BCAA and EAA supplements have become the intra and post-workout staples of fitness enthusiasts and bodybuilders. And for very good reason; they stimulate protein synthesis, boost nitrogen, reduce the loss of lean muscle tissue after strenuous exercise, along with speed up recovery time and aid muscle growth and repair.

BCAAs are the essential amino acids that obtained their name “branched-chain” due to their unique branch-like structure. The three branched-chain amino acids are:

  • Leucine
  • Isoleucine
  • Valine

The nine essential amino acids are:

  • Leucine (BCAA)
  • Isoleucine (BCAA)
  • Valine (BCAA)
  • Histidine
  • Lysine
  • Methionine
  • Phenylalanine
  • Threonine
  • Tryptophan


All BCAAs are EAAs, but not all EAAs are BCAAs. But which is better? BCAAs or the more complete EAAs? Comparatively, both are vital for muscle building and repair when the muscles are recovering so it’s not to say that the benefits of the one make the other redundant.

However, more recently many supplement companies are overselling the idea that BCAAs are all that are needed for optimal muscle growth. The truth is that you need all nine essential amino acids to build muscle. BCAA (Leucine, isoleucine and valine) provide just three pieces of the nine-piece puzzle.

In a sense, you can look at BCAAs as the “ON” switch that activates muscle protein synthesis engine and the other six essential amino acids keep the engine running.  BCAAS are the “ignition switch” while EAAs are the actual fuel that “keeps the motor running”. To put it even simpler, BCAAs without EAAs present will not drive muscle growth.

NPL’s Amino Armour is the perfect all-in-one amino acid powerhouse. It provides essential amino acids (EAAs) including the BCAAs Leucine, isoleucine and valine as well as Tyrosine and Taurine to maximise your body’s anabolic response
