The Active Ingredient Is: Branched-Chain Amino Acids (BCAAs)

Branched-chain amino acids are essential amino acids that help support muscle protein synthesis and energy supply during intense exercise sessions. This formula includes a BCAA blend along with other amino acids to help support training endurance and faster recovery after workouts.

What Does Branched-Chain Amino Acids (BCAAs) Do?

BCAAs contribute to everyday muscle recovery processes and participate in reducing biomarkers of muscle damage after intense training, helping support post-exercise recovery as noted in scientific discussions from Liverpool John Moores University.

This supplement’s BCAAs are linked with a reduction in muscle soreness and improved recovery, aligning with EFSA-style mechanisms for amino acid support that researchers often cite.

This supplement is not designed to diagnose, treat, cure, or prevent any disease.
