It is commonly used to boost athletic performance, improve blood flow, and reduce fatigue, with potential benefits extending to supporting cardiovascular health and erectile dysfunction. L-Citrulline supplements are often preferred over direct L-arginine supplementation for better absorption and efficacy.
