L-Citrulline Malate

Why it earns a place
Raises nitric oxide for better blood flow — a few extra reps per set and less next-day soreness.
Who it's for
Lifters chasing volume and endurance athletes doing hard intervals.
Who should skip it
You take blood pressure or erectile dysfunction medication without clearing it with your doctor first.
Dose
6–8g citrulline malate (or 3–4g pure L-citrulline).
Timing
30–45 minutes before training.
Typical price
$20–$35
Common questions
Citrulline or arginine?
Citrulline. Arginine is largely broken down in the gut before it raises nitric oxide, which is why the research moved on.
Do I need it on rest days?
No. It's a training-day tool, unlike creatine which you take daily.
