Bifidobacterium plantarum and Improved Gut Microbiome Composition

Research synthesisLow evidenceModerate effect3 studies · 3 beneficial · 0 neutral · 0 harmful

Across 3 studies, all reported beneficial effects on gut microbiome composition, with effect sizes predominantly moderate (one large). Evidence comes from one randomized controlled trial in 120 GERD patients and an animal model study; no dose or duration data were available.

  • Studied populations: GERD patients and animal models

Caveats: Evidence base is small (only 3 studies) — conclusions should be considered preliminary. None of the included studies reached statistical significance — effect may be smaller than the predominant direction suggests. All three studies reported beneficial effects, but 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).
