L-Arginine is a precursor to nitric oxide (NO), a molecule that promotes vasodilation (widening of blood vessels). This helps improve blood flow, delivering more oxygen and nutrients to muscles and tissues, which can enhance physical performance and overall cardiovascular health.
By increasing nitric oxide levels, L-Arginine can lead to more pronounced muscle pumps and improved vascularity during exercise. This makes muscles appear fuller and more defined, which is especially beneficial for bodybuilders and athletes seeking better muscle definition.
L-Arginine’s ability to increase nitric oxide production helps improve blood circulation, support healthy blood pressure levels, and enhance overall heart health. It may help prevent conditions related to poor blood flow, such as high blood pressure or arterial stiffness.
