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.
A bacterium named after its discoverer.
How it worksLactobacillus 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.
The everyday contextLactobacillus reuteri, providing 10 billion CFU.
How the bacteria are counted.
How it worksCFU stands for colony-forming units: a sample is spread on a lab plate, and each living cell that grows into a visible colony counts as one. It is the standard way to count lactic acid bacteria in a food supplement.
The everyday context10 billion CFU of L. reuteri.
A fibre from a coffee-substitute root.
How it worksInulin is a fibre made of chains of fructose, and chicory root (Cichorium intybus) is one of its richest sources. It passes through the small intestine without being digested.
The everyday context225mg inulin from chicory root.
