I read Super Gut by W. Davis on vacation last week, ordered a yogurt maker and just finished making my first batch. I’ve had a lot of gut issues and food intolerances since I was on 50 days of levaquin after a body fluid exposure at work from a patient who had klebsiella pneumonia. It’s a long story but I’ve been dealing with the fallout from that since 1999. I’ve even considered FMT so I could expand my diet a bit again. I didn’t have celiac or oxalate (kidney stones) issues prior to the levaquin so I’m pretty sure it decimated my flora. Whew, sorry for the long winded tale. Probiotics have never helped enough so I’m hoping the 36 hour fermentation at 106 degrees Fahrenheit he writes about in the book is more powerful than store bought yogurt and probiotic pills.

Hello blsm, have you ever noticed any alleviation after taking the reuteri yogurt (which William Davis mentioned in his book), can you share your experience with us

I’ve been making my own L. reuteri for over three years now. It’s the best thing I’ve ever done for my gut health. I strain it to remove the lactose. I use semi‑skimmed UHT milk so I can skip the heating step. Every morning, I add over one cup to my smoothie.

I got a kefir starter kit on Amazon some 15 years ago (maybe more?), and I’ve been making kefir from nonfat milk ever since. I don’t know if it does anything for my health, but a lot of research seems to say it’s a positive, so I kept up with it. I find it amazing how long you can keep going with the same grains. Apparently there are kefir batches made continuously for generations in the Caucus region, so there’s a good chance these grains will outlive me - maybe I can put them in my will to some “lucky” recipient “Verified To Be In Working Order”.

Thanks for sharing, I am excited to make my own yogurt

But I have a problem, guys do you use a single strain of L. reuteri to make yogurt? Or do you mix other strains such as BB-12 or other strains with other benefits? I don’t know if adding other strains will compete with L. reuteri and make it difficult to survive.

I use a single strain of reuteri.

I did not personally notice anything. I feel like what helped me the most (besides rapa) was eating oatmeal most days and being mindful of fiber in general by including >800 grams of plants in my diet each day.

FWIW, in the instant pot yogurt group on facebook, for my cold start yogurt, this is the probiotic they recommend. I have used two other probiotics, and one of those also worked well, but the other, Pendulum glucose control, was a huge fail.

Oats are like a superfood for my gut I’ve found, most probably the beta-glucans. Watercress is also very well tolerated for some reason. If I’m making a spicy soup or eating another soup which has some adventurous ingredients, I always throw in a few oats as I know that can mitigate any potential negatives.

I use this strain for my yogurts. Works like a charm.

Yes, they recommend that one and it’s always worked for me. I do cold start in instant pot with boxed soy milk (single ingredient). They said to use 2 capsules.

Hope it works as well for you, too!

I’ve heard that Dr William Davis went to a new company Oxiceutics, he now sells a new strain called LRDR™ , he said that the new strain has better effect then the older one.

Actually, Dr Davis used to say that BioGaia is the best, but then commerce interfered - he now does promote and sell a new strain of L Reuteri;)

Anyone actually supplementing with postbiotics?

Butyrate, tributryin, propionate, urolithin A?

Davis claims his brand has higher CFUs. There is no mention of the particular strain, but I suspect it is the same strain as Biogaia’s. It is manufactured in Illinois. Agrees with the buy American sentiment. No danger of tariffs.

Dr. Davis has recently recommended a SIBO yogurt, with three co-fermented strains.

Also, a saccharomyces boulardii juice.

There is also a bacillus subtilis juice.

I do not know if it is the same strain as the subtilis used to make natto.

This video demonstrates how to make a probiotic juice using kombucha and juice to support gut health.

Key Points

  • Dr. William Davis and Dr. Sandra Scheinbaum show how to make a simple probiotic juice at home.
  • The juice uses kombucha (specifically one containing Bacillus subtilis) and a juice without preservatives.
  • The goal is to support the gut microbiome, boost digestion, mood, and overall health.

Step-by-Step Instructions

  1. Choose Your Ingredients:
  • Select a kombucha product that lists Bacillus subtilis as an ingredient.
  • Pick a juice with no preservatives (no potassium sorbate or sodium benzoate), as these can kill beneficial microbes.
  1. Prepare the Juice:
  • Pour out about half a cup of juice from the bottle to make room for the kombucha.
  1. Add Kombucha:
  • Add 1/4 to 1/2 cup of the kombucha containing Bacillus subtilis to the juice bottle.
  1. Mix and Ferment:
  • Cap the bottle and gently agitate to mix.
  • Loosen the cap to allow carbon dioxide to escape during fermentation (to prevent the bottle from exploding).
  • Let the mixture ferment at about 90°F (32°C) for at least 60 hours. You can use a sous vide, yogurt maker, or a warm spot in your home.
  • Taste the juice after 60 hours. If it’s still sweet, ferment for another 12–24 hours. The finished product should have little to no sugar.
  1. Consume:
  • Drink 1/4 to 1/2 cup once or twice a day.

Additional Tips

  • Juices with pulp (higher in pectin) are preferred, as pectin is a good prebiotic fiber.
  • Bacillus subtilis is highlighted for its broad-spectrum antibiotic effects and ability to colonize the small intestine.
  • Always ensure the cap is loose or use a venting cap to avoid pressure buildup.

This process creates a probiotic-rich, low-sugar beverage that can be easily made at home to support gut health.

We make and eat lots of fermented foods like yogurts, Kefir (from grains), sauerkraut, sourdough, etc. and now even cheese!

For a precise fermentation temperature we use a sous vide heater/circulator and we make yogurts by the gallon as mentioned here: How to Reverse Skin Aging - #1072 by cl-user

I found it difficult, if not impossible, to find good yogurts in the US so the only solution is to make them, which is incredibly easy, and allows to test various bacterial strains.

Kefir from grain is the most complex of all in terms of bacterial and yeast strains diversity and, as mentioned by @CronosTempi, they live in a symbiotic harmony forever if you take care of them. It’s like sourdough in fact, you need to feed them. Kefir which is store bought or from a sachet are made from a very limited subset of the strain.

Plenty of diversity for sure! That’s why Kefir grains are so much better than Kefir ferments in sachet.
For instance the Yogourmet Kefir starter only has these: Lactococcus lactis, Lactococcus cremoris, Lactococcus diacetylactis, Lactobacillus acidophilus, Saccharomyces cerevisiae, Kluyveromyces lactis.
