I've been taking this supplement for two weeks now- didn't know this will slowly heal my digestive problem. I was always constipated before, having that kind of feeling really sucks. but when I've started taking this, I now have regular bowel movements. I just take this supplement twice a day, for better results, make sure to hydrate your body! Hope this helps!
