Summary
This protein powder contains high-quality whey protein isolate, which is beneficial for muscle repair and growth. However, the presence of sucralose, an artificial sweetener, and artificial flavors detracts from its overall healthiness. Additionally, the use of soy lecithin as an emulsifier and the inclusion of both natural and artificial flavors indicate a moderate level of processing, which impacts the score.
