I tried the named brand probiotics with 50 billion live cultures before and it practically did nothing to me. I wonder what went wrong during shipping process. Maybe all live cultures were dead when I received the probiotics in the mail.
On the other hand, the GNC probiotics that I bought from a local store works really well. In addition, I'm taking L-glutamine. I take these 2 supplements first thing in the morning...I take far more tablets than it instructs on label. I'm eating normal now. I read it somewhere that probiotics + L-glutamine can be a possible cure for some people.
