Three key strains, two lost species, one strong microbiome

With L. reuteri and B. infantis, the set includes two clearly identified lost species, microbes that have largely disappeared from modern gut ecosystems. L. rhamnosus is not a classic lost species, yet it shows similar health-promoting properties and has become increasingly rare in Western microbiomes without external supplementation.

3-strain yogurt: L. reuteri, L. rhamnosus & B. infantis

This special combination brings together two of the most important lost species, Limosilactobacillus reuteri and Bifidobacterium infantis, with the most researched all-rounder Lactobacillus rhamnosus to create a powerful yogurt that goes far beyond classic probiotics.

All three strains support the microbiome in different ways and act via the gut–brain axis throughout the body, including by demonstrably sending chemical messengers from the gut to the brain. L. reuteri, for example, stimulates the release of oxytocin, the bonding and healing hormone, which has far-reaching effects on mood, sleep, muscle development, and immune regulation.

Their targeted use can trigger processes that many users describe as life changing.

With the starter set you can prepare your own 3-strain yogurt, fresh, high dose, and without additives.

For one yogurt batch, the following cultures are used in this combination:

At least 5 to 20 billion CFU are required.
Result: 4 capsules of 5 billion CFU = 20 billion CFU

Also high dose and easy to ferment.
Result: 2 capsules of 10 billion CFU = 20 billion CFU

Very sensitive.
Result: 2 capsules of 1 billion CFU = 2 billion CFU

What happens when you re-culture?

Finished yogurt can be used as a starter several times. Over multiple generations, however, the culture can change. Spontaneous mutations, contamination, or the selection of faster growing subtypes can reduce effectiveness. Dr. William Davis, who developed the method, recommends starting fresh with new capsules after 20 batches at the latest. This preserves the physiological activity of the bacteria.

Why 20 generations?

Food microbiology studies show that lactic acid bacteria can undergo genetic changes after about 10 to 30 passages. These changes arise through spontaneous mutations, natural selection, or contamination and can lead to a decline in certain health-promoting properties.

For our 3-strain yogurt this means:

• L. reuteri is particularly sensitive to genetic change and over time loses its ability to stimulate central messengers such as oxytocin. Regular rebooting is crucial to maintain its physiological activity.

• L. rhamnosus is robust, yet repeated fermentation can still reduce diversity and select dominant substrains that no longer produce all intended effects.

• B. infantis is difficult to cultivate in any case. With repeated reuse, its numbers drop quickly because it requires very specific nutrients and conditions.
  

We therefore recommend a fresh start with new capsules after 20 batches at the latest to ensure that the bacteria can fully develop their intended effects.

Our starter set is suitable for anyone who wants to use yogurt specifically to support the gut, the immune system, and mental well-being. It is for everyone who wants to bring L. reuteri, L. rhamnosus, and B. infantis back into daily life as lost or displaced species, with clear effects and uncompromising quality.
