Does anyone have experience with VSL3? I've tried allot of probiotics, and recently tried prescript-assist which is almost as expensive as VSL3, and Chris Kresser recommended (not that it means allot). I've also been looking for mutaflor in north America, but it only seems to exist in Europe. Also, I've heard anecdotal reports that there is a double strength version of VSL3, although I'm not sure what strains VSL3 has that's better than the others. It seems to contain some generic strains, but supposedly arrives on ice.
