The Active Ingredient Is: Whey Protein (Whey Protein Concentrate)

Whey protein is a high‑quality dairy protein that provides all essential amino acids necessary for normal body functions and tissue maintenance. This form is derived from milk and is commonly available as whey protein concentrate, offering a rich profile of amino acids for supporting everyday protein needs.

In mass‑gain formulations, whey protein concentrate supplies a complete amino acid matrix that supports muscle and metabolic processes. This formula also includes carbohydrate sources to help meet energy targets for training, while flavourings aid palatability.

What Does Whey Protein Do?

Whey protein assists with muscle protein synthesis and supports recovery as part of an active lifestyle, contributing to normal muscle maintenance and strength support.

It plays a role in providing essential amino acids that contribute to energy balance and overall protein availability for daily physiological processes. This information aligns with general nutritional guidance on protein function.
