MUST READ! lots of info below. Viable for making "yogurt". 1st batch is always weird, 2nd is dreamy
I use these tablets to make L. Reuteri YOGURT (ah hem, "cultured dairy product") as per the hundreds of YT video recipes, but most importantly as described by Dr.William Davis in Super Gut (as well as YT vids). This is what I happen to follow. I am sure there is discussion around better practices to achieve even greater CFUs. I havent ventured into that territory because if things get complicated, I may not bother. In mean time as I learn more, I use the original "recipe". MY container of tablets (purchased May 2025) is viable. NO ISSUES. Yes, DrDavis also now sells his own (very pricy) but this is what he originally recommended as do others. He didnt necessarily stop recommending it because there is a problem, he stopped because he came out with his own line! Though I will add that there have been some comments made by him and others that the product hasnt been consistent, and that the company wont talk to him. So take what you will of that info. I dont see needing any more anytime soon since I can make many, many batches from what I initially made. 1st pic is 1st batch. Chunky. Basically curds & whey. Good product. Can eat. Just not smooth. Totally norrnal for very 1st batch. Use a couple tablespoons to use in second batch (no need for the tablets) 2nd photo is the second batch. I made a 3rd and it came out same way. All good OK, the rest of the info is HOW TO MAKE l. Reuteri yogurt. Or at least this is how I make it. I included links to what I use. I am not naturally inclined to making stuff like this, but I find l. reuteris SO VALUABLE and helpful in so many ways, that I wanted to greatly increase what I was taking w/o necessarily having to take more capsules. I do both. I make yogurt now (really quite easy, and very little prep) and I still pop capsules. Nothing else matters if you dont have a good microbiome (it affects EVERYTHING in incredible ways). Taking probiotics (and prebiotics--very important, gotta feed these good critters), eating fermented food (if you can), and making healthier choices (as much as you can). If food and sweets obsessed, probiotics (l Reuteri, akkermansia, and gasseri help A LOT in that department. My food noise has turned off!!!!!!). -------------------------------------------------------------- -------------------------------------------------------------- WHAT I DO: SO, I made my FIRST BATCH using this lovely yogurt maker (can be set to 100* and 36 hour timer as per reuteri needs). --10 crushed tablets (crush as best as can. These tablets have a little pink in them so dont freak out) --2 TBS prebiotic fiber. I use

Noticeable support for digestion and gut comfort
I’ve tried a few probiotics over time, and this one stands out for how straightforward and effective it feels. After taking BioGaia Gastrus consistently, I noticed a clear improvement in everyday digestion—less bloating, less discomfort, and a more regular routine overall. What I appreciate is that it doesn’t feel harsh or overwhelming. The capsules are easy to take, and the formula seems well-balanced rather than overly aggressive, which makes it suitable for daily use. Another reassuring point is the research behind the product. Knowing it’s backed by years of study adds a level of confidence you don’t always get with supplements. Of course, results can vary from person to person, but in my experience this has been a reliable option for supporting gut health and maintaining balance. A solid choice if you’re looking for a probiotic that focuses on comfort, regularity, and long-term digestive support.

Happy pills
Remarkable. Oxytocin making machine. I'm an adult and took 5, the next day the feelings of wellbeing were obvious. Gave 5 to a family member who was staying at the hospital with her father who is on hospice. She was under incredible stress and felt like within about six hours she could feel the difference. Gave it to another friend, he too experienced more feelings of joy and happiness the next day. Follow the YouTube videos on how to use it to make 36 hour, high probiotic number yogurt. Worked great. Just keep in mind the first factual separate, but the second one will be nice and creamy. Both work great and cheap.

