It worked fairly well, I wasn't expecting a completely flat tummy, but it didn't work amazingly well for me - in that I wanted it to help control my bloating. I've tried most of the Optibac range and this one seemed to work better. Probiotics seem like a minefield to find the right one!

It does work after 4th day I noticed the results. No bloating. I then stopped after 7 days and took optibac extra strength but became very bloated and constipated. Back on the optibac 7 day again.

I purchased these after being poorly, I did everything to try and settle my stomach. This is a wonder product! Worked almost instantly, can't recommend highly enough.
