L-Arginine is one of the most studied amino acids when it comes to circulation, and for good reason: it's a direct building block for one of the body's own blood-flow signals.
What L-Arginine Actually Does
L-Arginine is an amino acid the body converts into nitric oxide, a molecule that helps blood vessels relax and widen. Healthy blood flow is part of what supports everyday stamina and vitality.
Why It's Paired With Traditional Botanicals
VigorHorse pairs L-Arginine with traditional botanicals like Catuaba, which has its own traditional use for supporting circulation — the modern amino acid and the traditional botanical, addressed together.
