1.  What is it: A Closer Look at Muscle Milk

Muscle Milk, a brand of non-dairy shakes, is available in powdered and ready-to-drink supplements. While protein is the main ingredient, a scoop of the supplements contains 9 grams of carbohydrates, 2 grams of dietary fiber, and 17 different vitamins and minerals.

Contrary to the name, Muscle Milk does not contain milk, but, it has milk derivatives– whey and casein, probably the reason why it is ideal for people with lactose intolerance.

A brand rich in protein for promoting lean muscles growth and repair.

2. History of the Brand

CytoSport, founded in 1998, is behind Muscle Milk brand, launched in 2000. The idea behind Muscle Milk was to provide a lactose-free protein shake that closely resembles human milk. The whey and casein blend supplements not only help to build muscle, but also provide energy.

In Canada, the supplements are branded as Muscle Milk to avoid confusion with milk.

3. Type of Products

4. Muscle Milk Ingredients

Cytosport Inc. has compiled a blend of ingredients to enhance muscle building. Let’s debunk  some of the main ingredients:

  • Whey Protein

Whey protein is a byproduct of cheese or casein, and they contain a higher percentage of pure protein. Additionally, it has a lower carbohydrate level and can be classified as lactose-free.

Not only does whey contain all the essential amino acids, but they are also easily digested.

Furthermore, according to a report published by Victoria University researchers, whey isolate is effective in increasing muscle and decreasing body fat than casein protein (1).

Muscle Milk contains isolate, concentrate, and hydrolysate forms of whey. However, because the supplements do not indicate the percentage of whey, it is impossible to figure out its effectiveness.

  • Maltodextrin

Maltodextrin is an FDA approved food additive obtained from corn, rice, potato, or wheat. Although it is normally used in small amounts, maltodextrin has a high Glycemic Index, and thus it spikes blood sugar. So, people with diabetes should be cautious when taking Muscle Milk.

  • Lactoferrin

Lactoferrin is a protein found in milk, bile, saliva, and tears. But, of the different types of milk, Colostrum is richest in lactoferrin. Moreover, this protein is ideal for iron transportation in the body and fighting infections (2). Furthermore, it has anti-inflammatory properties.

  • Milk Protein Isolate

Milk isolate is obtained from skim milk and is 90% protein. Plus, it contains 3% of lactose and amino acids.

  • Calcium Sodium Caseinate

Calcium caseinate is the scientific name for casein and is produced from skim milk too. And, it is the main ingredient in Muscle Milk.

Other ingredients include vitamins A, C, D, phosphorus, magnesium, potassium, calcium, and soluble fiber.

Muscle Milk nutrient facts

One scoop of Muscle Milk contains 160 calories, 16 grams of protein, 9 grams of carbohydrates, and 6 grams of fat

5. Where is It Manufactured?

Muscle Milk is manufactured in Benicia California at a 150,000 square foot manufacturing facility.

6. Who’s Muscle Milk For?

These protein powders and shakes are designed not only for athletes and gymnasts but also adults seeking to add size and weight.

Furthermore, with their protein content, these supplements double up as mid-morning snack or energy boosters, meaning they are ideal for people with demanding careers and jobs.

While anyone can consume these supplements, people with high blood sugar should be cautious. Maltodextrin has a high G.I (glycemic index) and can raise the blood sugar and trigger other health complications.

7. How Does The Supplements Work?

According to experts, the body builds muscle after exercise when the body is resting. Generally, taking a protein shake 15 to 20 minutes after an exercise will provide your body with all the essential amino acids and proteins to rebuild damage and form new muscles as well as promote tissue and bone repair (3).

Therefore, Muscle Milk supplements will probably help in rebuilding your muscles considering they contain 64% protein.

8. Does It Work?

None of the CytoSport claims are scientifically proven. However, research exists that supports the benefits of protein. Protein provides satiety, help in muscle building, and may also help with weight loss.

9. Benefits and Results

According to CytoSport, Muscle Milk in combination with exercise-training may contribute to healthy weight management, workout recovery, lean muscle gain, and sustained energy.

10. As Far as Taste Goes

Taste is Muscle Milk’s competitive factor. The protein shakes have a milkshake consistency and are available in banana, chocolate, coffee, strawberry and vanilla flavors.

11. How to Take the Supplements

Muscle Milk is available as ready-to-drink shakes. Plus, the powders are easy-to-mix with any form of beverage including smoothies.

12. Side Effects

Muscle Milk can interfere with your gut flora, living microorganism– good bacteria that maintain normal body function. Gut microbiota is your gateway to good health, and a comprised one is a ticket to different diseases.

Muscle Milk contains acesulfame potassium and sucralose–  artificial sweeteners that can impair your gut flora, affect metabolism processes, trigger weight gain, and insulin resistance.

Although the supplements are said to be milk free, the Milk protein isolate, casein, and whey protein can trigger allergic reactions in some people. High doses of whey protein can cause gas, diarrhea, bloating, and stomach cramping.

13. Product Warnings

Muscle Milk is reported to contain cadmium, lead, mercury, and arsenic. When consumed frequently, these metals can pose a serious health issue especially to pregnant women, people with diabetes and kidney problems.

Additionally, high levels of protein in the blood can also impair the function of kidney and cause kidney failure in people with kidney disease (4).

14. Lawsuits and Controversies

CytoSport has experienced their share of lawsuits and controversies and has had to part with millions to settle some of the lawsuits. In 2010, Consumer Reports, a consumer advocacy magazine in the United States, reported that two of CytoSport Supplements contained heavy metals exceeding the USP (United States Pharmacopeia) proposed levels.

According to the report, Muscle Milk Chocolate powder contains cadmium, lead, mercury, and arsenic at high levels. And, the Vanilla Cremé Powder has lead and arsenic.

In their response, CytoSport failed to address the claims directly. But, instead focused on their liquid shakes which they stated were within the USP proposed maximum levels.

Furthermore,  a class action was filed against CytoSport stating that the company gave misleading information on their ingredients. The plaintiffs explained that CytoSport claimed that the supplements contained L-glutamine when in reality they didn’t have much of the nutrient.

And, in 2013, CytoSport agreed to pay approximately $ 5.3 million to settle a class action for using the term ‘healthy.’ Initially, CytoSport had claimed that the protein shakes contain ‘healthy fats’ while they saturated fats instead.

15. What Are the Customers Saying?

“One thing about these protein shakes is that it isn’t just whey protein, but also contain a bunch of vitamins as well. Additionally, you have a year to use the whole thing before the expiration date.”


“The vanilla protein shake is my workout and meal replacement shake of choice. I love it as I can mix it with water and chocolate milk after my workout.”


“The changed formula is terrible.”


“I received the new and improved formula with a red top, and it doesn’t taste the same.”


16. Muscle Milk Alternatives

Other protein shakes you can opt for include:

  • 18shake
  • Ideal Protein
  • Isagenix

17. Final Verdict. Would I recommend Muscle Milk?


Muscle Milk is available in many variations, and you can get both online and on retail stores. But, it is not the best protein shake in the market. Additionally, the supplements have too many ingredients– some are not beneficial.

Even though they have little sugar, these protein shakes have added artificial sweeteners. Plus, the idea of having heavy metal in the powders is a bit alarming.

You can buy the supplements from the Official website and Amazon.
