L-arginine may support cardiovascular health by improving blood flow and lowering blood pressure, primarily by acting as a precursor to nitric oxide (NO), a molecule that relaxes blood vessels. It shows potential benefits for conditions like angina, peripheral arterial disease, and high blood pressure,
How L-arginine benefits cardiovascular health
Increases nitric oxide (NO) production: L-arginine is a key ingredient for the body to produce NO, which helps relax and widen blood vessels (vasodilation), improving blood flow.
Lowers blood pressure: Some studies show that L-arginine can lower blood pressure in healthy individuals and those with mild to moderate hypertension.
Improves symptoms of cardiovascular conditions:
Angina: May help reduce symptoms of chest pain.
