L Reuteri

Additional Information

L Reuteri

Lactobacillus reuteri (L. reuteri) is a probiotic strain, researched by Dr. Davis, that has drawn growing interest for its effects on gut health, skin, hormones, mood, and even immune balance. When cultured into a thick, rich yogurt, L. reuteri becomes a highly concentrated functional food that can be used as part of a natural wellness routine. L. reuteri yogurt is made by fermenting milk with the probiotic strain Lactobacillus reuteri. Unlike typical yogurt cultures, L. reuteri requires a longer fermentation time and warmer temperature, resulting in:

thicker, creamier texture
extremely high probiotic count (often billions CFU per spoonful)
a tangy, mild flavor
the ability to use dairy or non-dairy milk with a thickener

Because the bacteria multiply so densely, this yogurt acts more like a therapeutic food than a standard snack. L. reuteri is naturally found in the human digestive tract, but many modern adults no longer carry it due to antibiotics, stress, and diet.

Research suggests that consuming L. reuteri yogurt may help:

increase beneficial bacteria in the gut
reduce inflammatory gut microbes
support smoother digestion
promote regular bowel movements
encourage a healthier intestinal lining

Many people report feeling lighter, less bloated, and more balanced after enjoying a half cup a day consistently.

L. reuteri plays a significant role in immune regulation. It supports:

healthy inflammation balance
increased production of regulatory T-cells
improved immune tolerance
reduction of occasional digestive or skin flare-ups

Because much of the immune system resides in the gut, feeding the microbiome with supportive bacteria can positively influence whole-body wellness.

A growing body of research links L. reuteri to clearer, more radiant skin.
This effect is primarily due to its influence on:

inflammation balance
gut-skin axis signaling
microbiome diversity

In studies, those consuming L. reuteri saw improvements in dryness, tone, and overall complexion appearance.

The gut communicates constantly with the brain through the vagus nerve and microbial metabolites. Many describe a subtle but noticeable shift toward emotional steadiness after several weeks of daily intake. L. reuteri may support:

calmer mood
emotional resilience
reduced occasional stress responses
improved feelings of social connection (via oxytocin pathways)

Some research suggests that L. reuteri can influence hormone pathways, including:

improved oxytocin signaling
potential support for reproductive health
healthier inflammatory balance that indirectly supports hormones

L. reuteri is also present in the natural oral microbiome. Studies indicate it may help:

reduce harmful bacteria in the mouth
support gum health
maintain fresher breath
balance oral flora

Some dentists are now recommending specific L. reuteri probiotic lozenges alongside yogurt.

While results vary, improvements in sleep quality are one of the most commonly reported benefits.

Because L. reuteri positively influences oxytocin and stress-regulation pathways, many people find this yogurt helps:

ease nighttime tension
support deeper rest
promote a more balanced circadian rhythm

Most people enjoy:

4 ounces per day
mixed into smoothies
as a topping for fruit
blended with honey or cinnamon
taken alone

Making L. reuteri Yogurt (High-Potency)

Makes: 1 quart
Fermentation: 36 hours

Programable Yogurt Maker https://amzn.to/48188bG

Ingredients

Dairy Version

1 quart (4 cups) organic whole milk (cow or goat, ultra-pasteurized) or A2 milk
1 tablespoon inulin (prebiotic fiber that feeds the bacteria) https://amzn.to/3WWdG1V
1 probiotic capsules containing Lactobacillus reuteri https://amzn.to/4p9o8PC

Non-Dairy Version (Coconut)

2 cans (28 oz total) full-fat coconut milk
1 tablespoon inulin https://amzn.to/3WWdG1V
1 L. reuteri probiotic capsules https://amzn.to/4p9o8PC
1 tablespoon gelatin or agar agar (for thickening)

Equipment

Yogurt maker set to 100–105°F, or https://amzn.to/48188bG
glass jars or containers with lids
Non-metal spoon for stirring https://amzn.to/3XxJNVO

Step-By-Step Directions

1. Heat the Milk (Dairy Version Only)

Gently warm the milk to 180°F and hold for 5 minutes.
This improves thickness. Dr. Davis does not do this step. I have done it both ways.
Cool to 100–105°F before adding probiotics.

(Skip this step for coconut milk.)

2. Mix the Base

In a clean bowl or jar:

Add 1 tablespoon inulin and contents of the 1 capsule
Stir in 2 tablespoons milk until not lumpy.
Then add in remaining milk

3. Ferment for 36 Hours

Place the jar in your yogurt maker:

Temperature: 100–108°F ONLY
Time: 36 hours
Do NOT exceed 108°F, or the L. reuteri will die.

You should see slight thickening after about 18 hours.

4. Refrigerate

After fermentation:

Chill the yogurt for at least 4 hours.
It will thicken noticeably as it cools.

5. Save a Starter for Next Time

Reserve ¼ cup of finished yogurt
Use it as the starter for your next batch (up to 5–7 generations). This saves money and maintains a strong culture.

How to Use L. Reuteri Yogurt

Most people take:

½ cup daily
Mix into smoothies, fruit bowls, chia pudding, or eat plain or with fruit on top.
