We’re going to break down this supplement to help you decide if it’s one of the best protein powders for you, and also share our proprietary lab data so you can determine if Muscle Milk is all it’s cracked up to be. Let’s get moooo-ving.

Experience Using Muscle Milk 

I had the pleasure of ordering and testing Muscle Milk protein powder, and I went with the Vanilla Crème flavor. I’m a protein smoothie kind of girl, and I find that vanilla-flavored powder mixes best with the fruits and veggies I pile in it (so please don’t come for me because of my basic choice!). I not only tried Muscle Milk in my smoothies, but alone mixed with both milk and water, to get a good sense of how it performs. Here’s what I found.

Price Per Serving

A 1.93-pound jar of Muscle Milk will cost you about $19 on Amazon at the time of this writing, or $1.58 per serving. That’s around average for protein powders, but makes it a great value since each serving of Muscle Milk packs 32 grams of protein. For reference, GGR team favorite Legion Whey+ costs $1.99 per serving but only offers 22 grams of protein, while Optimum Nutrition’s Gold Standard Whey is $1.55 per serving and provides 24 grams of protein.


In each 2-scoop serving of Muscle Milk, you’ll get 32 grams of protein, 21 grams of carbs, and 9 grams of fat. Let’s dig deeper into these nutrition facts. 


The protein content is impressive—good protein powders will typically offer 20 to 25 grams per serving—especially because we know how optimal protein is for building muscle1, particularly in combination with resistance training. 

Muscle Milk’s protein comes from both whey protein concentrate and milk protein isolate. 

RELATED: Best organic protein powder

Whey protein comes from the watery portion of milk that separates from the curd during the cheese-making process, while milk protein comes from—you guessed it—milk. These are both dairy products, so if you’re plant-based or vegan, Muscle Milk won’t be the right fit for you. 

Whey protein is touted as being quickly digested, and the optimal protein for putting on muscle mass 2 as it contains all nine essential amino acids. Amino acids are the building blocks of protein, and there are nine that we must get from our diet since our bodies do not manufacture them.

Whey protein concentrate is the most common form of whey protein, and is cheaper than whey protein isolate. However, whey protein isolate has a significantly higher protein content and is usually easier to digest because it has much less lactose—keep this in mind if you’re sensitive to dairy. 

Milk protein3 is one of the slowest-digesting proteins, containing both casein and whey. Casein4 is known for its slow-digesting properties, and is often used by fitness lovers to help with recovery when taken specifically before bed. The milk protein in muscle milk is in the isolate form, which means that the compound has a 90% protein content.

Carbs and Fat

A typical protein powder will be just that—mostly protein, with not many carbohydrates or fats. Muscle Milk has more carbs—21 grams—and fat—9 grams—than most protein powders, so it’s more similar to a meal replacement, which would provide a good amount of all macronutrients. This is not good or bad, you’ll just have to take this into account for your nutrition plan and goals, particularly if you’re following an approach like macro counting

Vitamins and Minerals 

Muscle Milk also contains quite a few micronutrients, being a good source of calcium (45% RDV), vitamin A, D, and C (35% RDV), and magnesium (50% RDV).

  • The 590 milligrams of calcium5 per serving helps strengthen bones and helps blood vessels move blood throughout the body.
  • The 320 micrograms of vitamin A6 per serving helps support the immune system, vision, and reproductive function, among other things. 
  • The 7 micrograms of vitamin D7 per serving also helps your body build strong bones.
  • The 32 milligrams of vitamin C8 per serving helps to build and repair tissues in your body, including collagen, L-carnitine, and neurotransmitters.
  • Lastly, the 210 milligrams of magnesium9 helps support muscle and nerve function as well as blood sugar levels.

Additional Notable Ingredients 

Muscle Milk isn’t necessarily what we’d call “clean,” utilizing some additives and artificial flavors. It has non-dairy creamer in it (made with sunflower oil), as well as maltodextrin10 (an additive used for thickening and to improve mouthfeel), sodium caseinate 11 (a milk derivative and food additive used as a binder), canola oil, and medium-chain triglycerides, plus acesulfame potassium and sucralose as artificial sweeteners. 

Taste and Solubility 

As mentioned, I tried the Vanilla Crème flavor of Muscle Milk, and overall, I like it. It’s a mild vanilla flavor, but pretty sweet, so if that isn’t your jam, I’d look at a different flavor option. I think the Vanilla Crème flavor would be good for baking, or to put in dishes like oatmeal that could use a little extra protein boost.

What I don’t love about Muscle Milk is that it’s two scoops per serving, and that’s just a lot of powder to dissolve into the recommended 8 ounces of liquid. The fact that it’s a bit chalky doesn’t surprise me, simply because of this. However, even though it is thick, it doesn’t clump when mixed, so it has that going for it. And I will say that when I blend this into a smoothie the consistency is less of an issue. It doesn’t taste like a milkshake necessarily, but it’s pretty good nonetheless.

Side Effects

If you’re lactose-intolerant or sensitive to dairy products, Muscle Milk is a no-go given its dairy content. Also, if you’ve never taken a protein supplement before, you may experience some initial gastrointestinal discomfort as your body gets used to the increased protein. This should subside in a few days. 

