African Mango and Reduced Waist Circumference

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

Across 3 studies, all reported beneficial small-sized effects of African mango (Irvingia gabonensis) seed extract on reduced waist circumference. The most commonly studied dose was 150 mg twice daily, and effects were observed in clinical populations (e.g., adults with metabolic syndrome or overweight/obesity). The median study duration was 90 days based on one study that reported it.

  • Effective dose range: 150 mg twice daily
  • Studied populations: Adults with metabolic syndrome and overweight/obese individuals

Caveats: 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). Evidence base is small (only 3 studies) — conclusions should be considered preliminary. One included RCT had a small sample size (n=24), which may limit generalizability.
