What Dr. Eric Berg Says About L. Reuteri — And Why Your Body May Need It
If you follow natural health expert Dr. Eric Berg, you may have heard him discuss the remarkable benefits of Limosilactobacillus reuteri (formerly known as Lactobacillus reuteri), a probiotic bacterium that plays an important role in gut health, immunity, mood, and overall wellbeing.
At Exercise Therapy Systems, we offer a premium L. Reuteri Probiotic Yogurt Starter Culture so you can make highly concentrated probiotic yogurt at home using the same strains made famous by Dr. William Davis.
Who Is Dr. Eric Berg?
Dr. Eric Berg is widely known for his educational videos on nutrition, gut health, fasting, and hormone balance. He often discusses the importance of restoring beneficial gut bacteria and reducing factors that damage the microbiome, such as antibiotics, processed foods, and chronic stress.
Although he emphasizes lifestyle and dietary strategies rather than relying solely on supplements, Dr. Berg has highlighted specific probiotics—particularly L. reuteri—for their broad potential benefits.
What Dr. Berg Says About L. Reuteri
According to Dr. Berg, L. reuteri is one of the most valuable probiotic strains because it may support:
- Better digestion and gut balance
- Reduced bloating
- Improved immune function
- Healthier skin and collagen production
- Better sleep and mood
- Hormonal balance
- Increased oxytocin ("the bonding hormone")
- Stronger bones and muscles
His discussions align with published research and with the work of Dr. William Davis, who popularized homemade L. reuteri yogurt. L. reuteri is a naturally occurring bacterium found in the human digestive tract and in breast milk, but many people may have lower levels today due to antibiotics and modern dietary patterns.
Why We May Need More L. Reuteri Today
Modern life can significantly reduce beneficial gut bacteria, including L. reuteri:
- Antibiotic use
- Chlorinated water
- Processed foods
- Chronic stress
- Poor sleep
- Environmental toxins
When beneficial bacteria decline, people may experience digestive discomfort, immune issues, sleep problems, and skin changes. Dr. Berg frequently emphasizes that rebuilding the microbiome can have effects far beyond digestion.
The Oxytocin Connection
One of the most fascinating features of L. reuteri is its association with oxytocin, a hormone involved in:
- Relaxation and stress reduction
- Social bonding
- Better sleep
- Skin repair
- Appetite regulation
This may help explain why some people report improvements in mood, sleep quality, skin appearance, and even body composition after regularly consuming L. reuteri yogurt.
Why Homemade L. Reuteri Yogurt Is So Powerful
While probiotic capsules can be helpful, homemade yogurt allows the bacteria to multiply during fermentation over 24–36 hours. This creates a much higher concentration of live organisms than most supplements provide.
Benefits of making your own yogurt include:
- Very high probiotic counts
- Delicious creamy texture
- Cost-effective daily use
- Ability to customize ingredients
Clinically Studied Strains
Our L. Reuteri Probiotic Yogurt Starter Culture contains two of the best-known and most widely studied strains:
- DSM 17938
- ATCC PTA 6475
These are the same strains commonly used in Dr. William Davis’s well-known yogurt protocol.
