1500mg L-CITRULLINE per 2 Capsules
Applied Nutrition L-Citrulline is a 120-capsule L-citrulline supplement delivering 1500mg of free-form L-citrulline per 2-capsule serving. The 120-capsule bottle provides 60 servings.
L-citrulline is the preferred oral precursor to L-arginine for nitric oxide production. Unlike L-arginine taken orally, citrulline bypasses hepatic arginase metabolism and is converted to arginine in the kidneys, producing a sustained and larger increase in plasma arginine concentration than an equivalent dose of oral arginine. Higher plasma arginine feeds nitric oxide synthase (NOS) in endothelial cells, increasing NO production, driving vasodilation and producing the pump response in resistance training.
At 1500mg per serving, this capsule product delivers a fraction of the 6-8g research-supported dose used in pump pre-workout powders. It is designed as a stackable add-on — not a standalone pump formula. Combining 60 capsules with a pre-workout that already contains 4-5g citrulline adds 1.5g on top for those who want to push total daily citrulline intake without increasing serving size. The capsule format provides precise, flavour-neutral dosing for those who prefer to manage their pump stack independently of pre-workout timing.
L-Citrulline 120 Caps suits trainees who want to fine-tune their nitric oxide stack without switching pre-workouts, or those using a low-citrulline stimulant product who want to add pump capacity separately.
For a powder pump pre-workout that pairs 4g L-citrulline malate with betaine, taurine and beetroot, XL Nutrition Purge Pump 300g delivers 4g L-citrulline malate, 2.5g betaine, 1g taurine and 1g beetroot powder per 10g scoop (stim-free) at £11.99 for 30 servings (just £0.40 per scoop).
