If you’ve ever wondered whether taking care of your gut could change your life, you’ll want to watch the replay of week’s livestream, “LIVE with Dr. William Davis: How L. Reuteri Can Transform Your Gut Health!“
I had the absolute pleasure of sitting down with Dr. William Davis, MD—yes, that Dr. Davis! He’s the #1 New York Times Bestselling author of the Wheat Belly series, Super Gut, and the upcoming Super Body. And let me tell you, he is just as kind and knowledgeable as you’d hope.

Power of Fermented Foods
We focused on his book Super Gut and dug into the power of fermented foods—especially L. Reuteri cultured dairy. Dr. William Davis explained why this beneficial bacteria is such a game-changer for gut health, and I was right there with him, nodding along, because if you’ve been with me for a while, you know how much I believe in the healing power of traditional, home-cultured foods.
One of the most exciting parts of our conversation was learning about his new product called MyReuteri, which makes creating that special 36-hour cultured dairy easier than ever. We also talked about Gut to Glow, his innovative blend designed to support radiant skin and overall well-being—starting from the inside out. Isn’t that amazing?
- Get MyReuteri – Dr. Davis recommends using this new formulation for making the perfect probiotic-rich cultured dairy, which many devotees refer to as super yogurt.
What Is L. Reuteri Cultured Dairy?
One of the key topics we explored was the magic of L. Reuteri—a special strain of bacteria with remarkable benefits that could help with digestion, immunity, and even emotional well-being. Dr. Davis explained how to make a gentle, slow-fermented 36-hour cultured dairy at home that becomes a living powerhouse of good microbes. It’s not just yogurt—it’s a true healing food!
Small intestinal bacterial overgrowth (SIBO)
Dr. William Davis and I chatted about how adding just a few other specific strains of bacteria (which he shares in Super Gut and on his website) to your cultured dairy can help people who struggle with Small intestinal bacterial overgrowth (SIBO)—something that so many folks deal with, often without even knowing it. (SIBO is a medical condition where the small intestine has an excessive amount of bacteria that can lead to bloating, abdominal pain, and other symptoms.)
It was comforting to hear how much science confirms what traditional wisdom has always taught us: health starts in the gut.
Gut-Brain and Gut-Heart Connection
During our chat, I couldn’t help but share something personal with Dr. William Davis—how my sweet mom always talked about the importance of “digestion.” She didn’t call it the gut microbiome back then, of course, but she knew how vital it was to feel good, sleep well, and live a long life just shy of her 99th birthday! Dr. Davis lit up when I shared that, and it led us right into a beautiful discussion about the gut-brain and gut-heart connection.
He explained how a healthy gut doesn’t just mean better digestion—it can improve your mood, immune system, and cardiovascular health. It’s all connected. And if you’ve ever felt like food could be medicine, Dr. Davis confirms that belief with his clinical expertise and compassion.
Get Practical Tips You Can Use Today
If you missed the livestream, I highly recommend watching it. It felt less like a medical lecture and more like a warm conversation at the kitchen table between two friends—filled with hope, science, and practical tips you can use right away.
I came away inspired to keep fermenting, keep learning, and keep encouraging you on your traditional foods journey. And, as a matter of fact, right after the livestream I started a new batch of L. Reuteri cultured dairy using Dr. Davis’ MyReuteri capsules. I’ll be sure to report back to you how it turned out!

Note: This is not a sponsored post. I love making and enjoying homemade L. Reuteri super cultured dairy.
Ingredients to Make L. Reuteri Cultured Dairy
- 1 quart (4 cups) of half-and-half, whole milk, ultra-pasteurized
- 1 capsule of Dr. Davis’s MyReuteri (or a verified L. reuteri probiotic)
- 2 tablespoons of inulin powder (prebiotic fiber to nourish the bacteria)
Note: Start with 1 tablespoon of inulin if you have a sensitive stomach
Tools You’ll Need
- Glass or ceramic mixing bowl
- Whisk or spoon
- Yogurt maker, Instant Pot, or sous vide with a 100°F (38°C) setting
- Small glass jars or a large jar for fermenting
How to Make L. Reuteri Cultured Dairy
- In a bowl, mix a small amount of room temperature half-and-half or whole milk with the probiotic and inulin to dissolve. Whisk together gently.
- Add the rest of the half-and-half or whole milk and whisk to combine.
- Pour the mixture into small jars or one large jar and place the jar(s) in your yogurt maker, Instant Pot or sous vide.
- Set to ferment at 100°F (38°C) for 36 hours–do not disturb during this time.
- After culturing, refrigerate for several hours before enjoying.
- Save a few spoonfuls or some of the whey to use as your starter for your next batch!
Recipe Tips
Your first batch of L. Reuteri cultured dairy may appear curdled. That’s OK. Just drain off the whey and enjoy the curds. You can use the whey to start your next batch or freeze it in an ice cube tray for later use. Your subsequent batches of this cultured dairy should be smooth and creamy and look just like thick yogurt.
Other helpful tips include:
- Use high-quality dairy for best results.
- This cultured dairy is tangy and thicker than yogurt—a little goes a long way!
- Add a bit of vanilla or cinnamon after culturing if you prefer a touch of flavor.
- If you like your cultured dairy sweeter, add a bit of stevia, maple syrup, or raw honey.
Storing L. Reuteri Cultured Dairy
L. Reuteri cultured dairy should be stored in the refrigerator and consumed within 10 days of making it.
You can also freeze the extra L. Reuteri cultured dairy you’re planning to use as the starter for your next batch.
How to Use L. Reuteri Cultured Dairy
Dr. William Davis generally recommends eating 1/2 cup of L. Reuteri cultured dairy each day for 4 weeks or each day for 8 weeks if trying to recover from severe intestinal discomfort such as SIBO. After that, it’s sufficient to eat a 1/2 cup of this cultured dairy 2-3 times per week.
