Lactobacillus salivarius UCC118 and Reduced Prevalence of Gestational Diabetes Mellitus

Research synthesisModerate evidenceModerate effect4 studies · 4 beneficial · 0 neutral · 0 harmful

Across 4 studies (3 meta-analyses, 1 review), all reported beneficial moderate-sized effects of probiotic supplementation on reducing gestational diabetes mellitus (GDM) risk, with 2 meta-analyses finding statistically significant reductions. The evidence primarily comes from analyses of multiple probiotic strains in pregnant women, not specifically L. salivarius UCC118.

  • Studied populations: pregnant women

Caveats: The meta-analyses included various probiotic strains, not solely L. salivarius UCC118, so the specific effect of this strain is unclear. 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).
