Faecalibacterium prausnitzii is a butyrate-producing commensal bacterium that is among the most abundant in a healthy human gut and has attracted significant research interest as a potential next-generation probiotic. Multiple reviews and observational studies have examined F. prausnitzii abundance in relation to inflammatory bowel conditions such as Crohn's disease, and animal model work has examined intestinal inflammation and gut barrier function, including in relation to a secreted protein. In vitro studies have characterized its butyrate production, including in the context of cross-feeding with bifidobacteria. Human RCT data on this organism as a direct supplement are limited, and it remains challenging to culture. These are research topics, not findings; the papers do not establish that this strain treats or prevents any condition.
Where it's been studied Tags come from a conservative keyword scan of each paper's title, abstract, and summary. A tag is research coverage, not measured effect. How we classify this →
