L-Arginine is a semi-essential amino acid that plays a key role in nitric oxide production, which helps dilate blood vessels and improve blood flow. This makes it a popular ingredient in supplements aimed at enhancing exercise performance, muscle pumps, and cardiovascular health.
L-Arginine also supports immune function, wound healing, and hormone production. It is often used by athletes to improve endurance and recovery.
While L-Arginine is generally safe, excessive intake may cause gastrointestinal issues or low blood pressure.
