L-Arginine L-arginine, an amino acid with various physiological roles, including as a precursor to nitric oxide (NO), facilitates vasodilation and improved blood flow, supporting cardiovascular health, exercise performance, erectile function, and wound healing. | Beta-Alanine Beta-alanine, a non-essential amino acid, facilitates the production of carnosine, which functions as a buffer against muscle acid buildup during high-intensity exercise, delaying fatigue and enhancing performance, especially in activities requiring short bursts of intense effort. | L-Theanine L-theanine, found primarily in tea leaves like green tea, promotes relaxation without drowsiness by enhancing neurotransmitter production, including GABA, serotonin, and dopamine, leading to reduced stress, improved focus, and potential benefits for sleep and cardiovascular health. | BCAA Branched-chain amino acids (BCAAs), comprising leucine, isoleucine, and valine, are essential nutrients vital for muscle growth, reduced soreness, increased endurance, fatigue reduction, and lean muscle preservation, commonly supplemented by athletes and fitness enthusiasts. |
