Amino acid studied for nitric oxide and blood flow, vascular support, exercise. How it works, the dose and timing studied, what it interacts with, and the research behind the grade.
All compoundsA direct substrate for nitric oxide synthase, supporting vasodilation and blood flow. Much of an oral dose is degraded in the gut and liver, making citrulline a more reliable way to raise arginine levels.
The dose below reflects the range used in published research. Match the form alongside the milligrams. Set your own wake and bed times to map the timing onto your day.
