African Mango and Reduced Waist Circumference

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

Across 3 studies, all reported beneficial effects of African mango (Irvingia gabonensis) seed extract on waist circumference, with predominantly small effect sizes. The most studied population is overweight and obese adults, and effects were typically observed at 90 days (median duration). One study used 150 mg twice daily, but dose reporting is limited.

  • Effective dose range: 150 mg twice daily (limited evidence)
  • Studied populations: overweight and obese adults, individuals with metabolic syndrome

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. Only one study reported a specific dose; dose-response data are lacking.
