This formula also includes metabolic support ingredients such as L-Carnitine, green tea extract and caffeine, which help to complement protein delivery and overall lean-muscle goals.

What Does Whey Protein Isolate Do?

Whey protein isolate helps to provide high-quality amino acids for normal body functions and daily protein intake, supporting muscle maintenance and tissue turnover. It is presented in a highly digestible form to support ongoing protein availability throughout the day.

The protein component works within a broader formula that includes vitamins and metabolic ingredients to support energy metabolism and nutrient utilisation, aligning with EFSA-guided understanding of protein’s role in healthy physiology.
