How to choose the right BCAA supplement

BCAAs (Branched-Chain Amino Acids) are vital for muscle recovery, but not all BCAA supplements are created equal.

  • Look for the right ratio: 2:1:1 (Leucine:Isoleucine:Valine) is the most common and effective ratio.
  • Consider the flavor: If you prefer a neutral taste, go for unflavored options.
  • Check for additional ingredients: Some supplements include L-Glutamine or Citrulline to further support recovery.
