I've noticed no side effects in low dosages and my A1C has improved but hard to seperate that from other confounding factors. http://www.lef.org/featured-articles/metformin_dosage.html http://www.lef.org/featured-articles/metformin_dosage.html This is at very low dosage, 500mg once per day, but again, on and off, I mostly forgot to take it.
