Lactobacillus rhamnosus and Improved Glycemia

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

Across 3 animal studies, all reported beneficial effects on glycemia, with effect sizes ranging from moderate to large. Only 1 study reached statistical significance. Evidence is derived solely from non-human models; no human studies are available.

Caveats: Evidence base is small (only 3 studies) and all are animal models — conclusions should be considered preliminary. Available evidence is overwhelmingly positive, but clinical literature in this area is subject to publication bias (null-result studies are less likely to be published or indexed). Additionally, many of the included studies did not reach statistical significance, suggesting the effect may be smaller than the predominant direction indicates.
