The Active Ingredient Is: Essential Amino Acids

Essential amino acids are the building blocks that the body cannot synthesise, and they are required for normal protein production and tissue maintenance.

In this blend, essential amino acids sit alongside other amino acids to help muscle recovery and growth, with an emphasis on quick absorption and availability from the formula.

What Do Essential Amino Acids Do?

Essential amino acids help with muscle protein synthesis and everyday recovery processes, aiding in keeping lean tissue maintained. This aligns with EFSA guidance on amino acid function in healthy adults.

Dr. Wolfe of Harvard University found that EAAs help stimulate muscle protein synthesis, supporting recovery when taken around exercise as part of a balanced diet.
