Okra and Reduced Fasting Blood Glucose Levels

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

Across all 3 studies, okra supplementation consistently shows beneficial and statistically significant reductions in fasting blood glucose levels. Effect sizes range from moderate to large, with mean reductions of approximately 15–40 mg/dL reported in meta-analyses of clinical populations (pre-diabetes and type 2 diabetes). The most-studied dose is ≤3,000 mg/day, but median study duration was not consistently reported.

  • Effective dose range: ≤3,000 mg/day
  • Studied populations: people with pre-diabetes or type 2 diabetes

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). Study durations not consistently reported, making it unclear how long supplementation is needed for the observed effect.
