Bifidobacterium plantarum and Improved Gut Microbiota Composition

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

Across 3 studies, all reported beneficial effects on gut microbiota composition, with moderate effect sizes in two studies and a small effect in one. The only specified population was adults with alcoholic liver disease (ALD) in one study; doses and durations were not consistently reported.

Caveats: Evidence base is small (only 3 studies) and none of the included studies reached statistical significance, so the effect may be smaller than the predominant direction suggests. The overwhelmingly positive results may be influenced by publication bias. One study is a biobank description with no direct outcome data, limiting the strength of the evidence.
