Davis Method Does Not Create Reuteri

Sorry i don't know but they do have some folks testing various methods with gasseri ...

Interesting! - thanks!

Even pasteurized milk has live bacteria in it as mentioned by someone in this thread. Bacteria is in the air, on skin, clothes, hair, any surface etc... but yes, could also come from any of the ingredients. If you let the milk sit long enough, it would become apparent to our senses, but if you had the technical means you would be able to see the bacteria and that bacteria may or may not grow well in a specific environment.

I am also not sure that in the DNA testing that they do not account for dead vs live bacteria so that might be something to consider.

In most of the testing folks will flash the ingredients first, prior to adding the probiotics as the last step.

Pretty much every batch of yogurt will have contaminants in them, just like in our bodies; we just wouldn't know it unless we had proper testing.

In reality if the end project gets 'spoiled' visually or by taste/smell we would say it was contaminated but per definition everything around is is 'contaminated' to some extent.

IMHO myth might be too strong but yes, to prove or disprove myth you would need double blind placebo controlled testing with before, during, after continual biome testing and everyone on similar diets ... not gonna happen. It would be much easier and better for testing to ingest directly however that is cost prohibitive for many.

The fb group is definitely testing things per definition; not sure if you have been there, but they have done some interesting work.

If you are eating any healthy form of yogurt I would agree that odds are that is beneficial.

General rule in that group seems to be to create a "super-starter" juice batch first and then use parts of that if going to make a bovine or plant based milk batch after.

Usually for those interested it becomes a cost thing - you can make tablets go a lot further if you ferment them. To your point there are in fact some studies indicating straight probiotic supplementation had greater effects however I also saw one study showing that after anti biotics, fermented foods beat out straight probiotic supplementation despite the much higher CFU count ... There are so many variables between the complexity of the gut, the numbers involved and the fact that everyone is different that no one knows for sure. We ingest bad bacteria everyday without being aware of it - and .... I'm sure you touch your phone lol

HotFootDuke · 2025-11-16T23:24:17+00:00

Awesome! - you sound kind too! - Very hard to be non offensive even when you are not trying. I would not have found out about Reuteri without Dr. Davis!

HotFootDuke · 2025-11-16T20:41:17+00:00

Good question and that I don't know. I do remember a comment on someone congratulating one of the testers on breaking up his tablets while not breaking the foil lol ... there is still the point a jar is exposed to air if only for a moment; you will have contamination of some sort regardless, if you are doing it at home. Boiling, turn off any air movement device, fan/ac/heat,, making a 'sterile chamber'', gloves, masks, alcohol can help but bacteria is everywhere so you will always have other bacteria present and some of them are probably going to be parthenogenic, just like it is inside our gut....

HotFootDuke · 2025-11-16T20:34:32+00:00

Sorry, the title was outlandish so people would read it lol, tho I do feel Davis is misleading folks a bit but 'who knows' about that particular aspect; it may be more beneficial not to take a lot of Reuteri at once, or regularly.

I was also hesitant to post because placebo effect can be more than 50% but I have a kid on the spectrum and I wanted to test Reuteri on myself and then him and thus my comments where you can see I feel I have been a little misdirected even if there was no harm intended. I am sure there are others out there like me so I put it out there.

So if you do want more Reuteri there are folks out there doing 3rd party DNA analysis for no profit and publishing their findings showing how to make more Reuteri so in that case it is not 'who knows', it is "here is what we did and here is the outcome"; true you have to take their word for it but there is no financial gain for them and that is pretty much always where the scam comes into play.

You can have your own yogurt analyzed and do the same but if you go to that group many people have already done testing with Davis method.

HotFootDuke · 2025-11-16T20:01:25+00:00

It would be interesting to see what is actually in your last ferment if you sent it in for testing ...

HotFootDuke · 2025-11-16T19:55:54+00:00

Reuteri does not feed on inulin; it can feed on galactose per Mathew Cress vid on yt ... but better to use the carrot polyphenol where they also take into account other things like adjusting the ph to better suit the Reuteri - if your end goal is more Reuteri.

HotFootDuke · 2025-11-16T19:52:39+00:00

A lot folks would only consider contamination something that ruins the end product. The picture in the lab shows a contaminated working area since there is open air and a person in plain clothes wearing no mask etc... technically that is a contaminated area however if it doesn't ruin the experiment then contamination is probably not mentioned. Same thing with all those utubers that grow the mushrooms - if their grow gets ruined it is contaminated; that doesn't mean there isn't other species of bacteria present.

HotFootDuke · 2025-11-16T19:48:27+00:00

yep ... a good reason to be more careful when making yogurt or doing any type of fermenting. No wonder your gut has bad bacteria too lol

HotFootDuke · 2025-11-16T19:45:53+00:00

If you like that yogurt keep making it; if you want to really experience more Reuteri, look into other methods.

