Arginine

Arginine is an amino acid, a building block of proteins needed by the body. It plays a key role in producing nitric oxide, a molecule that helps blood vessels relax and improve blood flow. This can support cardiovascular health, immune function, and wound healing. Arginine is found in foods like meat, nuts, and dairy, and is also available as a supplement. The body naturally produces some arginine, but additional intake may benefit certain health conditions or athletic performance. Overall, arginine is an important nutrient that helps maintain healthy circulation and cellular functions.
