Lactobacillus rhamnosus LRa05 and Improved Glycemia

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

Across 3 studies, all reported beneficial moderate-sized effects of Lactobacillus rhamnosus LRa05 on glycemia. One randomized controlled trial (n=80 adults with T2DM) found statistically significant reductions in glycated hemoglobin and fasting plasma glucose. The evidence base is small and preliminary, with limited dose and duration data.

Studied populations: adults with type 2 diabetes

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). Most studies did not report dose or duration, making replication difficult.
