The Active Ingredient Is: Essential Amino Acids

Essential amino acids are the core pieces your body can't make on its own, so you grab them from food or supplements, and keep going. This product supplies a full group of EAAs in a handy powder you can mix to back up normal protein synthesis.

This formula brings together a mix of essential amino acids that are easy to shake up and quick to absorb, which helps with ongoing tissue repair and protein assembly.

What Do Essential Amino Acids Do?

Essential amino acids help with muscle protein synthesis and skeletal muscle repair, supporting recovery after workouts. Research suggests these acids help keep normal muscle function and may influence post-exercise recovery, and Dr. Tipton from the university noted that amino acids taken around activity can boost muscle protein synthesis.

The mix of EAAs, including the branched-chain amino acids, helps back up the body’s normal protein-building processes and hydration-related muscle function, in line with EFSA guidance.
