    FMT The Super-Donor Phenomenon in Fecal Microbiota Transplantation (Jan 2019, review)

    Comment from a previous thread: Another user mentioned that this should be common sense, which I agree with, and have been surprised at the amount of people arguing against it. Personally I would think it would also be common sense for the universities doing FMT studies and other microbiome...

    FMT The Super-Donor Phenomenon in Fecal Microbiota Transplantation (Jan 2019, review)

    https://www.frontiersin.org/articles/10.3389/fcimb.2019.00002/full An important paper to have submitted here. Unfortunately, the authors of this review didn't bother to attempt to find a super-donor for their FMT trial...

    FMT Fecal Transplant From The Rock Causes Mysterious Side Effects in Man (Oct 2025)

    https://the-peel.com/article/1723/ This doesn't seem to be a real story. See their "about" page: https://the-peel.com/about/ Their bluesky says "on the mission to deliver news before it happens".

    Sources I am considering going to IPPM clinic to do an FMT. Would you do it?

    The wiki has a section on them: https://humanmicrobiome.info/where-to-get-fmt/#ippm-clinic No, I would not use them.

    Worse after FMT

    Extremely unlikely. This is why I've spent the past 10 years warning people about using low-quality donors, and the poor donor screening & selection at hospitals, clinical trials, and stool banks.

    Worse after FMT

    In general, it seems like the only way to recover from a bad FMT is to do FMT from a better donor. Where did you get the FMT? From a hospital, using their donor? They did it for IBS? Was it part of a clinical trial?

    Shipping FMT within Canada.

    Yes, I think Fedex is the easiest option.

    FMT Shaping the future of probiotics, live biotherapeutic products, and fecal microbiota transplantation: 30 scientific recommendations from the CHINAGUT Conference (Oct 2025)

    https://onlinelibrary.wiley.com/doi/10.1002/imt2.70083 This is incredibly depressing. Not a single mention of donor quality, and they're promoting the failed & inadequate stool bank model.

    FVT Effects of lyophilised faecal filtrate compared with lyophilised donor stool on Clostridioides difficile recurrence: a multicentre, randomised, double-blinded, non-inferiority trial (Sep 2025, n=138) "supporting the crucial role of live microbes in mediating clinical efficacy"

    https://www.thelancet.com/journals/langas/article/PIIS2468-1253%2825%2900190-6/abstract A previous study indicated that a sterile fecal filtrate was effective for C. diff. https://humanmicrobiome.info/fmt/#sterile-fecal-filtrate This study says otherwise.

    Donors Does stool donor sex and age matter? Are there differences in receiving fecal transplants (FMT) from male vs. female donors? And different age groups and enterotypes? Donor matching

    If you mean studies supporting your claim, you need to cite them. As you note, I already commented on that anecdote and debunked the claim.

    Donors Stool donor with family history of colon cancer

    What criteria? https://humanmicrobiome.info/cancer/ You can see there is plenty of basis for concern that you may "transplant a biome that supports the development of cancer". It's largely unknown. FMT is all about risk vs reward, and family history is an added risk.

    Diet/nutrition Best probiotics, vitamins, and minerals for J-pouch to reduce BM frequency

    Did you review the probiotic guide? https://humanmicrobiome.info/probiotic-guide/ FMT would be the most effective option, but it's not going to be widely available from safe & effective donors unless people start taking action...
