Skim A2 pasteurized cow milk -
I use pasterized or ultra pasterized milk. For me, the idea is to have only the reuteri bacteria fermenting. Other strains of bateria in raw milk may also grow during the process and compete with the reuteri.

@LetTheRedeemed said in L. Reuteri:
@Amazoniac yeaahhh... I had some concerns too, because of some old posts by Georgi...
Well, the study below finally provides direct evidence that Lupus can be triggered by a bacterial strain commonly found in many probiotic products - Lactobacillus reuteri.
Lactobacillus reuteri - WikipediaIn light of the continuously accumulating evidence that bacterial overgrowth in colon has a role in virtually all chronic diseases, I would be very wary of exogenous supplementation unless there is proven colonization with a much more dangerous pathogen.

https://www.genengnews.com/news/microbiome-changes-through-diet-may-help-ease-lupus-symptoms/“We dissected, molecularly, how diets can work on the gut microbiome,” said senior author Martin Kriegel, M.D., Ph.D., associate professor adjunct in the department of immunobiology, Yale University School of Medicine. “We identified a pathway that is driving autoimmune disease and mitigated by the diet.” The paper, A Diet-Sensitive Commensal Lactobacillus Strain Mediates TLR7-Dependent Systemic Autoimmunity was published recently in Cell Host & Microbe. The team first identified the bacterium, Lactobacillus reuteri, in the gut of the mice that triggered an immune response leading to the disease. Specifically, in the Toll-like receptor 7 (TLR7)-dependent mouse models of lupus, L. reuteri stimulated immune cells known as dendritic cells, as well as immune system pathways that exacerbated disease development."
###### this sux cuz I want a quick fix for my infectious problems
I'm not beyond looking for some evidence that results can be safely found in moderation.
I agree with Mauritio and don't find these issues too concerning, but it's good to know what it's doing. Lactate production may have a temporary antimicrobial effect, which would help to eliminate pathogens. If for some reason it disturbs the gut afterwards, the person can try to recolonize it with other microbes. Lactate can also be cleared locally before absorption.
- Lactate is mainly fermented to butyrate by human intestinal microfloras but inter‐individual variation is evident
- Lactate-Utilizing Bacteria, Isolated from Human Feces, That Produce Butyrate as a Major Fermentation Product
- Lactate- and acetate-based cross-feeding interactions between selected strains of lactobacilli, bifidobacteria and colon bacteria in the presence of inulin-type fructans
- Impact of pH on Lactate Formation and Utilization by Human Fecal Microbial Communities
- Rates of production and utilization of lactate by microbial communities from the human colon
- Microbial lactate utilisation and the stability of the gut microbiome
- Intestinal Short Chain Fatty Acids and their Link with Diet and Human Health
- Metabolism Characteristics of Lactic Acid Bacteria and the Expanding Applications in Food Industry
I think that a greater concern would be the competition for vitamins that occur in the gut and eventually depleting those that are already low. Stuffing yourself with probiotics may call for temporary use of topical vitamins.

@Amazoniac are you aware of any vitamins that L. reuteri consumes?
I only recall reading about it producing B12, but other than that I haven't come across anything like that.Dare to think.
-
@Amazoniac interesting. Thank you much brother.
Funny, I’m quoting these old rpf threads to y'all, but y'all were in them lol @Mauritio

L. Reuteri 6475 potently increases the serotonin Transporter SERT, which picks up serotonin and thereby reduces its availability.
They also showed that it reduced colitis in a rat model and lowered inflammatory cytokines like IFNy or TNF.https://pubmed.ncbi.nlm.nih.gov/34550056/
DSM 17938, the other strain in Bio Gaia's Gastrus, also decreases serotonin. In this case directly.
Interestingly the effect took a while to show,but after that inertia, the longer they took it the more it lowered serotonin.
-
@Mauritio have you increased your dose bud? (From a fourth of a tablet)
How much is everyone else taking? I know @Amazoniac is eating the yoghurt, is anyone else doing this too?
-
@Ismail yes I increased to 3/4 of a tablet and will increase further soon.

