Initially I had to just take half of a tablet because I had to get used to it. Then after about a week I took the full tablet and noticed a massive improvement in my stomach. I was no longer getting IBS in my stomach which I had been getting for several years. I did try other probiotics and I used to go and see the doctor frequently about my stomach issues. I had an endoscopy and they found nothing. I even eliminated certain foods to try and find if that would help. Nothing changed though until I took your probiotics. I have been taking them for 3-4 months now and have had no problems with my stomach. I would recommend them to everyone.
