The terms “muscle milk” and “whey protein” are mostly used interchangeably. However, although these products are both rich in protein, they are far from being the same. This article provides valuable information on the differences between the two.
Muscle Milk is a protein supplement available in powder, oatmeal, bar, and ready-to-drink liquid forms. Manufactured by CytoSport, Inc., Muscle Milk is sold in low-caloric packages. It powers up the body by supplementing it with different types of protein such as whey hydrosalate, whey concentrate, and casein.
Ideally used as a meal replacement or a pre-workout supplement, a 14-ounce serving of Muscle Milk contains approximately 20 to 25 grams of protein.
Whey protein, on the other hand, is a powdered protein supplement available in hydrolysate, isolate, and concentrate variants. The whey concentrate determines the amount of protein in each variant. Among the three, whey concentrate has the least protein concentrate at approximately 70% to 80%.
Used as a pre-workout or post-workout protein supplement, a single serving of whey isolate protein contains around 25 grams of protein.
Muscle Milk vs Whey Protein
So what’s the difference between Muscle Milk and whey protein? Even though both products are rich in protein, they are completely different in a number of ways.
Firstly, Muscle Milk is a product line released by CytoSport, Inc., while whey protein is a protein supplement manufactured by several companies. Whey protein is only available in powdered form but Muscle Milk offers more variety to consumers since it is available in the forms of powder, bar, oatmeal, and ready-to-drink liquid.
Whey protein is mostly made up of whey protein, which is easily absorbed by the body. Muscle Milk, on the other hand, is a blend of different types of protein such as whey hydrosalate, whey concentrate, whey isolate, and casein, which break down slower than other protein types.
In terms of protein content, whey protein powder’s protein concentration is largely dependent on its variant. Whey protein is available in three types: hydrolysate, isolate, and concentrate. Protein concentrate and isolate powders contain approximately 70% and 90% protein by weight, respectively. Muscle Milk, by contrast, only contains around 45% protein by weight.
Ideally used as a meal replacement or a pre-workout supplement, Muscle Milk is typically higher in calories, carbohydrates, and fats. On the other hand, whey protein is not a recommended substitute for meals. Instead, it mainly functions as a pre-workout or post-workout protein supplement.
Muscle Milk and whey protein are also distinct in taste. As a well-known protein supplement, Muscle Milk is made with more flavorings and additives for taste enhancement. Meanwhile, whey protein’s flavor is highly dependent on the ingredients used by the manufacturer. Frequently, whey protein is less palatable than Muscle Milk.
Lastly, since Muscle Milk and whey protein are made with different ingredients, they are sold at different price points. Muscle Milk is typically pricier than whey protein powder.
