Amino Acids Supplements

Amino acids are the building blocks of protein and play distinct roles in muscle protein synthesis, energy metabolism, and neurotransmitter production. BCAAs (leucine, isoleucine, valine), EAAs (all 9 essential amino acids), and individual amino acids like glutamine, taurine, and beta-alanine each have specific evidence bases. This category cuts through the marketing to explain what the research actually supports and when supplementation makes sense.
