L. Reuteri — The Bacteria You’re Missing and the Superfood Yogurt I Love!
The Journey — Finding answers
Before refrigeration in 1927, everybody fermented their food. It was what people did to keep their foods safe and preserved. They would ferment their milk and their vegetables. They also made drinks teeming with good yeasts and bacteria - water could be risky since it wasn't always clean. They would even bury their meat in the ground and let it ferment. They fermented everything! It was the norm, but when they developed the refrigerator with freon, they marketed it by saying fresh food was better than fermentation, and part of their marketing was to demonize fermented foods. I've lived long enough to see many foods be demonized, be it eggs, dairy, oil, etc. Then years later they say they're healthy and foods we need. I honestly don't know how people ever know what to eat or who to believe! I've realized now it's not the food, it's what we've done to the food and to our microbes. Then we have to consider our farming practices and marketing tactics to increase sales and distribution. You almost have to be a detective to know what to eat.
In less than one hundred years, the fermented foods we used to eat, that had living microbes, are now an occasional food in our diets. The consequence of this is less diversity of microbes in our guts; and then with the overuse of antibiotics and drugs, we've damaged ourselves to the point that many of the microbes we need to be healthy no longer abide within us.
It's sad that wellness doesn't seem to be the norm anymore but rather the exception. So it is my heart's desire to help you find that wellness and keep it for the rest of your life. But you'll need some help as I did many years ago. You'll need those microbes that abide within and all around us to flourish and to teach you. They're the secret to everything going on inside of you. They were placed there to help you create enormous wellness and they outnumber us all by the trillions. This is a time in history of an abundance of information. But not only that, it's also a time to know how to accomplish the task of wellness.
IBS, SIBO, and SIFO
With more and more people struggling with IBS (irritable bowel syndrome), SIBO (small intestinal bacterial overgrowth), and SIFO (small intestinal fungal overgrowth), I knew we needed answers to help this unique problem. Most of this is occurring in parts of the body where the wrong bacteria have gotten into the wrong place. Fermented foods can be problematic with these ailments, and yet eliminating fermented foods is not the answer. At the root of the problem is often a dysbiosis in the gut and bacteria in the wrong place, and it can be very frustrating. I've been searching for answers to help those in need and I believe I have a good place to begin the healing process for those who are hurting. Wouldn't you know it comes in the form of a fermented yogurt that uses a specific strain of bacteria that most are missing. Microbes always seem to come to me when needed most, and I'm very thankful for the wellness they create.
Dr. William Davis, MD — Super Gut Book
Lactobacillus reuteri (L. reuteri) bacteria species is a superstar in the world of intestinal microbes, and you might just think you can take a supplement with L. reuteri and accomplish the task but that's not necessarily true. Supplementation in pill form isn't always optimum and there are specific strains of L. reuteri for humans and animals. Someone who has done a ton of research on this species and developed a way to make a yogurt high in L. reuteri, which the body readily absorbs, is Dr. William Davis, MD. He is the author of the fantastic book "Super Gut". Check out my podcast with him below.
The yogurt manufacturers told him that making yogurt with L reuteri couldn't be done. Since L. reuteri is really a cultured dairy and made with completely different strains of bacteria than conventional yogurt, it also required different temperatures and longer fermentation times. Nobody was really making this because they didn't think it could be done. However, he had made dozens of successful batches, had them tested in a lab, and they all had high counts of L. reuteri. The secret was keeping the temperature about 100°F, letting it ferment for 36 hours, and giving it a prebiotic. The long, slow fermentation increases the bacterial strains exponentially over the 36 hours (see graph below) and creates a thick delicious yogurt.
Dr. Davis states: "Modern life has eradicated this species from 96 percent of people in the modern world. Today only 4 percent—fewer than 1 in twenty people—continue to enjoy this marvelous species."
Let me explain to you the health benefits and just how to make this special yogurt which can help you in many ways, especially if you're struggling with things such as SIBO, leaky gut, low energy, loss of muscle and bone, and metabolic syndrome. Fermented foods work significantly better than probiotic supplements since the body knows what to do with food as it speeds to the parts of the body that is needed. Probiotic pills are often killed in stomach acid and never give you the strains or amounts you need.
Lactobacillus Reuteri Health Benefits
Oxytocin the Love Hormone and L. Reuteri
One of the most interesting benefits of L. reuteri is its ability to release the hormone oxytocin from the human brain. [1,7] If you had a baby or have been in love you know how wonderful oxytocin can be. As the hormone releases, we feel more love and connectedness and we all need more love and compassion for one another. These have been stressful times in the last few years and fear tends to separate and cause division. With the loss of L. reuteri in most of the population, we must all have lower levels of oxytocin. Our body is a virtual pharmaceutical factory and can create more of the things we need, if it is given what it needs. Who would have thought a bacteria could do this? It certainly is amazing all our microbes can do, which is why I love them so very much!
SIBO, IBS and L. Reuteri
Those with SIBO have the wrong types of bacteria living in their small intestines. Those harmful bacteria do not belong there and create quite a ruckus. L. reuteri is very unique compared to most bacteria that live in the six-foot-long colon. L. reuteri prefers to colonize the upper gastrointestinal tract (in the stomach, duodenum, jejunum, and ileum) which is 22 feet long. While it takes residence in the upper GI tract it produces natural antibiotics called bacteriocins that are very effective against undesirable bacteria species that live in the small intestine that can cause SIBO. Loss of this special species is likely the reason more and more people are experiencing SIBO. Restoring this species is becoming part of the solution to SIBO.[2,3] I highly recommend you check out Dr. Davis' book Super Gut if you're struggling with SIBO. He has ways to help you test your breath with a small device and smartphone to see if your bacteria are producing hydrogen gas. This can be a side effect that can occur when the wrong bacteria are abiding in the upper gastrointestinal tract. He's helped dozens of people find success in changing this challenging ailment.
