Bifidobacterium plantarum and Improved Gut Microbiota Composition

Research synthesisVery low evidenceModerate effect3 studies · 3 beneficial · 0 neutral · 0 harmful

Across 3 studies, all reported beneficial effects on gut microbiota composition, with effect sizes ranging from small to moderate. The strongest evidence comes from a systematic review in adults with alcoholic liver disease, showing an increase in beneficial bacteria (e.g., Lactobacillus, Bifidobacterium) and a decrease in pathogenic taxa. No dose, duration, or form data were consistently reported.

  • Studied populations: adults with alcoholic liver disease (ALD)

Caveats: Evidence base is small (only 3 studies) — conclusions should be considered preliminary. Available evidence is overwhelmingly positive — clinical literature in this area is subject to publication bias (null-result studies are less likely to be published or indexed). None of the included studies reported statistical significance, and two studies lacked clear population or sample size details, limiting generalizability.
