Lactobacillus rhamnosus and Reduced Inflammation

Research synthesisLow evidenceModerate effect13 studies · 13 beneficial · 0 neutral · 0 harmful

Across 13 studies, 13 reported beneficial effects of Lactobacillus rhamnosus on reducing inflammation, with effect sizes predominantly moderate (11 moderate, 1 small, 1 large). The evidence is strongest in pediatric asthma and chronic kidney disease populations, though study durations and doses were not consistently reported. Only 2 studies reached statistical significance, and most findings are from in vitro or animal models.

  • Studied populations: children and/or adolescents with asthma, patients with non-dialysis chronic kidney disease stage 3-5, participants undergoing oncological treatment, children and adults with allergic diseases

Caveats: 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). Many of the included studies did not reach statistical significance — effect may be smaller than the predominant direction suggests. Most studies are in vitro or animal models; human trial data are limited to a few small or exploratory studies. Doses and study durations are not consistently reported, making it difficult to determine effective regimens.
