saccharomyces boulardii and Reduced Abdominal Distension

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

Across 3 studies, all reported beneficial effects of Saccharomyces boulardii on reducing abdominal distension, with effect sizes ranging from moderate to large. The evidence is drawn from meta-analyses primarily in children and patients with Helicobacter pylori infection. Doses were not consistently reported, but one study used 500 mg/day or 1000 mg/day.

  • Studied populations: children with Helicobacter pylori infection; patients with Helicobacter pylori infection

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). Study durations were not consistently reported, limiting assessment of time-to-effect.
