Lactobacillus acidophilus L-92 and Improved Glycemic Control

Research synthesisVery low evidenceModerate effect3 studies · 3 beneficial · 0 neutral · 0 harmful

Across 3 studies, all reported beneficial effects of Lactobacillus acidophilus L-92 on glycemic control, with a moderate effect size observed in the highest-quality study (a network meta-analysis). The evidence base is very small, with only 1 of 3 studies reaching statistical significance. Study durations, doses, and forms were not consistently reported, limiting the ability to identify an optimal regimen.

Studied populations: patients with type 2 diabetes mellitus (T2DM)

Caveats: Evidence base is small (only 3 studies) — conclusions should be considered preliminary. Available evidence is overwhelmingly positive (all 3 studies report benefit) but clinical literature in this area is subject to publication bias. Only 1 of 3 studies achieved statistical significance, and the beneficial study that did not report significance may have weaker effects. No dose, form, or duration data were extracted from the included studies, preventing identification of an effective regimen.

the inhibition of α-glucosidase activity increased by 2.0- to 3.0-fold in fermented S. fusiforme, whereas the inhibition of α-amylase activity was only significantly augmented by the PF-2 and PF-3 strains.
