Intervention · INT-BERBERINE

Berberine

Human trials and meta-analyses report mixed, generally small anthropometric effects. Product quality and study heterogeneity materially limit confidence.

Dietary supplement ingredientPlant-derived alkaloid; proposed metabolic pathways are not a substitute for clinical outcomesLow to moderate evidence

Evidence question

Does berberine meaningfully reduce body weight?

Result / effect

Published syntheses disagree: one 2020 meta-analysis reported no significant body-weight change, while another reported an average reduction of about 2.1 kg.

Evidence chain

Population

Adults enrolled in heterogeneous randomized trials, often with metabolic conditions and varying background care.

Endpoint

Body weight, BMI, waist circumference, and glycemic or lipid markers.

Evidence level

Low to moderate. Conflicting syntheses, variable preparations, small trials, and heterogeneous populations lower certainty for a weight-loss claim.

What this record does not establish

  • Supplement composition and purity may differ from products used in trials.
  • Meta-analyses reach conflicting conclusions for body weight.
  • Drug interactions and adverse effects are not resolved by an efficacy estimate.

Linked study records

This seed record currently synthesizes linked review evidence; no standalone landmark-study record is included in v0.1.
