The Active Ingredient Is: Whey Protein Isolate

Whey Protein Isolate is a high-purity dairy protein derived from milk, valued for rapid digestion and a rich amino acid profile.

This form is sourced from grass-fed cows and processed to maximise protein content while minimising fat and lactose, making it suitable for post-workout nutrition and lean muscle support.

What Does Whey Protein Isolate Do?

Protein plays a key role in normal muscle function and maintenance, contributing to the growth and maintenance of muscle mass as recognised in EFSA guidelines.

It is rapidly absorbed, delivering essential amino acids to tissues involved in recovery and supporting muscle protein synthesis following exercise, with low lactose content aiding tolerance.
