Muscle Milk Pro Series Protein and Optimum Nutrition Gold Standard 100% Whey are both popular protein powders designed to support muscle growth and recovery. They share a common purpose of providing high-quality protein sources that are quickly absorbed by the body. However, there are some key differences. Muscle Milk Pro Series Protein contains a blend of milk protein isolate, calcium caseinate, whey protein concentrate, and whey protein hydrolysate, and offers a whopping 50g of protein per serving. On the other hand, Optimum Nutrition Gold Standard 100% Whey uses a blend of whey isolate, whey concentrate, and hydrolyzed whey peptides, providing 24g of protein per serving. Muscle Milk Pro Series Protein contains artificial flavors and sweeteners, while Optimum Nutrition Gold Standard 100% Whey has a shorter list of ingredients and is significantly short on additives.
We recommend Optimum Nutrition Gold Standard 100% Whey as the superior product. While Muscle Milk Pro Series Protein offers a high amount of protein per serving, Optimum Nutrition Gold Standard 100% Whey stands out due to its balanced blend of different forms of whey and fewer additives. It provides a well-rounded protein supplement that is ideally suited for post-workout recovery or as a meal replacement. Despite offering less protein per serving, the quality of the protein and the overall formulation of Optimum Nutrition Gold Standard 100% Whey make it our top recommendation.