Yogurt miracle for digestive health
Makes the best tasting homemade yogurt! Healed my gut and regularity issues! Warning: you will have very loose stool for the first few days as your gut microbiome adjusts, but then after that its wonderful.

work pretty well for making l reuteri yogurt
I made a small test batch of yogurt and got mixed results. Two of the small containers did not ferment at all but the third one did and the yogurt came out pretty well. I think what happened was that the crushed tablets didn't dissolve completely and most of the powder stayed at the bottom of the mixing dish, so when I poured it into the first 2 containers not much of the powdered probiotic got in there. So overall I'd say the tablets work but you have to make sure you dissolve them completely into the half and half. I wish that they wouldn't use the flavoing, it gives the initial yogurt a bit of a strange taste.

The best probiotics to start making L reuteri fermented dairy (yogurt)
A must for making L-reuteri fermented dairy. I know some Dr. started making his own and says otherwise, NOW, but of course does, he has a big following and is making a killing. This is the original and has been used for years with wonderful, healthy, results. Separation of your "yogurt" happens for two reasons. 1) You aren't heating your milk to 180 degrees for 10-20 minutes and letting it cool off prior to making your L reuteri, or 2) You're cooking it for 36 hours and killing off all the good bacteria you added into it the first place. Mine usually sets up around the 18-hour mark. I got this information from a reputable nutritionist that has been making L reuteri for many years and specializes in fermentation of foods for gut health. These tablets are easy to use and smash up nicely. They smell a bit of citrus, but that doesn't come across in my finished product. They last a good long time, and I use 10 tablets for my starter batch, then make about 5 subsequent batches using part of my previous fermented dairy as the starter culture before starting from scratch for a whole new batch. So, I think the price is a very good value. My L reuteri turns out beautiful and delicious every time. I could not make it without these probiotics. They are simply the best.

Da die Tabletten teuer sind, bietet es sich an sie als Starter zu verwenden um Joghurt (bzw. Milchferment) zu machen. Zudem bekommt man so auch um vieles mehr probiotische Bakterien pro Portion (typisch 120 ml) im Vergleich zu einer Tablette. Die Fermentation mit diesen Tabletten gelang. Es passierte keine Separation zu Molke (flüssiger Teil) und Käsebruch (festerer Teil, Hüttenkäse-mäßig), sondern alles wurde schön homogen. Meine Zutaten: • 1 l H-Vollmilch (3,5 % fett) • 2 EL Inulin-Pulver (leicht gehäuft) • 10 Gastrus-Tabletten Weil es H-Milch ist, kann man sich das Sterilisieren der Milch sparen. Ich habe die Tabletten in einen Zip-Lock-Beutel gegeben und mit einem Hammer pulverisiert. Elektrische Mühlen sind angeblich schlecht für die Bakterien. Das Inulin habe ich extra in einer kleinen Schüssel mit ca. 4 EL Milch vermischt, um dort die Klumpen gut herauszubekommen. Wenn ein paar Klümpchen bleiben, ist es auch kein Weltuntergang. Restliche Milch und das Gastrus-Pulver in einen geeigneten Behälter gegeben und kurz vermischt. Die Mischung aus der Schüssel dazu, und alles gut vermischt. 36 h fermentiert bei 37°. Ich verwende einen Joghurtbereiter / Yogurt Maker. Dann in den Kühlschrank gestellt. Behälter, Deckel, Schüssel und Löffel (zum Umrühren) wurden zu Beginn mit kochendem Wasser (vom Wasserkocher) sterilisiert. Deckel sterilisieren, weil es bildet sich Kondenswasser an der Unterseite, welches von dort zurück in den Behälterinhalt tropft. Manchmal liest man, dass die Fermentation bei jemanden nicht startet mit den Gastrus-Tabletten. Es könnte sein, dass die Temperatur beim Transport zu hoch war für die Bakterien, was sich vermeiden lässt, indem man in den kälteren Monaten bestellt. Update: Der zweite Batch gelang auch. Ich habe alles gleich gemacht, nur statt den Tabletten habe ich 3 leicht gehäufte EL aus dem fertigen ersten Batch als Starter genommen.
