    Outcomes Body odor changes after FMT?

    -do you get the same body odor as your donor after a lot of fmts? or is it more of a temporary effect that's gone as soon as you finish the fmts? I have not smelled the body odor of any donors as I do not know any of them personally. I also haven't noticed major shifts in my BODY odor after FMT...

    Just last night I posted a very recent (in fact, not yet formally published in a journal) paper in the "Microbiome studies, news, media" section that you might really like to read. You ask a lot of questions about the microbiome and how it functions biochemically, that's what this paper is all...

    Question GutID Microbiome Test

    In what way were you not impressed with Viome's results? Did they indicate your gut was "normal" despite you feeling very poor? That's how Thryve (now Ombre) was for me. I read about GutID and it seems the chief advantage they claim is that they identify bacteria down to the strain level...

    Sources Comparing commercial FMT providers

    I mean that there is no way to compare PROVIDERS without receiving data from people who have tried more than one. Saying merely that of five people who ONLY tried Microbioma, for instance, only two improved, while of four who ONLY tried Gezonde Darmflora, all four improved, doesn't necessarily...

    Causation Helicobacter pylori CagA+ strains modulate colorectal pathology by regulating intestinal flora (Feb 2025, mice)

    It looks like at least the abstract was run through an automated translation software of some kind, because some incorrect interpretations of terms have been added. In particular, I assume that "F/B ratio" in the original paper is referring to the Firmicutes/Bacteroidetes ratio, but the software...

    Causation Very interesting paper about metabolic roles in the gut microbiome (August 2024, preprint only, human) A widespread hydrogenase drives fermentative growth of gut bacteria in healthy people

    I was excited to see this paper a little under a month ago, as it confirms some things I've been using as a working assumption for a long time, yet never actually seen any empirical evidence for. The paper is only a preprint (i.e., an article that hasn't made it into an actual journal yet) now...

    Sources Comparing commercial FMT providers

    "Other people make brief comments here and there"--that gives no basis to evaluate the overall success rate of any provider. What you really need is to look for people who have tried more than one provider. Clearly there are people for whom finding the right provider and/or donor is MUCH harder...

    Early development Maternal allergy status, infant birth season impact milk microbiome of mothers (Dec 2024, n=196) Maternal Allergic Disease Phenotype and Infant Birth Season Influence the Human Milk Microbiome

    Interesting! So maybe it's time for a "microbiome zodiac" lol. While I'm sure that environmental bacteria vary significantly across the seasons, I would have thought that the human host environment would have buffered a lot of that, especially in modern Western cultures where food...

    Blog The FDA and FMT regulation, part 2. (Jul 2024, HumanMicrobes.org) I met with the FDA. Here's what I shared with them, and their response.

    What I mean by tone is this... in a number of your posts, you come across as if you believe the following: 1. The FMTs you have sold are so much superior to FMTs from ANY other provider, that anyone who uses a different provider is wasting his or her time 2. Building off point 1, you have...

    Human Microbes Extreme Success From SD_ES_2015 For Severe Anxiety, Depression, and IBS

    The way I read the OP, I understood it that this is the most compatible donor of the four that he/she has tried, BUT even then, it STILL required a combination of thawed AND unthawed to be dramatically effective.

    I guess it's just a bad picture then. Hopefully the same goes for his general tone about other people, the state of the world, and the role of his own work in the whole thing. It's possible he mostly posts here when he needs to rant.

    It sounds like whoever you used was a poor match donor for you. The one donor I've tried who made me worse, it was a similar thing, it greatly flared my mental health issues (whereas good donors improve them--and my best donor, from OpenBiome, temporarily got my mental health the best it had...

    I don't know if it's the beard by itself, or the general vibe that the entirety of your appearance gives off.

    Autologous Autologous type-3 FMT (dark brown), Floraphage

    By the way, someone in a FMT group just mentioned this clinic in Portland, and I see they do autologous stool banking: https://drcarmencampbell.com/aboutme/. So this is a definite option if you want to do what I was saying above (save some of your microbiome prior to going on antibiotics). I...

    Autologous Autologous type-3 FMT (dark brown), Floraphage

    The opposite is true--autologous FMT will NOT restore critical species or strains that are entirely missing (unless the stool is collected before whatever stress--e.g. antibiotics--causes them to go extinct in your gut). Yes this concept IS correct. Each species of bacteria has certain...

    I'm surprised as well that Bernie Sanders was dismissive of FMTs (or at least, that he was MORE dismissive than the average politician--even if ALL politicians almost HAVE to be dismissive of most things in order to make use of their limited time). He seems like a remnant of the 60s...

