The Fantastic Nine

There are nine EAAs :

  • Valine: Boosts muscle growth and tissue repair.
  • Leucine: Essential for protein synthesis and muscle recovery.
  • Isoleucine: Helps in resistance, muscle repair and sugar regulation.
  • Lysine: Crucial for collagen formation and calcium absorption.
  • Methionine: Important for metabolism and detoxification.


  • Phenylalanine: Neurotransmitter precursor, improves mood.
  • Threonine: Key to the production of collagen and elastin.
  • Tryptophan: Necessary for the production of serotonin, it influences sleep.
  • Histidine: Vital for tissue growth and repair.

EAA vs BCAA: The Key Difference

  • BCAAs (branched-chain amino acids) are a subset of EAAs and include leucine, isoleucine, and valine .
  • While BCAAs are great for muscle protein synthesis , we shouldn't forget the power of the other six EAAs. All together they make an invincible team!
