I have tried other probiotics before (the kind you have to keep in the refrigerator) but they exacerbated my chronic constipation and I had to stop taking them. These probiotics actually helped with that problem instead. I've recently made some pretty dramatic changes to my diet and my GI system had a bit of trouble adjusting to the change. I realized that I hadn't taken my probiotics for a while, so I started them again and within a day or two, things had sorted themselves out.
Bottom Line: Yes, I would recommend this to a friend
