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

Branched-Chain Amino Acids, comprising L-leucine, L-isoleucine and L-valine, are essential nutrients that support muscle protein turnover and normal muscle function.

This powder form provides BCAAs in a 2:1:1 ratio, with the three amino acids contributing to metabolic processes involved in exercise and recovery.

What Does Branched-Chain Amino Acids Do?

Branched-Chain Amino Acids play a role in muscle protein synthesis and may help support recovery and reduce post-exercise soreness, aligning with guidance from EFSA and NHS perspectives. Dr. Jäger of the University of Rostock found that a 2:1:1 BCAA ratio can support recovery in active individuals.

The combination of L-leucine, L-isoleucine and L-valine also participates in amino acid metabolism and energy production during physical activity, helping maintain normal function during and after exercise.