    Autologous Autologous type-3 FMT (dark brown), Floraphage

    In my opinion, FMT is FAR too much of a gamble to be valuable if you have no health issues! In other words, it isn't something you do that's comparable to taking a bit of extra B vitamins or adding more leafy greens to your diet. Yes, for those of us with intractable health issues it can be an...

    Autologous Autologous type-3 FMT (dark brown), Floraphage

    Yes, this is VERY different. Autologous FMT taken from before one's current health issues started is definitely promising. In fact, this might be even MORE likely to work than FMT from an unrelated donor, whose microbes may not be compatible (in other words, that person's "normal" might not be...

    Donors FMT - good Idea for my circumstance? Plus list of donor possibilities

    What I meant was, based on his own self-report his best donors were toward the beginning of his journey, which means his success declined over time. I do not think that this is an inevitable consequence of more FMTs, but it doesn't support a claim that he is getting better at picking helpful...

    Donors Smelly donor stool

    I tried two new donors over the past three months--one male, one female, both teenagers, from the same provider. And both had quite smelly stool. I will report in full about them soon, once I know better how I did with the better of these two long-term. The female donor's stool also worse of...

    Donors FMT - good Idea for my circumstance? Plus list of donor possibilities

    While he MAY have gotten better at avoiding truly BAD donors, keep in mind that his two most helpful donors of all time were both among the first four he tried, yet he's tried around 15 of them by now. The next two most helpful were interspersed among 10+ who didn't make decisive differences. So...

    Autologous Autologous type-3 FMT (dark brown), Floraphage

    It's unlikely that taking your OWN microbes will help you in any way. Whatever microbes you have when your stool is the color/consistency you are aiming for are still in there when it changes, just in different proportions. Diet is causing shifts in the balance, and will still do so just as much...

    Suppose that the gut/brain axis is as important (in psychiatry) as the peer-reviewed literature seems to indicate. Why then isn't fecal transplantation an extremely famous and celebrated psychiatric treatment?

    It's also a 5-HT2C (one of the serotonin receptors, that plays a role in limiting the effectiveness of SSRIs) antagonist. There are multiple fates of tryptophan--being made into protein, acting as a NAD precursor, etc. 5-HTP can ONLY be used to make serotonin and melatonin. Provided that's what...

    FMT Openbiome Sep-Dec 2024 updates. Distribution will cease on Dec 31, or when their IND Phase 2 protocol is cleared to proceed.

    Interesting, I thought they had stopped shipping back in 2021 as you'd said. Not that it matters for most of us who don't have C. diff. I will definitely consider writing to the FDA, telling them about my excellent experience with FMT from OpenBiome (which addressed much more than just C. diff).

    Have you tried any of these other methods and had them actually work? It seems not, otherwise you would have gotten one of the good donors to "stick". If they don't work, then why use them??

    Procedure FMT implant advice/conundrum (clinic vs DIY)

    I'm guessing you're not in the United States, judging based on the clinics and suppliers that are available to you. Human Microbes was the only US supplier for DIY FMT, and they are no longer shipping, which means now there are zero based here--and no clinics offer endoscopic FMT treatment for...

    I have to wonder if the majority of people, legislators included, consider the main roadblock here to be scientific/medical, rather than legislative. In other words, they think that we first need to figure out the optimal way to technically carry out a FMT (including, but certainly NOT limited...

    Smell and microbiome

    Do you mean the smell of your stool? or the smell of your skin/sweat? Nearly all "sulfur smell" comes from the microbiome--the sulfur-containing amino acids that make up part of our own cells don't smell strongly like sulfur, that requires that bacteria break them down into smaller, volatile...

    What do you think is best? Something like vancomycin? Before I received the FMT that ended up being most helpful for me, I indeed took vancomycin for more than a month. In my case I had to, because I had active C. diff and couldn't get in for a FMT before about 1.5 months after my positive...

    Human Microbes Trial of glycerol-preserved UT-AW-1998 (Human Microbes) for gut pain, food intolerances, and cognitive/neuropsychiatric symptoms

    This is a follow-up to this experience, which I previously promised togive once more time had passed since the FMT.

    Phages are part of the (normal) microbiome, so they're not by themselves the cause of dysbiosis or any disease. The cause of dysbiosis is essentially always either 1) excessive antibiotics, or 2) an infection of some kind (many people apparently get IBS after a bad bout of food poisoning). Some...
