The Active Ingredient Is: Branched-Chain Amino Acids (BCAAs) in a 2:1:1 ratio

Branched-chain amino acids are essential amino acids that play a role in muscle protein synthesis and recovery after exercise.

This formula also includes L-glutamine, L-citrulline, coconut water powder and an electrolyte blend, which support hydration and fluid balance during activity.

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

BCAAs are involved in stimulating muscle protein synthesis and may help support lean muscle preservation after training; leucine is particularly involved in this process. This mechanism aligns with guidance from EFSA and NHS-linked overviews on amino acid function. Studies show BCAAs can support muscle recovery and endurance-related processes when consumed around training times.

Dr. Martins of a leading university reported that oral BCAAs promote muscle recovery and support lean muscle maintenance in athletes, highlighting the role of the 2:1:1 ratio in this effect.
