The bar includes two protein sources with different primary roles. Whey protein concentrate adds milk protein naturally rich in amino acids. It is a common protein choice in snacks aimed at supporting daily protein intake or recovery after physical activity.
Hydrolyzed collagen is collagen that has been broken into smaller fragments. In this product, its role is explicitly noted as helping to give the bar a smooth, dense bite, making it easier to incorporate into the food matrix. This is a functional, textural use common in confectionery and protein products to improve mouthfeel, rather than being the main source of dietary protein. The combination contributes to the overall protein content while achieving the desired treat-like texture that distinguishes it from plainer bars.
