The Active Ingredient Is: Whey Protein

Whey protein is a high-quality dairy protein containing all essential amino acids necessary for normal body functions.

This form is commonly sourced from milk and is used in meal replacements to support satiety and lean muscle maintenance as part of a balanced diet.

What Does Whey Protein Do?

Whey protein participates in supporting muscle mass during energy restriction and helps maintain fullness, contributing to appetite control in line with EFSA guidance. UK health guidance also emphasises the role of adequate protein in a balanced diet.

Evidence suggests protein-rich meals can support weight management when combined with overall energy balance.
