The Core Ingredient Is: Whey Protein (Multi-Source Blend)

Whey protein is a solid protein source that provides essential amino acids needed for normal bodily functions and muscle maintenance.

This formula blends fast- and slow-digesting proteins, helping to supply a steady stream of amino acids from whey isolates, hydrolyzed whey, micellar casein, and plant protein to help support everyday vitality.

What Does Whey Protein Do?

Whey protein helps the normal process of muscle protein synthesis after exercise, helping to maintain and repair muscle tissue as part of a balanced diet. It also contributes to feelings of fullness after meals, supporting daily energy balance.

Scientific research suggests post-exercise protein intake can stimulate anabolic processes, contributing to muscle recovery and satiety. This aligns with EFSA-style guidance on high-quality protein consumption and normal bodily functions. Dr. Morton of the University of Leeds found that protein intake after exercise helps to support muscle protein synthesis.
