How to read this

Clinically dosed — the label discloses at least as much citrulline 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 2026-07-18 · Scored against: Barkhidarian et al. 2019, Avicenna J Phytomed meta-analysis: significant diastolic-BP reduction only at >=6 g/day L-citrulline; systolic improved across 3-9 g/day. Vascular/blood-flow threshold. Caveats on Method page: dedicated ED trial (Cormio 2011) used 1.5 g/day; citrulline malate is a 2:1 salt whose weight overstates L-citrulline.. How scoring works →
