As a nutrition coach and athlete, I know all too well the importance of getting adequate daily protein. 

I also know how expensive it can get when you are supplementing with protein powder daily (and sometimes multiple times per day). 

That’s why I am always looking for products that combine quality and quantity so that I can get the best results possible without breaking the bank. 

MyProtein Impact Whey Isolate checks many positive boxes, with no drawbacks serious enough to deter me from wanting to rebuy their protein.

  • Impact Whey offers a rich flavor but might be too sweet for some consumers who prefer a more mild taste.

About MyProtein 

MyProtein was founded in 2004 and is currently based out of New York City, but operating out of 70 different countries. They pride themselves in marrying quality and quantity by producing everything in-house and cutting out third parties. 

They feature a long list of rewards and accolades from the UK that you can find on their About Us page.

I actually really like their motto, #YoureAlreadyReady.

Their marketing is not solely aimed towards athletes but tries to meet everyone where they’re currently at: 

“Fitness is a process. Whether you’re on day 1 or day 1000, your journey is sewn together by good intention. It doesn’t matter where you’re at or where you’re going. If you’re here, you’re already ready.”

As an aside, they also have a clothing line, which is incredibly reasonably priced and features many great options that I couldn’t resist buying while browsing the site.  

Alongside protein and clothing/workout accessories, MyProtein also sells vitamins, creatine, bars & snacks, meal replacements, weight gainers, and a line of vegan products. 

Is MyProtein Good? Overview of Impact Whey 

MyProtein is made using exclusively fast-digesting whey isolate and uses sunflower lecithin as an emulsifier. They use a variety of ingredients to flavor and sweeten the protein, including cocoa, natural and artificial flavors, sucralose, acesulfame-potassium, and salt.  

macronutrient breakdown of MyProtein protein

The macronutrient breakdown of MyProtein protein is: 

  • Protein: 20g  
  • Carbohydrates:  2g
  • Fat:  0g
  • Sugar: 2g

With 90 calories per scoop and 20g of protein, Impact Whey Isolate comes in at around 89% protein per scoop. 

This high protein percentage puts Impact Whey Isolate into the category of “great source of protein” as per our criteria (more on that below).

Impact Whey Isolate naturally contains 3.5g of glutamine and 4.5g of Branched Chain Amino Acids (BCAAs), both of which play crucial roles in workout recovery, making this a good post-workout option. 

A quick note: 

The bag that arrived to me (Mocha flavor) reads 20g of protein on the label.

When I look online though, the nutritional info provided for the unflavored option indicates it has 22g of protein per 90-calorie serving. 

This would make Impact Whey Isolate 97.7% protein per scoop if buying the unflavored option – the highest we’ve seen. 

This is even higher than Bulk Supplements, which I’ve also tried and tested.

Highlights: What I Liked About MyProtein Protein

Pros vs Cons of MyProtein Protein

High Protein Percentage Per Scoop

MyProtein Impact Whey Isolate offers between 89 and 97% protein per scoop, making it an excellent source of protein. 

Our criteria for assessing protein is the following:

  • Acceptable protein percentage: 65-74%
  • Good protein percentage: 75-84%
  • Excellent protein percentage: >85%

With 20g of protein per serving in the flavored options, this product is around 89% protein per scoop which puts it into the excellent category. 

If you go with the unflavored protein, you get an incredible 97% protein per serving, making this the absolute best value for high quality protein that we’ve come across. 

Good Taste and Variety of Flavors

Impact Whey Isolate is available in a variety of 8 different flavors (plus one unflavored option) and has a rich taste, even when just mixed with water. 

I personally tried the mocha flavor, and found that it had a really strong taste when mixed with water or milk, and it tasted fantastic blended into coffee.

While you can’t please everyone, browsing through the Amazon and MyProtein website reviews show that customers agree that Impact Whey Isolate tastes great (with the exception of Cookies and Cream, which has mixed reviews).

Mixes Really Easily, Even Without a Protein Shaker

Impact Whey Isolate mixed really easily into water, milk, coffee, oatmeal, and yogurt with no clumps and no chalky residue. 

I actually found myself gravitating to this product more than some of my other regular go-tos because I knew it would mix up easily and completely. 

Drawbacks: What I Didn’t Like About MyProtein Protein

Lots of Flavor Additives

The great taste is likely due in part to the high amount of sweeteners and flavors added to their formula, including Natural and Artificial Flavoring, Sucralose, and Acesulfame-Potassium.

While it’s not uncommon for companies to use both sucralose and acesulfame potassium in their formulas, they also use “natural and artificial flavoring”. 

According to the FDA, companies aren’t required to disclose what all goes into Natural and Artificial Flavoring, so there’s a possibility for higher amounts of chemical additives. 

They also don’t disclose how many mg of sweeteners are in their formulas, which some other companies have the courtesy of doing. 

Might Be Overly Sweet for Some Consumers

While the taste is enjoyable, it’s definitely on the very high end of the sweetness scale, and may be too sweet for some consumers. 

