best amino acids supplements for muscle definition
Amino acids are best known for their role in building muscle and strength in athletes, in particular: 1  BCAAs (branched-chain amino acids L-leucine, L-isoleucine and L-valine), which are valuable building blocks for muscle tissue growth and repair, 2  L-arginine, which improves blood flow (âPumpâ),
Amino acids are especially important, because they are the building blocks of protein, which makes up muscle tissue. Especially L-leucine and Taurine are important for the continuous growth and avoidance of breakdown of muscle tissue.
