Review: 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 --Buy a container of full fat ultra pasteurized organic half and half (I use horizon that I get locally, I know wallyworld carries it. .....................Take 2 TBS from it, or a health splash. Add it to bowl of crushed tablets and inulin. Mix well. Then add rest of container to the bowl. Stir well. DO NOT USE blades (ie mixer). Will slice up their little bodies. MAKE SURE your environment is as clean as possible. ie, hands are pristine, yogurt containers and lids are clean and dry, as well as yogurt maker. DOnt be touching hair, face, sneezing, have a fan going or anything. Pour into your yogurt containers. I put lids LOOSELY on them, place carefully in yogurt maker. Then I add enough water to reach the contents of the yogurt jars. Maybe a hair above. Put lid on. Set yogurt maker to 100 degress Fahrenheit and 36 hours. I like to have this ready to go at either 8-9 am or 8-9 pm, so that way 36 hours later, I am attending to it at either 8/9 pm (if I initially put in in the morning) or 8/9 am if I did it at night to start. DONT be like me, and get fired up to do it in the middle of the day, then 36 hours later I am dragging myself out of bed in middle of night to put the containers in the fridge. You do NOT wan the yogurt to just sit there. OK, SO-- FIRST BATCH most likely WILL NOT be a creamy dream. It will MOST LIKELY be half liquid and half chunk of firm chunky mess. Smell it, try it. Should be pleasant. No off colors (white and cream, maybe hint of creamy yellow). CONGRATS-- you successfully made CURDS AND WHEY! This is delightful. DO NOT THROW OUT. In fact, save some as it is VERY VIABLE for your next batch. Eat it, drink it whatever. The "curds" are like a dry cottage cheese, or a mild feta. Eat as is or smear on some toast. As for the liquid, go ahead an drink it or add to oatmeal or smoothies. AGAIN, do NOT use IN the blender. Just add to your smoothie at the end by stirring in. OK, so that may seem disappointing, but that is the norm. You have a robust batch of happy L. Reuteri bacteria. Very healthy. NOW, do this process again, EXCEPT, there is NO need to use more tablets. Just use 2 generous tablespoons of the curds and whey (can be one or the other or mix of both. I like mix of both). So, 2 tablespoons (or so) in a bowl. again, 2 Tablespoons of prebiotic fiber (ie Inulin) again add a healthy splash (about 2 tbs) of half and half stir well. Then add remainder of container of half and half. Stir Pour into (very clean, dry) yogurt containers. Put lids on loose. Place in (very clean) yogurt maker. Place lid on top Again, set to 100* and 36 hours. MAGIC HAPPENS WITH THIS BATCH. if everything was clean and pristine, then you will see a glorious white batch of creamy (or mildly gently clumpy) yogurt. Place in fridge to cool down and firm up. Dont pour off any liquid (there shouldnt really be any). If want extra firm product then could strain in yogurt cloth like regular yogurt recipes. I dont bother as I dont want to miss out on any of the whey. But could drain/strain and collect it. Any other issues (bad color, smell, taste) is on your environments. Sounds like contamination. ALSO, remember 36 hours is a must! the growth of l. reuteri doesnt really begin until around hour 30 or so, and it REALLY needs the full 36 hours at 100 degrees. I truly hoped this helped, and I hope it turns out well for you and that you notice the wonderful benefits from consuming probiotics. Doesnt take long to see and feel benefits!
Review: This is great for making the L. Reuteri Yogurt - This supplement is wonderful for making the L. Reuteri Yogurt. I use a coffee grinder to grind the tablets for the slurry. The coffee grinder is only used for this purpose so there is not a concern of contamination. I love the taste of the L. Reuteri Yogurt. I started eating this to help get a good nights sleep. This has worked wonderfully for me. When I forget to eat this before going to bed - I don't sleep as well. This, the Ultimate Probiotic Yogurt Maker and the Inulin have been a great addition to my lifestyle.

## Questions & Answers

**Q: Anybody know where to buy lactobacillus reuteri atcc pta 6475 higher than 200 million cut? i need like 5 or 10 billion**
A: Culture it. That is to say,  you can make a yogurt with this as your starter. I have been doing it successfully for a few months.  And using inulin in your milk substrate, your counts may likely approach 500 billion if the thinckness of this yogurt is any indication, although i've not tested the CFUs. If you search for dr william davis yogurt the 1st result should be for making l reuteri yogurt, only thing i do different is i pasteurize my milk to 165 (in microwave so no scorching) and in doing this i have not had to re-inoculate the batches every 5th batch, pull off starter at 12 hours and save in fridge for next batch.

**Q: How do I know this is going to survive the intenstial tract ?**
A: BioGaiaâs L. reuteri is the only Lactobacillus probiotic that naturally occurs in the gastrointestinal (GI) tract.  Studies have shown that L. reuteri, when supplemented in the diet, both survives and colonizes the entire GI tract, including the stomach.

**Q: Where is made?**
A: The country of origin for the BioGaia Gastrus is Belgium

**Q: What exactly is the source of the asorbic acid ingredient???**
A: The ascorbic acid in Gastrus is a synthetic L-ascorbic acid.

### ⭐⭐⭐⭐⭐ Probiotic good for SIBO/IBS/Gut health
*by J***R on November 4, 2025*

This was recommended while I’m fighting SIBO and for the benefit of gut health. So far, I’m happy with it, very easy to take, and I think slowly helping improve my gut along with oil of oregano and allicin. It’s chewable, and has a mild taste so very easy to take. Texture is fine, doesn’t bother me. Seems good quality and value for the price.