Candida and L. Reuteri
L. reuteri exhibited antifungal properties against five of the six most common oral Candida species. It completely eliminated these species and is now being studied for the treatment of SIFO (small intestinal fungal overgrowth). SIFO is characterized by the presence of an excessive number of fungal organisms in the small intestine associated with gastrointestinal (GI) symptoms. 
Candida can be quite a challenge, but having large amounts of good bacteria keeps candida in check. We need balance not complete extinction and having the proper flora makes this a natural process.
Improves Skin, Muscle Growth, Bone Density, Slenderness, and Increased Insulin Sensitivity
Researchers at MIT were doing studies on cancer and observed the following effects on elderly animals given L. reuteri compared to those who did not receive L. reuteri.
- Improved and created rapid hair growth
- Thicker skin, with a substantial increase in dermal collagen
- Acceleration of skin healing
- Created slenderness and appetite control
- Reduced levels of the stress hormone cortisol
L. Reuteri reduced age-related bone loss in women 75 to 80 years of age with low bone density. [5,6]
Other studies have found that L reuteri restores youthful muscles, and improves insulin sensitivity.[7,8,9,10]
Colic and L. Reuteri
According to clinical research, L. reuteri can help infants with colic. In this study, eighty-three infants completed the trial taking L. reuteri (Probiotic drops, BioGaia AB) or the placebo for one week. L. reuteri improved infantile colic and symptoms such as crying time in breast-fed infants by 95%.
H. Pylori and L. Reuteri
Some studies have shown that L. reuteri has the potential to help eradicate H. pylori from the intestine when added to standard H. pylori therapy. L. reuteri works by competing with H. pylori and inhibiting its binding to glycolipid receptors. The competition reduces the bacterial load of H. pylori and restores balance. 
Deep Restful Sleep
L. reuteri can create deep restful sleep especially if you've been struggling with sleeping. I and my family have personally experienced deep sleep from this yogurt.
Check out this article and podcast to learn more about this profound effect on sleep when consuming this yogurt.
How to Make L. Reuteri Superfood Yogurt
So are you ready to learn how to help your body restore L. reuteri? Dr. Davis has numerous videos and resources on how to make it with specific probiotic strains of L. reuteri. You can find this in his book and website. We took it a step further and made an L. reuteri superfood starter culture that you can use right away so you can make lots of L. reuteri yogurt. There are a few things you need to know and you'll need an appliance that also keeps it at the right temperature and time. But no worries, I have figured most of this out for you and will leave suggestions of things you can use. I have two recipes - one for dairy and one for coconut milk yogurt. The dairy one is easy to make but we have also made a non-dairy coconut version that will work too with a few more steps. Both of these yogurts have been made and tested in labs and the bacteria count is as follows.
Frequently Asked Questions
We've had a huge response to this new starter culture, thank you so much! With any new product, there are naturally a lot of questions. So I put together an FAQs post all about this L. Reuteri Superfood Yogurt Starter.
Study Results of LR Superfood Starter
The first was made with whole milk 🥛directly from an LR Superfood sachet according to CEC (Cutting Edge Cultures) instructions for 36 hours.
The results were a total CFU (Colony Forming Unit) count per gram of 645 million. A half-cup serving is 118g, so that is 76B per serving. The make-up of the CFUs was:
The 2nd test was made with coconut milk 🥥 per CEC (Cutting Edge Cultures) instructions for 36 hours except, using LR Superfood sachet as starter and guar gum to thicken. The results were a total CFU (Colony Forming Unit) count per gram of 569 Million, so that is 67B per serving. The make-up of the CFUs was:
The Right Equipment Is Important!
To keep your L. reuteri or L. gasseri at the best temperature, you'll need an appliance with a temperature adjustment of 100°F and a timer that can be set to 36 hours. This can be a yogurt maker, Instant Pot, or sous vide device. You'll need to make sure your device has those features. Here are some appliances that should work well for you.
Luvele Yogurt Maker
This is probably my favorite of the yogurt makers that I have tried. It is a 2.1 QT (2L) Glass Container and is made by Luvele, which is a terrific company that is passionate about what they do. Highly recommended.
Luvele 4 Jar Yogurt Maker
This is another great updated yogurt maker from Luvele. You get 4 jars which are each 13.5 ounces. It keeps the temp between 78 and 122 degrees F and has a 36-hour digital. It's great for making multiple kinds of yogurt.
We've made dozens of jars of yogurt with this device. You can make larger batches so it's very convenient. It's actually a well-known cooking method used by many chefs.
You'll need a sous vide stick and a container to place the yogurt in a water bath. It allows you to make several jars at one time and controls the temperature perfectly.
Here is a link for the container I use but you can use your own container if you'd like:
Not all instapots have a manual temperature setting that can be set to 100°F.
L. reuteri and L. gasseri bacteria love human body temperature. Regular yogurt makers/instapots are usually automatically set to higher temperatures of 110°F or more, which is too hot for L. reuteri or L. gasseri to survive.
Test your device with a cup of water and a thermometer before making your first batch. I hesitate to recommend certain brands because it isn't always standard for all the pots, so please just make sure yours can maintain 100°F.
