Description
Arginine is the direct precursor to nitric oxide, but taken alone much of it is broken down in the gut and liver before it reaches circulation. Citrulline bypasses that problem by converting to arginine in the kidneys, raising blood arginine levels more reliably than arginine itself. Combining the two covers both routes.
Jarrow use a sustained-release format so the effect is spread over a longer period rather than spiking and dropping — relevant for vascular health as much as for training performance.
Why the combination:
- Arginine and citrulline together — two routes to nitric oxide
- Supports blood flow, vasodilation and muscle pump
- Vascular and cardiovascular health support
- Sustained-release format for a longer window of effect
- 120 tablets from Jarrow Formulas
Take as directed. Stimulant-free, so it can be used pre-workout or simply as a daily vascular support.
