Why Are These Three Bacterial Strains Widely Studied?
L. reuteri BIO5454 is frequently discussed in scientific literature as a Lost Species because it is considered to be much less common in modern populations than it was historically.
Lactobacillus gasseri BIO6369 is among the most extensively studied Lactobacillus strains in microbiome research and has been widely investigated in connection with metabolism, body composition, and the gut microbiome.
Bifidobacterium longum BB536 is one of the most extensively studied Bifidobacterium strains and has been investigated in numerous scientific publications related to the gut microbiome, metabolism, digestive physiology, the immune system, and the intestinal barrier.
Together, these three bacterial strains represent some of the best-known cultures used for homemade yogurt fermentation and microbiome research.

Frequently asked questions (FAQs)
How many yogurt batches can I make from one starter?
Each starter prepares one initial batch of yogurt.
The finished yogurt can then be used as a starter for additional batches.
Dr. William Davis recommends restarting with fresh capsules after approximately 20 recultures.
While no scientific study has established a maximum number of recultures for homemade L. reuteri yogurt, food microbiology research indicates that repeated propagation of bacterial cultures can lead to genetic drift, selection of subpopulations, contamination, and changes in fermentation performance over time.
This means that one starter can produce up to 21 yogurt batches, allowing one starter set to produce up to 63 yogurt batches.

What Do I Need to Make Yogurt?
To prepare yogurt, you will need:
- The bacterial cultures included in this starter set
- Milk
- A fermentation device capable of maintaining the recommended temperature
- (Suitable nutrients for the bacteria, e.g. inulin)
For best results, we also recommend using a thermometer to verify the actual fermentation temperature.
Many fermentation devices do not maintain exactly the temperature shown on their display.
A simple kitchen thermometer can help confirm that the desired fermentation temperature is being reached throughout the fermentation process.
Successful fermentation depends on several factors, including the milk used, fermentation temperature, and the availability of suitable nutrients for the bacteria.
The included guide contains detailed preparation instructions and proven recipes.
Why is fermentation temperature so important?
Maintaining the correct fermentation temperature is one of the most important factors for successful yogurt preparation.
Temperatures that are too low may slow bacterial growth, while temperatures that are too high may reduce bacterial viability.
Many yogurt makers do not maintain exactly the temperature shown on their display.
We therefore recommend checking the actual temperature with a simple kitchen thermometer.
Detailed temperature recommendations for each starter set are included in the guide provided with every order.

Which yogurt maker do you recommend?
Any yogurt maker that can maintain a stable fermentation temperature for the required fermentation time can be used.
For best results, we recommend verifying the actual temperature with a thermometer, as many devices operate at temperatures that differ from their displayed settings.
Many customers successfully use Luvele yogurt makers because they provide stable temperatures using a water bath.
However, many other devices also work well when the correct temperature is maintained.
Which milk should I use?
Many of our customers successfully prepare yogurt using UHT milk, goat's milk, sheep's milk, or coconut milk.
If you use fresh milk, we recommend boiling it first to reduce naturally occurring bacteria that may compete with the starter culture.
Allow the milk to cool to 35 °C (95 °F) or below before adding the starter cultures.
The higher the fat content of the milk, the creamier the yogurt will generally be.
Lower-fat milk can also be used but typically produces a thinner consistency.
Milk with 3.5% or 3.8% fat is generally sufficient to produce a yogurt with a creamy consistency.

Do I have to use inulin? Are there any alternatives?
No.
Many customers successfully prepare yogurt using only milk and the starter culture without adding inulin.
If you would like to add a prebiotic, we recommend inulin, as this is the method recommended by Dr. William Davis and has consistently produced reliable results.
If you cannot tolerate inulin, you can simply prepare the yogurt without it, provided that your milk contains lactose.
The bacteria can use lactose, the naturally occurring milk sugar, as an energy source during fermentation.
We do not have sufficient experience with fermentation using lactose-free milk without adding inulin or another suitable carbohydrate source.
In this situation, fermentation may be less reliable because the bacteria require a fermentable carbohydrate to grow and multiply.

Why doesn't the first batch always look like yogurt?
It is completely normal if the first fermentation does not produce a perfect yogurt.
Some first batches separate into whey and a firmer curd-like portion because the bacteria first need to adapt to their new environment and multiply before they can consistently produce a stable yogurt texture.
Do not discard the first batch.
Simply pour off the whey if desired and use about two tablespoons of the firm portion as the starter for your next batch.
From the second fermentation onward, the culture is usually much more active and produces a much creamier, more stable yogurt.
This behaviour is commonly reported by home fermentation communities and is consistent with our own customer experience.

How should I store the starter cultures, and how sustainable is the packaging?
For best results, store the starter cultures in a cool, dry place.
For optimal long-term storage, refrigeration is recommended.
Always reseal the pouch after removing capsules to help protect the bacterial cultures from moisture during storage and handling.
Our starter cultures are supplied in a resealable pouch made from 100% recycled plastic.
Using 100% recycled plastic packaging helps reduce the demand for virgin plastic while providing durable, moisture-resistant packaging that protects the bacterial cultures throughout storage and transport.
Where are your starter cultures manufactured and how is quality assurance maintained?
Our starter cultures are produced in a GMP-certified manufacturing facility specializing in bacterial cultures under strict quality assurance procedures.
Each batch is monitored throughout production and laboratory tested to verify identity, purity, viable cell count, and quality before release.
Stability testing is performed to verify that the declared CFU count is maintained throughout the product's shelf life when stored as recommended.
This ensures that every starter culture meets the declared quality specifications before it reaches our customers.
