Bifidobacterium animalis subsp. lactis LAFTI B94 and Reduced Gastrointestinal Symptoms

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

Across 3 studies, all reported beneficial effects on reduced gastrointestinal symptoms, with effect sizes ranging from small to moderate (predominantly moderate). However, no studies reported statistically significant findings. The evidence is drawn from review articles, primarily in athletic populations, with no specific dose or duration reported.

  • Studied populations: athletes and physically active adults

Caveats: Evidence base is small (only 3 studies) — conclusions should be considered preliminary. All three studies are review articles, not primary clinical trials, and none reported statistically significant findings. The overwhelmingly positive direction may reflect publication bias, as null results are less likely to be published.
