The science, in plain English

One strain and a fibre, explained

A single bacterial species with a long history in fermented foods, paired with a fibre from chicory root. Here is what each one is.

Mechanism 01

A bacterium named after its discoverer.

How it works

Lactobacillus reuteri is a lactic acid bacterium found naturally in the human gut and in fermented foods. It is named after the German microbiologist Gerhard Reuter, who studied it in the 1960s. In 2020 it was reclassified under a new genus, so you will also see it written Limosilactobacillus reuteri.

About Roundway

What if the best ideas come from the people taking them?

We grew up with parents who cared about nutrition and good food, and we’ve spent years listening to friends and practitioners who champion clean-label products. So we build the way we were taught to eat: start with what’s real, and leave out what isn’t needed.

That’s why every Roundway pack starts with what you ask for. Conversations at our talks and stands, messages in our inbox and your reviews shape what we make next, and how we label it.

Then we gave people a first look at our 2027 range. The feedback said it all: this is how supplements should be made.

How 10 billion bacteria fit in a capsule

Step through how a culture of L. reuteri becomes the powder in each capsule.

The strain

Production starts from a characterised culture of a single bacterial species.

In each capsule

33.3mg L. reuteri powder (10 billion CFU) with 225mg chicory inulin.

Lactobacillus reuteri, answered

How much L. reuteri is in each capsule?
Each capsule provides 10 billion CFU of Lactobacillus reuteri, with 225mg of inulin from chicory root.
What is Lactobacillus reuteri?
A lactic acid bacterium found naturally in the human gut and in fermented foods such as sourdough. It is named after the microbiologist Gerhard Reuter.
Why is it also called Limosilactobacillus reuteri?
In 2020 the large Lactobacillus genus was split into 25 groups, and L. reuteri moved to the new genus Limosilactobacillus. It is the same bacterium.
What does CFU mean?
Colony-forming units: each living cell that grows into a visible colony on a lab plate counts as one.
What is inulin?
A fibre made of chains of fructose. Ours comes from chicory root.
How do I take it?
Take one capsule a day with water. Do not exceed the recommended daily dose. A pack of 60 lasts two months.
Is it vegan?
Yes. It is suitable for vegans and vegetarians, in a plant-based capsule.
Can I take it if I am pregnant, breastfeeding or on medication?
Speak to your GP or pharmacist before taking any food supplement if you are pregnant, breastfeeding, taking medication or under medical supervision.
