Starter Set L. reuteri, L. gasseri, B. coagulans Yogurt | SIBO Yogurt

Starter Set L. reuteri, L. gasseri, B. coagulans Yogurt

For a strong microbiome in SIBO

With L. reuteri, L. gasseri, B. coagulans

Each yogurt base contains:

• 4 capsules of Limosilactobacillus reuteri (5 billion CFU each)
• 1 capsule Lactobacillus gasseri (12 billion CFU each)
• 2 capsules of Bacillus coagulans (4 billion CFU each)
  

A total of 7 capsules per batch.

Our starter cultures are manufactured in a GMP-certified laboratory and, before shipping, are tested by an external accredited laboratory for identity, purity, and viable count.

Fermentation temperature

L. reuteri grows slowly, needs prebiotics such as inulin, and prefers mild temperatures. It performs best at about 37–42 °C.

L. gasseri ferments reliably under suitable conditions. It prefers a low-oxygen environment and temperatures around 37–42 °C.

B. coagulans is a heat-stable spore former. It becomes active from about 40 °C and needs an environment of roughly 41–43 °C.

An optimal fermentation temperature of 106 °F (41 °C) is a good compromise. It is warm enough to activate all three strains (especially B. coagulans, which prefers higher temperatures) and gentle enough that L. reuteri is not harmed.

Three key strains, powerful microbiome support

The starter set includes Limosilactobacillus reuteri, a clearly defined lost species, meaning a microbe that is often greatly reduced or nearly absent in modern Western gut ecosystems.

Lactobacillus gasseri occurs less frequently than in the past and is uncommon in many Western microbiomes without external intake, but it is not considered a classic lost species.

Bacillus coagulans is not a gut bacterium in the strict sense. It is a spore-forming soil organism that appears only occasionally in the gut. It is not a lost species but a rare, introduced species with distinctive stabilizing properties for the gut.

This combination therefore pairs one classic lost species with rare yet proven strains for targeted, versatile support of your microbiome.

3-strain yogurt: L. reuteri, L. gasseri, B. coagulans

This special combination brings together the lost species Limosilactobacillus reuteri with the uncommon, health-promoting species Lactobacillus gasseri and Bacillus coagulans 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.

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

What happens when you re-culture?

Finished yogurt can be used as a starter multiple times. Over several 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.

For our 3-strain yogurt this means:
L. reuteri is particularly sensitive to genetic changes and over time loses its ability to stimulate central messengers such as oxytocin.

L. gasseri is robust and ferments reliably, but with very frequent reuse activity can decline as the population adapts and becomes less diverse.

B. coagulans is resilient as a spore former, yet viable counts can also drop with repeated reuse.

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