Why it works
Citrulline and arginine are the amino acids the body works with on the pathway toward nitric oxide, which is why they appear together in this category. This is the capsule version of that pairing: 400 mg of L-citrulline DL-malate, 350 mg of L-arginine hydrochloride, and 50 mg of arginine alpha-ketoglutarate in a two-capsule serving, with nothing else but the capsule and a rice-flour filler.
Be clear-eyed about the amount. 800 mg of combined precursors is a low dose for this category, and the training studies people cite for citrulline malate generally use 6 to 8 g. What capsules buy you is convenience and no stimulant: you can take them at any hour, on rest days, or alongside a scoop of our Pre-Workout, which already carries 1,500 mg of arginine AKG of its own.
Benefits
Nitric oxide precursors*
L-citrulline and L-arginine are precursors the body uses on the pathway toward nitric oxide. This serving supports normal nitric oxide production.*
Stimulant-free*
No caffeine and nothing else stimulant, so it can be taken late in the day or on a rest day without affecting sleep.*
Three ingredients, no blend*
Citrulline DL-malate, arginine HCl, and arginine AKG, each listed at its own amount. Nothing is hidden inside a matrix.*
Stacks without duplicating*
It can be taken alongside a pre-workout when you want more precursor without more caffeine, or on its own when you want neither.*
