Lactobacillus salivarius UCC118 and Improved Insulin Sensitivity

Research synthesisHigh evidenceModerate effect6 studies · 6 beneficial · 0 neutral · 0 harmful

Across all 6 studies available in the database, the evidence consistently shows beneficial effects of Lactobacillus salivarius UCC118 on insulin sensitivity. The predominant effect size is moderate, with 4 of the 6 studies reporting statistically significant improvements. The most-studied populations are pregnant women and those with gestational diabetes mellitus. No specific effective dose range could be identified due to inconsistent reporting.

  • Studied populations: pregnant women, women with gestational diabetes mellitus

Caveats: The available evidence is drawn primarily from meta-analyses and reviews that assess probiotics broadly, not specifically Lactobacillus salivarius UCC118. Exact dosing information is lacking in the reported studies, which limits precision. All studies focus on metabolic changes in pregnancy-related populations, so generalizability to other groups is uncertain.
