Kefir and Reduced Fasting Blood Glucose Levels

Research synthesisLow evidenceModerate effect3 studies · 2 beneficial · 1 neutral · 0 harmful

Across 3 meta-analyses, 2 reported beneficial moderate-sized effects on reducing fasting blood glucose (FBS), while 1 found no significant effect. The beneficial studies observed reductions of approximately 8–10 mg/dL (p < 0.01), but the evidence base is small and no consistent dose or duration was reported.

Caveats: Evidence base is small (only 3 studies) — conclusions should be considered preliminary. Two of the three meta-analyses reported significant benefits, but the third (largest, with 314 participants) found no effect on FBS, introducing uncertainty. Doses and study durations were not consistently reported, limiting ability to recommend specific regimens.