I usually mix my protein powders with less water than recommended in order to achieve a more rich taste. With my mocha flavored Impact Whey Isolate, I actually found myself diluting the protein with more water in order to achieve a more mild taste. 

Myprotein is Sold in a Zipper Sealed Bag Rather Than a Plastic Tub

MyProtein ships in bags with zipper seals, which can make for more precarious transport. 

This may be a pro or a con, depending on your lifestyle. Since it ships in a bag with a zipper seal, you’re at increased risk for accidentally puncturing the bag or the zipper opening in your gym bag, which could cause a mess and waste of protein. 

Alternatively, some customers that I have talked to prefer the bags because they are easy to pack into luggage for traveling and take up less space. 

Falls Into the More Expensive Range for Whey Protein

Impact Whey Isolate costs between $1.32 and $1.62 per serving, which on the surface is a good price for a high protein percentage isolate. When you adjust for the smaller scoop size, though, the price evens out. 

Other whey isolates that fall within this price range, like Transparent Labs Whey Isolate (93%) cost between $1.75 and $2.00 per serving. 

At first glance, MyProtein looks like a steal at as low as $1.30 per serving. There is, however, a little bit of nuance to be considered here. 

MyProtein Impact Whey Isolate only has 20g of protein per serving, where most other proteins have between 25 and 30g. 

In adjusting for the smaller scoop size, if you were to take 1.25 scoops per serving to get 25g of protein, then the cost is between $1.65 and $2.03 per serving. 

This levels the playing field and puts it on par (and in fact, slightly more expensive than) the Transparent Labs Isolate mentioned above which offers 28g of protein.

All of that being said, MyProtein frequently runs promotions on their website so it’s worth checking to see if you can save money on your order. 

MyProtein Protein Review: My Experience

MyProtein Protein user experience

Overall, I really enjoyed this protein and I liked having it around. It had a strong, rich flavor that shone through whether I just mixed it with water, or added it to coffee and oatmeal. (I tried the mocha flavor, specifically). 

I found the flavor to be very rich. This can be classified as either a pro or a con, depending on what you are looking for in your protein. 

While I liked the strong flavor, I did find that some days I just wasn’t in the mood for something that sweet and ended up reaching for other options in my cupboard. 

I have a dairy sensitivity, but I didn’t find any bloating, gassiness, or stomach discomfort with this protein. 

I took it with me to and from work for a week so that I could assess the quality of the bag it came in. I was definitely apprehensive of the bag packaging, and was worried that it would break open in my gym bag or get punctured and spill everywhere. 

After one week, the bag was showing some definite wear but everything stayed intact, and the zipper seal never leaked. I did, however, find myself being a lot more gentle with my bag and cautious when I had it in tow. 

Some wear and tear to the bag, but no holes or spillage.

I have listed the cost as a drawback here, because it does technically fall onto the expensive side of the whey isolate scale, coming in as high as $2.03 per 25g serving. That being said, over the few weeks that I spent reviewing this product, I checked their website frequently. 

They went from having a 20% off site wide sale, to a 40% off Super Bowl sale, to now offering a 35% discount site wide. Despite being a smaller scoop and only 20g of protein, if you can time it right and get their products on sale (which seems to be all the time) then that drawback is negated. 

On the whole, this product tasted good and mixed really easily. I am likely to repurchase and try some of the other flavors. 

How Does Impact Whey Isolate Stack Up Against Our Criteria For Whey Protein

At FeastGood, we have 8 different criteria for ranking whey protein powders.  Here’s how MyProtein Impact Whey Isolate Protein stacked up:

Nutrition Label Transparency 

Our rating: 4/5

All of the pertinent info (ingredients, macronutrients, calories, serving size) is clear and easy to read on the label and packaging

In some instances, we have seen brands completely disclose the exact doses of ingredients, for example the mg of artificial sweeteners used. 

We took MyProtein’s rating down to 4/5 for that reason; nothing is missing from the label, but they haven’t gone above and beyond in the same way that others like Transparent Labs has. 

Transparent Labs and MyProtein nutrition facts panel

On the left, you see the label for Transparent Labs which clearly labels the g of protein (31.11g), and the mg of cocoa, natural flavor, sodium chloride, and stevia. 

On the right is the MyProtein nutrition facts panel for the salted caramel flavor, which doesn’t have that same level of disclosure.

Fat Content Transparency 

Our rating: 4.5/5

MyProtein clearly labels the total grams of fat (0g), saturated fats (0g), and trans fats (0g) in their formula. 

Similar to the nutrition label transparency mentioned above, MyProtein doesn’t try to hide anything and clearly discloses everything that they are required to. 

Some brands do go the step further to indicate grams of mono/polyunsaturated fats, for which we would assign a full 5/5 for transparency. 

Effective Ingredients 

Our rating: 4/5

Impact Whey Isolate is made exclusively from whey isolate, a protein which is fast digesting and low in fats and sugars.  There are minimal added ingredients (like gums and fillers) but it does contain artificial sweeteners and flavors. 

