Because consumption of the L. reuteri yogurt made with the ATCC PTA 6475 and DSM 17938 strains work by raising levels of oxytocin (in addition to local probiotic benefits on reducing H. pylori and acid reflux, for example, unusual for its upper, not just lower, gastrointestinal benefits), there are people who probably should not consume the yogurt..
Oxytocin is a multi-faceted hormone whose levels decline as we age, much as does growth hormone and other hormones. But, among its many varied effects is the potential for causing uterine contraction. That is why oxytocin is administered to provoke delivery of a term infant: it provokes uterine contraction to deliver the baby along with cervical relaxation. There are experimental non-human and yet unpublished data that suggest that oxytocin may raise estrogen levels in females. But, because of these potential uterine and estrogenic effects, there are people who probably should not eat the yogurt that boosts oxytocin. This includes:
- Pregnant mothers
- Women younger than age 45
- Women with a history of estrogen receptor-positive breast cancer
- Women with active endometriosis
- Women who are still experiencing menstrual cycles
The last item, menstruating women, is to avoid making menstrual cramps worse, i.e., amplifying the intensity of uterine contractions. (Interestingly, a couple of women taking the yogurt but still experiencing menses actually reported dramatic reduction in menstrual cramps, but that is insufficient evidence.)
That said, oxytocin when administered intranasally or injected, even at many times physiologic doses, has a long track record of safety with virtually no side-effects reported beyond occasional reports of excessive emotionality (e.g., crying too much at movies). So these are just precautions as we all embark on this fascinating adventure of boosting oxytocin levels, given its extraordinary youth-preserving potential that is being played out in experimental evidence and now increasingly in human evidence.
Just wondering why the yogurt? Does it work the same by taking just the probiotic?

Oh, my, now I’m upset after reading “Women with a history of estrogen receptor-positive breast cancer” should not consume. I had that type of BC 8 years ago. So sorry not to be able to experience the good effects of this yogurt. I suppose I’ll have to go back to my previous method of using a store-bought yogurt as starter. Very disappointed!
My experience with the yogurt: I started with a quart of half & half, the slurry made with 10 of the tablets. On my 4th generation, using 1 Tbsp of yogurt and 1 qt. of half & half, eating 1/2 cup daily. I’m 10 years past menopause and now experiencing uterine contractions. No known cancer of any kind. I don’t like the feeling of it so am going to stop consuming.
This warning NEEDS to be added to EVERY post you have on the topic PLEASE!!!
It would have saved me from purchasing products that I can’t use now!
I’d like to mention my own experience here b/c I too expected to have positive results from making my own L-reuteri coconut yogurt. First, I’ve made and consumed cow’s milk yogurt for many years – no sugar added, and about 10 yrs ago, using raw, local, unpasteurized milk that I did not_ heat to high temps before inoculation. It was delicious. I took grains and all processed foods out of my diet after reading Wheatbelly, The Wahl’s Protocol, and Fat for Fuel and Gary Taubes. I’d already figured out what sugar did to me and never purchased or consumed foods with added sugar as recommended by Yudkin years ago. I developed a persistent rash on my torso and finally realized it was caused by milk protein. A tiny cube of an Irish cheddar sample at the grocery store brought back the rash. So now I’m reading and rereading Undoctored. I love yogurt and have made my own coconut yogurt successfully with L-reuteri and I have SIBO with all of it’s accompanying symptoms including IBS and I’m really bummed… Obviously I still have some work to do regarding my leaky gut. So I’m heading over to Amazon to buy some 12 strain probiotics. FODMAPs diet website says they are in yogurt. Inulin is full of them too, so I recommend not_ using Inulin if you are making L-reuteri yogurt. I’ve made a batch of non-L-reuteri (inoculating with high end probiotic capsules I keep in my fridge) coconut yogurt using tapioca starch and pectin like Coyo does and it was very similar to Coyo coconut yogurt – this is the only thing I’ve added to my diet recently and I’m really struggling. And I just thought of something else. I have those expensive probiotic capsules in my fridge, unused, because they have caused me digestive upset in the past. I’ll keep looking for answers – soon to be 70 and at least happy that I got my figure and high school weight back 4 years ago after reading and following the protocols from the books mentioned above.
