Lactobacillus rhamnosus and Reduced Oxidative Stress

Research synthesisLow evidenceModerate effect5 studies · 5 beneficial · 0 neutral · 0 harmful

Across 5 studies, 5 reported beneficial effects of Lactobacillus rhamnosus on reducing oxidative stress, with a predominant moderate effect size. Two of the 5 findings were statistically significant. Evidence is primarily from animal and in vitro models, with no human data available; study durations and doses were not consistently reported.

Studied populations: broiler chickens, mice (with induced intestinal inflammation or UVB exposure), HaCaT cells (in vitro)

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). Evidence base is small (only 5 studies) — conclusions should be considered preliminary. All studies are in non-human models (chickens, mice, cell lines), so direct applicability to humans is uncertain.