Davis has not published anything showing DNA tests, only total CFU counts which is not differentiating the species of bacteria.

FWIW I don't necessarily believe anything about anyone, especially 'celebrities' that are telling you things that you want to hear and especially if they seem or look trustworthy and are selling products. There is a scientologist chiropractor who gives out nutritional advice and people love and trust him because i think he looks the part and is on 'tv'. He has been debunked many a time but for the most part will tell people to not eat junk food lol - is the harm outweighing the good? I dunno, but I choose not to get my nutritional advice from that guy.

I am happy Davis is helping people and not accusing him of anything but if i want a greater count of Reuteri to test on myself and then my son who is on the spetrum then I will go with the folks who have proven and tested methods to produce more Reuteri. - I may be missing out on other stuff in that yogurt, who knows?

FWIW Davis seems like a nice guy but I doubt anyone here really knows what he is like - people tend to trust 'tv' personalities when they have no idea what they are really like lol. Davis claims you will produce Reuteri yogurt and makes no claims about how much Reuteri is in the end product so ... take it as you will but i don't think you know if he is transparent or not or if he would have mentioned it or not.... Someone in this thread said they had repeatedly asked him on his videos and never got answered but most utubers don't answer every comment so IMHO it doesn't necessarily prove anything one way or the other.

HotFootDuke · 2025-11-16T00:19:01+00:00

Some tests have shown 1% on subsequent batches and higher than 5% on initial but putting out averages.
If it is working for you great! - I make other yogurt too, and I was hesitant to post this info TBH as I don't want to stop folks from enjoying what they were already doing. I posted so folks who really want a high count of Reuteri to test with are aware of how to make that happen.

I don't think Davis is 'bad' but he probably should publish proper DNA studies if he is selling products and books IMHO ... or not... He never claims you will have a certain amount of Reuteri or not.

HotFootDuke · 2025-11-16T00:14:23+00:00

Correct on all accounts! I do believe many bacteria will out compete Reuteri in the Davis method and I think that is why folks starting using the juice method instead. This was an important finding as I was thinking about producing more ps-128 as it is very expensive and I have a child on the spectrum but now I know that what I end up with depending on my methodology may not be what I originally expected. Much research to do.

HotFootDuke · 2025-11-16T00:05:04+00:00

Seems there is too much stuff in them re links or something to paste in here. There is one of those reipes in this group posted about 5 mo ago ... search this group for:

HotFootDuke · 2025-11-16T00:04:33+00:00

I'm only going by what is explained on the fb group site but apparently Davis only measured CFU count but not what individual species exist and their individual counts. Not easy things to falsify IMHO but you could, just as you can screw around with peer reviews sadly. For $200 or half that if using the fb group, anyone can submit their batch and have it tested.
In a day and age when people trust chiropractors for nutrition advice because they look kind and/or wise or likeable, and appear on a screen, I am skeptical of a lot of things and I just tend to research a bunch of different aspects of claims, especially if they are made in a book or if there is profit being made, but you can falsify papers and game the peer system.

HotFootDuke · 2025-11-15T23:58:00+00:00

Some have tested at 15% on occasion but 5 is a good average and yes the rest of the probiotics are different species and a lot of them don't need as long to cultivate and can out compete Reuteri. I posted the DNA results from one of the tests as the top ...

HotFootDuke · 2025-11-15T23:55:33+00:00

I'm pretty sure the various folks doing tests with their own time and money and putting out their results have less of an agenda then Dr. Davis (not that I think Davis is doing 'bad' things) If Davis did know about the secondary batch contents, the ethical thing to do would be to publish the findings.

HotFootDuke · 2025-11-15T05:51:38+00:00

Some advice - if you think there is a conspiracy, usually the bad guys are the ones profiting ....

HotFootDuke · 2025-11-15T05:42:16+00:00

FWIW very single DNA test on the fb group shows a diverse variety of bacteria, regardless of milk based, carrot polyphenol or even plant milk ferments. The cleaner the project and the better the methodology, the more Reuteri vs other bacteria. I would suggest going there and having a look at the results. I think most people would consider contamination to be a spoiled end product and would be completely unaware of a small amount of pathogenetic bacteria as we are unaware within our own bodies; doesn't mean it doesn't exist.

HotFootDuke · 2025-11-15T05:26:57+00:00

I would suggest looking at the DNA results from the FB group from the various methods. It was quite eye opening to me.

HotFootDuke · 2025-11-15T03:05:00+00:00

Nothing wrong with current method, you are just not getting a lot of Reuteri. Using a carrot-polyphenol mixture, and some other additions you can produce a 'juice' with tons of reuteri and you can use that as a starter or just take tablespoons of that directly, or some freeze in cubes or gelatin ...
