An amino acid your body uses to make nitric oxide, which supports blood flow.
L-arginine is an amino acid, one of the building blocks of protein. Your body uses it to produce nitric oxide, a molecule that helps blood vessels relax and supports healthy circulation.
Because healthy blood flow plays a role in male vitality and stamina, L-arginine is a common ingredient in this category. It's found naturally in foods like meat, dairy and nuts, and is also available as a standalone supplement.
In VigorHorse, L-arginine is one of eight named ingredients working together, rather than a stand-alone high-dose formula.
