Milk Isolate
Micellar Casein
Whey Concentrate
Whey Isolate
Hydrolized Whey

While the sources of protein are good, the protein content only makes up 61% of the protein volume.

There are a few ingredients that may raise some concern, such as artificial flavors and artificial sweeteners such as sucralose and Acesulfame Potassium. Unfortunately the product does not contain any digestive enzymes, which could have aided in the breakdown and absorption of the protein.

Watchlist Ingredients



With 50 grams of protein per serving, this product contains both fast and slow-absorbing protein that is effective in delivering protein to support muscle growth and recovery.

The combination of the included protein blend makes this an ideal once-a-day supplement to take after a workout. The bulk of fast-digesting protein is absorbed directly when needed after the workout while the slow-digesting protein keeps a steady supply going throughout the day or night depending on your timing.


However, the protein blend is not as high-quality as some other products on the market, which may impact its overall effectiveness in comparison. This is because the cheaper and less processed forms of whey are listed first as being in the highest quantity. This is not necessarily a bad thing as it helps keep costs down while providing a balanced approach.



The Knockout Chocolate flavor has a smooth and rich taste, similar to a chocolate milkshake, making it an enjoyable product to consume. However, we noted that the powder can take a bit of extra effort to mix well and a blender or shaker bottle is a must for this powder.



The price of this product is actually reasonably on par for the included ingredients when compared to other protein supplements on the market.

Relative Cost

However, we think the quality of the ingredients and the lack of digestive enzymes does impact its overall value a little. That said, this is a tasty product that packs a hefty-sized protein punch and may suit your routine at a reasonable value.



Muscle Milk Pro Series Protein is a solid choice for those looking to supplement their protein intake. The balanced blend of fast and slow-absorbing protein in high quantity makes it an ideal general supplement to support your fitness goals. The taste is fantastic, making it an enjoyable addition to your fitness routine. While it may not be the most affordable option on the market, the overall value of this product is still quite good. All things considered, Muscle Milk Pro Series Protein is a good choice for those who prioritize a broad protein blend and a delicious taste. A good product for beginners that aren't yet familiar with timing protein intake perfectly based on individual protein types.
