Faecalibacterium prausnitzii

Low Faecalibacterium prausnitzii is recognized in research as a near-biomarker for inflammatory bowel disease. Bifidobacterium cross-feeds Faecalibacterium prausnitzii by providing enzymes to break down fermentable fibers, so supplementing Bifidobacterium directly supports both organisms. Faecalibacterium prausnitzii is the gut's primary butyrate producer, and butyrate is the main energy substrate for colonocytes. Absence of Faecalibacterium prausnitzii can simultaneously cause gut and neurological symptoms, including panic attacks and brain fog. Partially hydrolyzed guar gum is a well-researched prebiotic fiber that specifically supports Faecalibacterium prausnitzii recovery.
