Evidence

Resistance exercise repetitions to failure
Resistance-trained adults • Systematic review & meta-analysis
Moderate

Significant benefit for total repetitions to failure vs. placebo (SMD = 0.20, p = 0.036) with citrulline malate; 8 g acutely prior to upper/lower body resistance exercise.

Dose: 8000 mg • Duration: Acute (single dose pre-exercise)
Citation: Trexler ET et al. Eur J Sport Sci. 2021;21(9):1229–1238.
Pérez-Guisado & Jakeman 2010 RCT (PMID 20386132) found ~52% more bench press reps with 8 g CM vs. placebo.
Aerobic exercise performance / oxygen kinetics / RPE
Recreationally active and trained adults • Systematic review & meta-analysis
Moderate

Positive impact on aerobic performance outcomes including lactate, VO2 kinetics, and perceived exertion via nitric oxide-mediated vasodilation; results mixed, effect sizes small.

Dose: 6000 mg • Duration: Acute to 7 days
Citation: Viribay A et al. Nutrients. 2022;14(17):3479.
Ergogenic effects more consistent for resistance than large-muscle endurance tasks.
Systolic blood pressure reduction
Adults; mixed health status (8 trials) • Systematic review & meta-analysis
Moderate

Pooled reduction of −4.1 mmHg systolic BP (95% CI −7.94 to −0.26); diastolic reduction significant only at ≥6 g/day.

Dose: 6000 mg • Duration: 1–17 weeks
Citation: Barkhidarian B et al. J Hum Hypertens. 2019;33(1):10–21.
Antihypertensive effect modest; most consistent with doses ≥6 g/day.
Forms
Citrulline malate (2:1)
Most common form in sports research; 8 g CM ≈ 5 g L-citrulline.
L-citrulline (pure)
Higher citrulline content per gram.
