Click for full label (NIH)How to read this
Clinically dosed — the label discloses at least as much berberine per serving as clinical trials used. The black tick on the bar marks the trial dose.
Under clinical dose — the label is honest about the amount, but it's less than the studies used, so the studied effect may not apply.
Dose not disclosed — the label doesn't let you verify the amount at all (usually a "proprietary blend" that only prints the mixture's total weight).
Data verified 2026-07-08 · Scored against: Meta-analyses of RCTs for hyperlipidemia/T2DM report typical doses of 900-1500mg/day; we use the lower bound. How scoring works →