@Mauritio said in L. Reuteri:
@Amazoniac are you aware of any vitamins that L. reuteri consumes?
I only recall reading about it producing B12, but other than that I haven't come across anything like that.I don't, but it's something to consider if the person starts to notice negative effects. The problem is that the bacteria can't be considered in isolation, what matters is the result of its addition. L. reuteri might consume a vitamin, but promote the growth of producers that make up for it. Rate of production also matters: there can be substitution for consumers that use up little of it in relation to the previous colony. Competition is likely harsher between microbes than with the host. Therefore, if someone doesn't notice gut issues, gross depletions might not be a concern for this individual.

L. Reuteri is part of our historical gut microbiome. It has always been present in all mammals. In recent decades, it has become very hard to find in the human gut. The new normal is not to have reuteri present in our gut. It is thought that our modern lifestyle (highly processed foods, antibiotics, the over use of herbicide and pesticides, improved hygiene, chlorinated water) is the cause for this loss of diveristy in our microbiome.
Restoring reuteri is a hack for increasing our testosterone levels. It seems that it is simply restoring our testosterone levels in the direction to the levels to what they were for hundreds/thousands of years.
-
@Amazoniac I noticed some transient vitamin B2 and biotin deficiency symptoms.
Although I suspect that's more due to killing the bacteria that produce those vitamins via reuterin. -
In this study another L. Reuteri strain 36301, caused a Testosterone increase of about 250%, in males that is. In females it caused shinier hair and skin and no testosterone increase.
It also reduced weight gain during aging and the inflammatory cytokines TNFa .In the OP of this thread the testosterone increase was dependant on IL-10 , while in this study they did not find a difference in that marker, so there has to be another mechanism of action.

Results: In glucose-tolerant volunteers, daily administration of L. reuteri SD5865 increased glucose-stimulated GLP-1 and GLP-2 release by 76% (P < 0.01) and 43% (P < 0.01), respectively, compared with placebo, along with 49% higher insulin (P < 0.05) and 55% higher C-peptide secretion (P < 0.05). However, the intervention did not alter peripheral and hepatic insulin sensitivity, body mass, ectopic fat content, or circulating cytokines.

Kefir’s hidden gem: the health benefits of l. reuteri
Besides kefir, L. reuteri can also be found in other fermented foods, such as:
Sauerkraut
Kimchi
Kombucha

L. Reuteri protects from ionizing radiation
L. Reuteri (KCTC 3594 and KCTC 3678) should help with acne via killing acne causing bacteria.

@AinmBeo
I made this yogurt. It’s mild, I like it
How much do you eat of it? Since I read about some concerns maybe I should just try it out first?Also, do you use the whey for anything specific?
-
@happyhanneke
I have 4 oz a day.
I dump the whey and lactic acid. -
Tryptophan can go down the kynurenine, pathway, the serotonin pathway or the indole pathway.
L . Reuteri increases Tryptophan metabolism into the indole pathway, which lowers its availability for the serotonin pathway.
Not only that, the metabolites of this specific pathway have anti-inflammatory effects. They treat experimental colitis.
One even acts on the pro-metabolic PXR , similarly to pregnenolone or progesterone."As expected, the expression of Pxr (also known as Nr1i2), a receptor for IPA [41], and PXR target genes Ugt1a1 and Cyp3a11 increased markedly in the colon of DSS-treated mice in response to L. reuteri (Fig. 1E)."

@Mauritio I have a lot of thoughts about these results because what if actually milk. Most people take L. Reuteri through yogurt, so...maybe milk is more responsible than the strain.
Also, in the case where someone takes a probiotic pill with it in there, what is the difference between people who consume dairy alongside it or across the day versus people who don't...
I took homemade L. Reuteri yogurt before peating while on carnivore. It didn't really improve much for me during that time. I enjoyed eating it though in comparison to all the meat that I was eating.

L. Reuteri increases Vitamin D. Maybe by increasing cholesterol conversion into vitamin D since it also lowers cholesterol.
"L. reuteri NCIMB 30242 increased serum 25-hydroxyvitamin D by 14.9 nmol/L, or 25.5%, over the intervention period, which was a significant mean change relative to placebo of 17.1 nmol/L, or 22.4%, respectively (P = .003)."
