An amino acid that supports the body's nitric oxide production, associated with healthy blood flow.
L-Arginine is a naturally occurring amino acid the body uses as a direct precursor to nitric oxide, a molecule that signals blood vessels to relax and widen.
It supports VigorJelly's blood-flow layer, working alongside Horny Goat Weed on circulation.
L-Arginine's role in the nitric oxide pathway is one of the more established mechanisms in circulation research.
This describes general research on L-Arginine itself, not the finished VigorJelly product, which hasn't been the subject of its own clinical trial. See the full ingredients list or the formula overview for more.
