I'm curious: I've always suspected 'probiotics' are ineffective, like scattering a few daffodil seeds into a field of weeds. Either not a significant quantity to compete, or just 'food for bugs' which feeds everything indiscriminately.

as someone with plenty of gastrointestinal issues, probiotics are a godsend

curious to know if you have ever done a double blind test to determine if it's just a placebo effect?

Methodologies aside, people really do have to take the majority of their personal health into their own hands. Most folks only see a doctor for a few hours in an entire year (much of that just sitting in reception) and rely on OTC self-medication for most minor issues.

There's a lot of criticism around people that self-experiment or self-diagnose, and it is indeed a potentially very dangerous practice, but the expense and fallibility of doctors can sometimes leave little alternative.

One example of this is Nicholas C. Zakas's recent account[1] of his discovery that he is afflicted by Lyme disease, has had it for the last 15 years, and was frequently misdiagnosed with everything from depression to having an eating disorder.

The point is, regardless of education, nobody cares as much about your health as you do. Doctors deal with hundreds of patients, you get to focus on just one.

Big question for you.... did you do anything prior to FMT to alter your flora?

I work with a major researcher in FMT and actually act as a donor so I know a little about this. Patients receiving FMT typically receive a short course of vancomycin to rid the gut of bacteria (or as much as possible). It's like starting with a clean slate. Your gut is then more readily able to accept the donation. Without the vanco (or other abx) you are basically just throwing shit at more shit and hoping it sticks.

I think your results would really change if you had done this through a doctor and had a bit of abx prior to FMT (or even just an enema).

I haven't but I also am always in a lot less pain when I take them. Invariably I start to have problems when I forget to keep taking them. It got to a point when every time I complain about stomach pain, a co-worker asks if I am taking my probiotics and the answer is always no.

Is this satire? Did he really have a friend poop into his butt on whim?

FMT is at least a real process, see http://en.wikipedia.org/wiki/Fecal_bacteriotherapy . I don't think you quite captured how it's done in practice, though.

It's a real practice in hospitals with trained medical doctors. Not "in my apartment with a close friend."

The difference is well within the variation you'd expect from multiple samples, extraction, PCR, sequencing, day-to-day. Also, you're probably better off trying to alter your gut microbiome through ingestion of probiotics. Source: I am a PhD student research the human gut microbiome in connection with autoimmunity and have processed thousands of these samples using the exact same methodology as uBiome.

Do we know specific pro-biotic species that have been found to be significantly more beneficial than the rest? How do we know? Does "pro-biotic" refer only to beneficial prokaryotic organisms or are there known beneficial "pro-biotic" foreign eukaryotes?

There are some eukaryotes, yes, e.g. Saccharomyces boulardii.

This is probably an unpopular opinion but it seems to me that "SV culture" has taken to fetishizing "health hacking" with little to no medical training/background or support. See the recent SV craze with "health informatics hacking". They're putting a shiny, appealing veneer over what amounts to homeopathy and random self-experimentation. Someone is going to say, "but they have all this data, like this guy from µBiom…

I really expected you to say that they were "polishing a turd"! [1] On the flip side, you have to admire people who are becoming actively involved in their health AND learning more about the basic functions of human anatomy. A long time ago, it was illegal to dissect cadavers and medical knowledge required committing a crime. Isn't it better for smart people (who in theory understand the risks) to be allowed to conduct even uncontrolled experiments?

>They're putting a shiny, appealing veneer over what amounts to homeopathy How is self experimentation equivalent to homeopathy? I don't get how giving a shit about your own health is equated so quickly with a specific nonsensical, pseudoscientific sham.

This may not be, but things like Soylent which claim to solve all your nutritional and health needs by drinking it, are the equivalent of homeopathy -- like say, drinking g tea made from the horn of rhino will make your virile.

I don't think you know what homeopathy is. http://en.wikipedia.org/wiki/Homeopathy will give you a clue. "Tea from the horn of a rhino" is possibly considered treatment in some places, but it is not homeopathy.

(Which is not my support of homeopathy - it's just that using the right term is important for discourse. It's important to distinguish between copyright infringement and theft, and it is important to distinguish between different forms of alternative -- that is, not scientifically proven -- medicine).

Ah the yeasts! I recently heard that middle-eastern ancients regularly rubbed old-bread on wounds to speed recovery. Probably more for penicillin mold, but maybe the yeasts were at play as well?
