supplements for endothelial dysfunction
Endothelial function, the ability of blood vessel linings to regulate circulation, is a foundational marker of cardiovascular health, and clinical research shows several supplements can measurably improve it. This guide reviews the strongest evidence behind nitric oxide supporters such as L-citrulline and L-arginine, antioxidants including vitamin C, CoQ10, and omega-3s, and botanicals like pomegranate and pine bark extract. Each section explains the mechanism, grades the evidence, and lists typical doses and safety considerations. A comparison table and food-first alternatives help you identify which options may be worth discussing with your healthcare provider.
