This might be TMI, but I am diagnosed with Cystic Fibrosis. I have gone through extensive gastrointestinal issues, most recently being diagnosed with C Diff. I bought the "Just Saccharomyces boulardii" and the very next time I went to the doctor.... it was cleared!!! This literally saved me from getting a fecal transplant (thank god!!). If you are struggling with any gastrointestinal issue weather its as simple as bloating or as scary/gross as C Diff, you need to try these probiotics. Especially the "Just Saccharomyces Boulardii"
