2009 Review of probiotic trial research finds only Bifantis able to claim efficacy for IBS symptoms

With these probiotics one works better for one person while not for another or possibly making them worse. It seemed like Align caused me to begin to flare, while Dr. Ohriha's seem to help clear up constipation problem I was having. Of course it could all be just a coincidence as well as other factors involved casing it. Only way to know is for one to try it out and see.
