Lactobacillus acidophilus L-92 and Improved Glycemic Control

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

Across 3 studies, all reported beneficial moderate-sized effects of Lactobacillus acidophilus L-92 on glycemic control. One study, a network meta-analysis of 62 patients with type 2 diabetes, found a statistically significant reduction in HbA1c (MD = -1.59; 95% CI: -3.07 to -0.12) using a multi-strain probiotic. Evidence is preliminary due to the small number of studies and lack of consistently reported doses, forms, or study durations.

  • Studied populations: patients with T2DM

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). Doses, forms, and study durations were not consistently reported, limiting the ability to determine specific dosing recommendations.
