UPDATE: We have tested our own reciepe and updated the article with it here
Maintaining good health is essential for a strong body and mind, especially in today’s world, where wellness plays a crucial role in our daily lives. At S.A. Self Defense, we believe that good nutrition is a form of self-defense, keeping you resilient against illnesses and enhancing your overall well-being.
One of the best ways to support your health is by incorporating probiotic-rich foods into your diet. Dr. William Davis’ Probiotic Yogurt is a powerhouse of gut-friendly bacteria, specifically designed to enhance digestion, boost immunity, and even improve mental clarity. Let’s explore the benefits of this yogurt and how you can make it at home!
NOTE: There is a lot to this healthy formula. When choosing Limosilactobacillus reuteri (formerly known as Lactobacillus reuteri), it’s crucial to select the right strain. Not all L. reuteri bacteria have the same effects, and just buying any L. reuteri supplement may not work for your specific health goals.
Each strain has unique properties that affect different aspects of gut health, immunity, skin, metabolism, and hormone balance.
Here is a link to our guide to the strains to help you know and search for the right ones
Why Dr. Davis’ Probiotic Yogurt?
Unlike store-bought yogurt, which often contains minimal probiotic strains, Dr. Davis’ yogurt is specially formulated to provide high levels of beneficial bacteria, particularly Lactobacillus reuteri (L. reuteri). This probiotic strain has been shown to:
✅ Support gut health – Helps balance the gut microbiome and improve digestion.
✅ Enhance immune function – Strengthens the body’s defenses against infections.
✅ Improve skin and collagen production – Promotes youthful, healthy skin.
✅ Boost mood and reduce stress – Supports neurotransmitter function, which can help with anxiety and depression.
✅ Regulate weight and metabolism – Aids in appetite control and fat burning.
The key to unlocking these benefits is fermentation—a process that allows beneficial bacteria to multiply, making this yogurt a nutritional powerhouse!
Why Dr. Davis’ 36-Hour Fermentation Method Works
Dr. Davis’ yogurt method stands out because of its extended 36-hour fermentation period. Unlike commercial yogurts, which are typically fermented for 4 to 8 hours, this longer cure time allows for a much higher concentration of beneficial probiotics. Here’s why it works:
✅ Maximizes Probiotic Growth – The extended fermentation time gives L. reuteri bacteria more time to multiply, significantly increasing their numbers compared to standard yogurt.
✅ Boosts Nutrient Bioavailability – The longer process helps break down lactose and proteins, making nutrients more accessible and digestible.
✅ Enhances Health Benefits – Higher probiotic levels mean greater impact on gut health, digestion, immunity, skin, and even hormone regulation.
✅ Creates a Richer, Creamier Texture – The extended fermentation results in a thicker, creamier yogurt with a smooth, mild taste.
This method ensures that the yogurt is not just a dairy product but a highly potent probiotic supplement, giving your body maximum benefits with every spoonful.
Benefits of Inulin Prebiotic Fiber (Chicory Root Powder)
Adding inulin prebiotic fiber (such as chicory root powder) to your diet can further enhance gut health and digestion. Here are some key benefits:
✅ Promotes Gut Health – Acts as food for beneficial gut bacteria, helping probiotics thrive.
✅ Improves Digestion – Supports regular bowel movements and helps prevent constipation.
✅ Supports Blood Sugar Control – May help regulate blood sugar levels by slowing digestion.
✅ Aids in Weight Management – Helps promote satiety, reducing overeating and cravings.
✅ Boosts Calcium Absorption – Enhances the body’s ability to absorb calcium for stronger bones.
✅ Supports Heart Health – May help lower cholesterol levels and improve overall heart function.
Inulin is a water-soluble fiber that blends easily into yogurt, smoothies, and other foods, making it an easy and effective addition to a healthy diet.

The Ultimate Yogurt Maker
When choosing a yogurt maker you want the best otherwise you might make that bad batch. We’ll here is the best: The Ultimate Yogurt Maker. This maker will keep track of time for you, let you adjust the temature and it is always on point with the temp. evenly, which is important when making yogurt.
Not only that it comes with a “unlimited lifetime warrranty” (see what they did there. lol)
With our first batch of yougurt this maker made it perfect and has done ever since oh and will do for a lifetime.

