Hi, I wanted to weigh in on this discussion. After a colonoscopy in December of 2015, I ended up with C Diff. I also had a fecal transplant in 2019. I was free of C Diff for a long time. If I had to take a antibiotic, I also took Vancomycin and for about a week after antibiotics ended. I have no idea how, it came back with a vengeance June 2024. I tried Dificid, only gave me 7 days C Diff free. I was on Vanco twice a day, just to keep it at bay. My GI doc did a colonoscopy to verify that there wasn't anything else going on in my GI tract. I did do the Vowst. I finished the Vowst March 26, 2025. It's been a month and so far so good. I'm hopeful that it will continue to be a good. When I travel, I always carry Vanco, just in case. My GI doc does not advise probiotics. I had taken them for years. The person at Vowst advised not to take any probiotics for at least two weeks after the Vowst. I haven't taken any and I don't know if I want to start them again since there is so much back and forth about the effectiveness of them.
