The Active Ingredient Is: Milk Protein

Milk protein provides essential amino acids and plays a key role in supporting normal muscle function and protein turnover. This dairy-derived ingredient is represented by a blend that typically includes whey protein isolate, milk protein, and whey powder.

This form is sourced from milk and is commonly used to help meet daily protein needs and support muscle recovery as part of a balanced diet.

What Does Milk Protein Do?

Milk protein helps maintain normal muscle function and supports satiety within a calorie-conscious eating plan. It plays a role in providing high-quality protein to the body, which is aligned with EFSA and NHS guidance on nutrient function.

It contributes to protein intake after activity and supports ongoing tissue maintenance as part of a healthy lifestyle.