You can purchase the ultimate yogurt maker from there website or amazon with the links below:
The ultimate yougurt maker website: $69.00
The ultimate yogurt maker amazon: $69.00
Many commercial probiotics do not specify their strain, which means you may not get the benefits you expect. When purchasing L. reuteri, always check the strain number to ensure it matches your health goals.
How to make the yougurt: Source
You will need:
–Glass or ceramic bowl or other vessel large enough to hold at least one quart of liquid
–2 tablespoons of prebiotic fiber such as inulin
–Starter: Either 10 tablets of BioGaia Gastrus or 1 tablet of 20bil MyReuteri
–1 quart of half-and-half or other liquid (to make with coconut milk, several additional steps and ingredients are required)
–Some method of maintaining at 100 degrees F. We are using this yougurt maker.
Yields: Around 8 one-half-cup servings
Make sure your bowl or other vessel is clean after washing with hot soap and water:

Add 2 level tablespoons of prebiotic fiber:

Add 10 crushed tablets of Gastrus (that provide 200 million CFUs of L. reuteri, a relatively small number). Crush the tablets with a mortar and pestle or by putting into a plastic bag and crushing with a rolling pin or heavy bottle/glass until reduced to a coarse powder. (The tablets are flavored with mint and mandarin, but the taste does not show in the final product, nor in subsequent batches.) Once you have made your first batch, make subsequent batches with two tablespoons of the prior batch, rather than crushed tablets; it can be any mixture of whey or solid curds, as both contain L. reuteri.

Mix either crushed tablets or 2 tablespoons prior yogurt with prebiotic fiber:

Add a little, e.g., 2 tablespoons, of your choice of dairy; I used organic half-and-half, as this yields the best texture (and, of course, we NEVER limit fat in the Wheat Belly lifestyle). Make a slurry by stirring; this prevents clumping of the prebiotic fiber. (Whole milk—NEVER low- or non-fat—yields a thinner end result, while cream yields something close to butter, too thick for my taste.)

Stir in remainder of half-and-half or other liquid:

Cover lightly with plastic wrap or other means. Ferment by maintaining at 100 degrees F for 36 hours. Prolonged fermentation—far longer than the 6 or so hours of commercial yogurts that explain why the bacterial counts are so low–in the presence of prebiotic fibers yields far higher bacterial counts in the tens to hundreds of billions per serving.
I used a basin-type sous vide device, but you can use a stick sous vide, yogurt maker with adjustable temperature control, or Instant Pot. (Just be careful with the Instant Pot or yogurt makers without adjustable temperature, as they are set to be compatible with conventional yogurt microorganisms and are often too hot and kill L. reuteri; if your device heats to 110 degrees F or higher, it will likely kill L. reuteri and you should find an alternative means of heating. If in doubt, turn on your device and measure the temperature reached with a thermometer first before you ruin a batch.) Keep your materials out of the way of fans, heating/cooling vents, or other sources of air contamination.

The end-result for me is rich, thick, and delicious, better tasting—and with far higher probiotic bacterial counts—than anything you can buy in a store. Once refrigerated, the “yogurt” is so thick that it can stand upright on a plate:

Serve with fresh or frozen berries, grainless granola, squirt of liquid stevia, or your choice of fruit or natural sweetener.

S.A. Self Defense Recepie of Dr. Davis’ Probiotic Yogurt: A Powerful Boost for Your Health
We made the yogurt as above. After the batch is made we make a protein top with berries and strawberries or bananas and cinnamon as follows:
In a blender put the following:
- 8 scoops of protein powder
- 2 cups of your favorite berries frozen or 1 banana
- 3 cups water
And blend until everything is mixed and blended. Once it’s blended pour the mix on top of the yogurt in the yogurt cups you are using. Cap the yogurt and store in the fridge.
This brings the yogurt protein up to around 29 grams of protein if your using half and half and gives it flavor.
