Intro: What is it?

Myotein shake is a meal replacement claiming to offer time released high quality protein. There’s also mention it’s the top rated protein for over 5 years straight.

It’s currently offered in Chocolate, Vanilla, and a Chocolate Vanilla mixture. With exercise the brand is said to promote muscle growth and enhanced muscle mass.  3 days is the intended window of expected results. Are any of the claims actually true? How does this brand rank when compared to the best meal replacements? To figure out the truth about Myotein, read this full review.

Myotein Ingredients

Provided are the Vanilla ingredients:

Whey Protein Isolate Whey Protein Concentrate Micellar Casein Whey Protein Hydrolysate
L-Glutamine Colostrum Guar Gum Lactase
Sunflower Creamer Lecithin Sucralose Aminogen
Mucuna Pruriens Forslean 20-Hydroxyecdysterone Natural Flavoring
Artificial Flavoring

There are some controversial ingredients added:

Guar Gum: Common thickener often found in processed foods.  It’s also used as a laxative and it’s known to expand in the stomach, acting like a fiber. It’s recommended by sites like WebMD to also drink at least 8 ounces of water in order to prevent:

“choking or developing a blockage in the intestine”

It can also potentially lead to nausea, diarrhea, bloating, and gas.  In some people there can be an allergic reaction. This can lead to sores, flushing, itchiness, and many more issues.

Mucuna Pruriens: Tropical legume used for its many touted medical benefits. It can potentially lead to nausea, abdominal discomfort, hallucinations, confusion, delusions, and increased heart rate.  It’s also known to be highly irritable when touched.

20-Hydroxyecdysterone: Hormone that increases the growth of arthropods such as spiders, scorpions, shrimp, and butterflies. Studies have shown no clinical benefit to using this ingredient in humans.

Artificial Flavor: A synthetic ingredient which can be extracted from many different sources, including potential allergens such as soy, corn, dairy, and wheat. However, manufacturers are not obligated to mention where they sourced this ingredient from.

Macronutrients and Calories

Calories 118 Calories From Fat 10 Total Fat 1g, 2% Sodium 238mg, 10%
Potassium 1mg, 0% Total Carbohydrate 1G, 0% Dietary Fiber 0.5g, 2% Protein 26g, 52%


A small portion of calories are offered at 118, 10 of which are fat. The amount of fat per serving is:

10/118= 0.84 times 100= 8% fat per serving.

There’s a moderate amount of fat added. To put it in perspective, 20% fat and above could be considered high fat according to the FDA.


Only 0.5 grams of fiber are added which is incredibly low. To satisfy hunger you’d have to mostly rely on the protein added.

The fiber also comes from Guar Gum, which as described previously can potentially cause side effects and allergies. It’s not considered a quality protein source, and instead is a cheap thickener.


There’s 0 grams of sugar, however there is a sweetener added:

Sucralose: Artificial sweetener that provides no calories and isn’t properly digested by the body. It’s around 1,000 times sweeter than simple sucrose. Numerous studies have shown it to cause side effects in mice. The Department of Pharmacology at Duke University released a study which showed it lead to a:

reduction in beneficial fecal microflora”

Science Direct also released a study which also showed:

DNA damage in gastrointestinal organs”

The American Diabetes Association sponsored another study which showed it:

affects the glycemic and insulin responses”

All together , these studies have shown a negative impact on blood sugar, damage to the vital organs, and decreased healthy bacteria needed for the immune system to properly function. Even with it having no effect on adding to sugar, it’s been known to still have blood sugar raising effects.

The Quality of Myotein’s protein

Several varieties of protein are added to this mixture:

Whey Protein Isolate: A higher than average protein source which offers at least 90% protein source extracted from when cheese is made. It contains all the essential amino acid, and is considered a fast acting protein, useful for after a workout.

Whey Protein Concentrate: Slow digesting protein that also contains all the essential amino acids, though there’s less protein by weight than Isolate.

Micellar Casein: Dairy protein which creates a clot in the stomach, allowing for a long lasting source of amino acids.

Whey Protein Hydrolysate: The protein in this ingredient is broken down through heat or added enzymes. It absorbs much faster in the body than either concentrates or isolates, however this also produces a more bitter tasting protein.

L-Glutamine: Amino acid already made in the body. It’s the most commonly found amino acid. It’s often only required in those who are deficient such as vegans or vegetarians.  There’s’ no muscle building benefit to this ingredient unless one suffers from a deficiency, which is rare.

Colustrum: Milk taken from the breast of mammals late in their pregnancy cycle.  This provides more antibodies that babies need to fight off disease. Studies have shown there’s no benefit to taking this form of milk, since its beneficial parts aren’t properly digested by humans.

There doesn’t seem to be a unique benefit to Colustrum, and L-Glutamine is already made in sufficient amounts by the body, unless you’re vegetarian or vegan.

There’s a lot of protein added which some of it is good, however there’s also unnecessary additions. This raises the price of Myotein unnecessarily.

The Price and Quality of Myotein

One standard bottle containing 27 servings costs $59.95, these amounts to a daily price of:

$59.95/27= $2.20 times 2= $4.40 for 2 shakes a day.

There’s a potentially harmful sweetener, 2 unproven to be beneficial protein sources, and the use of artificial ingredients. Overall, the quality isn’t up to par with the very best meal replacements.

