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).

No — the label discloses 400 mg of berberine per serving, below the 900 mg/day clinical dose. You'd need more than one serving to match the studied amount.
Clinically dosed, no-blend options include: Absorb Health Berberine 450 mg (900 mg); Mental Refreshment Berberine HCl 900 mg (900 mg); SuperSmart Berberine 1000 mg (1 g). All disclose at least 900 mg per serving on the label.
