Lactobacillus acidophilus L-92 and Improved Gut Microbiota Balance

Research synthesisLow evidenceMixed effect size6 studies · 6 beneficial · 0 neutral · 0 harmful

Across 6 review studies, all reported beneficial effects on gut microbiota balance, with effect sizes split evenly between moderate (3 studies) and small (3 studies). No statistically significant findings were reported, and no specific dose or duration data were available.

Caveats: All included studies are narrative reviews rather than original clinical trials; none reported statistically significant findings. 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). Effect sizes were small to moderate, and no specific dose or duration data were provided.