Third-Party Testing 

Dietary supplements do not have to be approved by the U.S. Food and Drug Administration (FDA) before being offered for sale, so testing by an independent agency is key to ensure that you’re getting what the product’s label says you are. 

Muscle Milk is NSF Certified for Sport, which means that this protein powder is free from substances banned by major sporting organizations—a key consideration if you’re a competitive athlete. GGR also conducted its own third-party testing with independent, accredited lab, Ellipse Analytics. We tested more than 150 protein powders for purity and label accuracy, and Muscle Milk was rated as Meets Standard overall, which means that it passed our rigorous quality screen.

GGR protein lab testing data scorecard for Muscle Milk Genuine Protein Powder in Vanilla Creme
GGR collaborated with Ellipse Analytics, an accredited third-party lab, to test more than 150 protein powders. We screened for dozens of factors and rated each product against its peers. Excellent indicates the top 10% of products; Above Average is the top 25% of products; and Meets Standard is the top 50%.

We always recommend that you look for a third-party testing logo on your supplements before purchasing them, as this helps mitigate your own personal risk. We tested for heavy metals and protein content, and it’s important to note that just because a contaminant is detected in a product doesn’t make it immediately harmful.

Comparison to Body Fortress Whey Protein  

Body Fortress Whey Protein

Body Fortress Whey Protein

GGR Score: 4.25 starstarstarstarstar

Product Highlights

  • Available in 5 flavors
  • 30 g of protein per scoop
  • Contains vitamins C & D, plus zinc 
  • Mixes well and reportedly tastes good

Pros & Cons


  • High protein content
  • Mixes well
  • Added vitamins for immunity


  • Sucralose can cause GI problems
  • Large serving size
  • Reports of misleading allergen information

Bottom Line

If you do not mind artificial sweeteners or additives in your protein, Body Fortress Super Advanced Whey Protein provides 30 grams of whey protein per 45-gram serving.

Body Fortress is another protein powder with a relatively high protein content—one scoop has 30 grams of protein—and also some carbs and fat at 8 and 4 grams, respectively, per scoop. It only has 180 calories per scoop though, compared to Muscle Milk’s 280.

The protein source in Body Fortress is a mix of whey protein concentrate and isolate, which makes for its lower fat content. There are some additional ingredients, similar to Muscle Milk, like maltodextrin, sunflower lecithin, and acesulfame potassium and sucralose for sweetener. 

GGR head of content and product tester Kate Meier tried the chocolate flavor of Body Fortress whey protein and really liked the taste and consistency. “It’s creamy, not overly protein-y, and very chocolatey.” 

With less carbs and fat and about the same amount of protein, those looking for a leaner protein supplement should go with Body Fortress whey. If you need more nutrients in your protein drink, Muscle Milk is a good choice.

Customer Experience 

While Muscle Milk has a website, you can’t buy directly from it—you’ll need to use a retailer like Amazon, or even your local grocery store, to get your Muscle Milk products. If you’re an Amazon Prime member you’ll get free shipping, and can even take advantage of the subscription option to save 5 to 15% on your order. 

I wasn’t able to find any warranty information, and the return policy will depend on the retailer that you purchased your protein powder from. 

Customer Reviews

Muscle Milk Genuine protein powder has a whopping 13,300 Amazon reviews at the time of this writing with a 4.5-star average rating. 

Customers like the flavor options and versatility, but some did have some issues with solubility and others didn’t like that it was more of a meal replacement shake than a lean protein shake.

Final Verdict of Our Muscle Milk Review

If you’re a super active individual who needs extra nutrients to sustain your training, Muscle Milk could be a suitable option to support muscle growth.

  • With 280 calories per serving, 32 grams of protein, 21 grams of carbs, and 9 grams of fat, this is more of a meal replacement than a solely high source of protein. 
  • This won’t be suitable for vegans or plant-based eaters, or those who are lactose intolerant. 
  • Because Muscle Milk is NSF Certified for Sport, even competitive athletes can consume this without worry.

Muscle Milk Review FAQs

Is Muscle Milk drink good for you?

“Good for you” is a relative phrase, and it really depends on what your goals are. If you’re looking to lose weight, Muscle Milk will not be as good of an option as another protein powder with less carbs and fat. If you’re looking to sustain hard training or even gain weight, Muscle Milk could be a good tool to help you achieve that.

Does Muscle Milk actually work?

Muscle Milk can help support your muscle-building endeavors if utilized in conjunction with a proper nutrition plan and resistance training utilizing progressive overload

Is it okay to drink Muscle Milk every day?

While whole foods are always superior to supplements, sometimes meeting your goal protein intake through food alone is really difficult. In that case, utilizing a protein powder like Muscle Milk daily could be beneficial to your goals—that is, if you don’t have any dairy sensitivities. It’s best to speak with your doctor before you adopt any dietary supplements into your diet. 

What does drinking Muscle Milk do?

In conjunction with strength training and a proper nutrition plan, Muscle Milk can help build muscle by increasing your protein intake.
