar but pretty bad GI side effects. Nearly as bad as Metformin but didn't work as well. I definitely wouldn't take them together!