The Addition of Aminogen

The patented ingredient Aminogen is added in order to increase the absorption of protein. Aminogen is made up of 2 different bacteria strains:

Aspergillus Niger: Fungus that produces something called black mold. This type of mold can produce mycotoxins, which are known to cause toxicity in the kidneys.  Other possible side effects can include hearing loss, damage to the ear canal, and eardrum damage.

Aspergillus Oryzae: Mold often used in Japanese cooking to allow foods to ferment.  It allows proteins to be broken down to their amino acids and simple sugars.

The potential side effects from Aspergillus Niger are intense, and Pub Med has also studied this ingredient in a clinical setting, showing it had a:

potentially aggressive nature”

“significant morbidity and mortality”

In one specific case, a person suffered from pulmonary damage and extreme chest pain, this eventually leads to the person’s death.  This form of bacteria is considered to be extremely damaging.

Claims of being Top Rated

The company makes many bold claims that includes

“Top-Rated Protein 5 years running”

“#1 Trainer Recommended”

Now where on the official website or elsewhere are these claims backed up by evidence. They also mention that some people see results in 3 days, some as long as a week.

Once again they fail to provide any proof of these claims.

In researching this brand I didn’t see which organization gave them an award for being the best protein. It’s likely this isn’t true, since some of the added protein has not been proven to have any benefit.  It wouldn’t make sense for a group to rate this protein powder any higher than other formulas, since there’s costly and unnecessary ingredients added.

Also, when considering a high quality protein source, it’s also necessary to judge what the surrounding ingredients are. Artificial flavors knock down the value of this shake significantly, since it’s a cheap substitute which may cause allergies in some.


The company responsible for this brand is XPI Supplements, and they make other similar type supplements geared towards athletes. Their customer service representatives can be reached below:

Phone Number: (877) 999-7808

Address: 4778 North 300 West Ste 120

Provo, Utah 84604

There wasn’t any useful information found outside the company website. It appears they did have a Better Business Bureau listing, but it’s no longer available. This might be due to an increased amount of negative reviews.

The company does offer a money back guarantee, but it’s unknown how useful it is since no customers have commented on it.

Customer Opinions

Reviews for this brand are plentiful, with 49 critical reviews on Here are some of the most common reviews for Myotein:

“do not buy”

“unnecessary extras in this product”

“Won’t buy again”

“Decent product… but no better than anything else”

One of the most common complaints is that the chocolate had a bad taste, and that the vanilla was simply OK. People also took issue with the high price and addition of unnecessary ingredients, many of which have not been proven to have any benefit according to clinical studies.


The main points to consider about Myotein include the following:

  • Many of the ingredients are unnecessary: L-Glutamine, Colustrum, and Mucuna Pruriens have not been proven to have a benefit in most people. This increases the overall price of Myotein unnecessarily. Customers have also become aware of this fact due to the available research online. These ingredients are said to be beneficial for making the shake better-rounded, but it ends up being a pricy addition. Some of these ingredients are very costly, though they have not been proven to be beneficial in the average person.
  • There’s practically no vitamins and minerals: There’s added sodium which is common, and only 1mg or 0% of the daily requirements for potassium. Since there’s 0% of anything in the form of vitamin A, B, C, D, E, K, and several other minerals and nutrients, this means this shake is severely lacking in what a proper meal replacement should offer. This can make it more expensive to supplement with this product since you might end up feeling satiated, yet without the necessary nutrients the body needs to function properly. This further increase the overall cost of this shake.
  • Customers have rated the brand unfavorably due to price and taste: There’s major concern from people who claim all 3 flavors of this shake are hard to swallow. People have complained about the taste and mentioned its artificial tasting. There’s also been major concern about the quality of the ingredients. People mentioned they researched the brand and realized some of the additives are either potentially harmful, or not proven to have any benefit. So this further increases the cost unnecessarily, and prevents this shake from having a proper mix of ingredients.
  • It’s not an actual meal replacement: Though there’s a high amount of protein, this shake is severely lacking in nutrients and overall nutritional density. There’s virtually no fiber added, and much of the carbohydrates are lacking. The problem with it not being a meal replacement is that the 26 grams of protein make up 52% of the daily requirements, therefore 2 shakes gives off 104% of the daily value. Excess protein can lead to liver damage according to Web MD. Another issue is that protein is very satiating, so you might not have enough space in your stomach to eat more food. This can cause problems since you’re missing out on key nutrients when you supplement with Myotein.
  • Some of the ingredients may cause side effects: The artificial ingredients such as artificial flavors and sucralose have both been known to cause side effects. Some of the possible negative reactions can include damage to the internal organs, DNA damage, allergic reactions, reduced healthy gut bacteria, metabolism disorders, and even blood sugar issues. People who reviewed the ingredients also noticed how some of the additives are potentially damaging. Some of the possible problems are extremely negative, and the only reason they’re added is to provide a cheap substitute.

Myotein has many claims about its use, but customers have largely disagreed, may claim it’s overpriced and not tasty at all. There’s also concern over the unnecessary addition of ingredients which are unnecessary, this further increases the price. Though it is high in protein, some of the protein sources aren’t necessary or as useful as other meal replacements.
