The Main Ingredient Is: Whey Protein (Concentrate and Isolate Blend)

Whey protein is a sturdy dairy protein containing all essential amino acids to support muscle function and tissue upkeep. This blend uses whey protein concentrate and whey protein isolate to provide a full amino acid lineup from milk sources such as Lactomin ingredients.

This form combines concentrate and isolate proteins to deliver a versatile protein source derived from dairy, providing rapid and sustained amino acid availability after intake.

What Does Whey Protein Do?

Whey protein helps maintain normal muscle protein turnover by supplying essential amino acids, supporting post‑exercise recovery and muscle repair in line with recognised guidance from EFSA and NHS discussions of protein function.

Dr. Phillips of McMaster University found that whey protein activates the mTOR pathway, aiding muscle protein synthesis and supporting muscle maintenance after resistance activity.
