Arginine supplements provide L-arginine, an amino acid that helps your body produce nitric oxide, which improves blood flow. It’s commonly used by people looking to support heart health, enhance workout performance, or improve circulation. Whether you're an athlete chasing better endurance or someone focused on cardiovascular support, arginine is a simple, effective addition to many supplement routines.
