Summary

This protein powder contains a blend of high-quality proteins such as whey protein isolate, micellar casein, and milk protein isolate, which are beneficial for muscle growth and maintenance. However, the presence of artificial sweetener sucralose and several additives like cellulose gum and sunflower lecithin slightly detracts from its overall health profile. The use of natural flavors, which lack transparency, also contributes to a moderate processing level, impacting the score.
