The ingredient most central to Vasoryn's own explanation of how it works, with no dose disclosed.
L-Citrulline is the first step in the mechanism Vasoryn's own materials describe: citrulline survives liver metabolism better than arginine itself, gets converted to arginine, which becomes the substrate for nitric oxide, which relaxes vessel walls and affects vascular tone.
Typical studied intakes of L-Citrulline used in circulation and blood-pressure-related research run around 3,000mg (3g) daily on their own.
Vasoryn's entire proprietary blend, all six undisclosed ingredients combined, totals 570mg — meaning even if citrulline made up the whole blend, it would still fall well short of that commonly studied amount. We don't know what portion of the 570mg it actually represents.