MyProtein uses sunflower lecithin in place of soy, which means that this product is soy-free and has no gluten containing ingredients (except for the Cookies and Cream flavor which does contain both wheat and soy. 

Since this product uses only whey isolate and is very low in sugar, it’s possible that this option is acceptable for individuals with light to moderate lactose sensitivities.

Protein Percent of Calories

Our rating: 4.5/5

With 20-22g of protein per 90 calorie serving, Impact Whey Isolate offers 89-97% protein per scoop. This meets and exceeds our criteria for a great protein powder. 

Anything above 85% protein per scoop we consider to be a great option. The flavored proteins all meet that criteria, and if you go for the unflavored option you get an astounding 97%, the highest we’ve seen. 


Our rating: 4/5

Impact Whey Isolate has a strong, rich, and sweet flavor. It tastes great mixed into water, milk, oatmeal, yogurt, and smoothies but might be too sweet for some consumers. 

Taste is a subjective experience and it’s hard to find a flavor that will suit everybody’s taste. If you are looking for a strong, sweet flavored protein then this is a good option. 

I personally tried the mocha flavor and found it to be very sweet, but had a really true to taste flavor. 


Our rating: 5/5

Impact Whey Isolate is one of the best mixing proteins I’ve tried. It mixed easily into water and milk, and stirred into yogurt and oats with minimal effort. 

I typically used this product with a traditional protein shaker cup, but didn’t need a spring ball or whisk for it to completely dissolve. 

When a blender or frother was used, Impact Whey Isolate had a smooth and creamy texture. 

Texture (Thick or Thin)

Our rating: Thin

Impact Whey Isolate mixes up really thin, adding little to no texture to water or milk. 

The easy mixing makes this product an appealing, convenient post-workout or on-the-go option. 

This won’t be the ideal option for someone who wants a thick, filling shake. 


Our rating: 1/5

Being low calorie, lower in total protein, and made purely from isolate, this protein is fast digesting and won’t provide satiety past around 1-1.5 hours. 

The fast digesting protein makes it great for post-workout, or to add to meals or snacks to boost the protein content without adding lots of calories. 

On its own, this protein won’t promote satiety, and you would be better off choosing their Impact Whey or Meal Replacement. 

Who Is MyProtein Impact Whey Isolate For? 

  • Someone looking for a low calorie protein shake that mixes easily into anything
  • Someone who wants a product with a strong taste even when mixed with just water
  • Individuals who are looking for a post-workout protein

Who Shouldn’t Take MyProtein Whey?

  • People with dairy sensitivities, and individuals with gluten or corn allergies should also avoid the Cookies and Cream flavor. 
  • Anyone looking for a satiating protein

MyProtein Customer Reviews

MyProtein Impact Whey protein powder

On the MyProtein website, Impact Whey Isolate has a 4.47/5 star rating. 

Most of the negative reviews are actually recent ones, with consumers indicating that the product seems different from bags they’ve purchased previously, very specifically with the vanilla flavor. 

One review reads, 

“Something’s changed DO NOT BUY. This vanilla protein isolate that I have been buying for the past 4 months has changed. It now tastes and smells like chemicals….”

A second review, from a different verified purchaser posted just one day prior reads: 

“The vanilla isolate has always been my favorite protein. It tasted great and mixed well with milk or yogurt. But the most recent bag I got was awful! It had a chemical smell and taste. The color and consistency were different. It even burned my tongue a bit”

I can’t see any indication that they’ve changed their formula or ingredients, which leads me to wonder if we are simply dealing with a mis-flavored batch (e.g. the flavoring got missed, or the wrong dosage of sweetener was added). 

MyProtein did reply to a customer’s email inquiries saying that they are looking into it, but I haven’t seen any definitive resolution.  

Amazon reviews are very similar to those on the MyProtein website, with a 4.5/5 star rating based on over 9000 reviews. 

Mimicking the reviews from the MyProtein website, the most recent review on Amazon reads: 

“I’m stuck with the vanilla flavor until I can finish it. Honestly one of the most unenjoyable things I’ve ever had to force myself to drink. Disgusting”.

So clearly, something is going on with some of the most recent batches of Impact Whey Isolate. 

That being said, the rest of the feedback is positive. There isn’t much more new information to be gained. Some people love the taste, others hate it. Some people say it mixes great, others say they hate how it mixes.  Pretty standard when looking at hundreds of reviews. 

MyProtein Promotions & Discounts

One of my favorite things about MyProtein was the overwhelming amount of discounts I found on the website. 

At the time this article is being written, the website is offering up to 50% off some products, as well as 20% off site wide using the code TAKE20. Try it to see if it works, but likely by the time you’re reading this the sale will be over.

(It was this promotion that sucked me into ordering extra clothes after my protein arrived). 

They also have a promotion where you can earn $20 by referring friends. If you refer a friend and they spend at least $50, they save 40% off their order and you earn $20 in credit. 

There’s also a link to save an extra 5% off your first order, no link necessary. 

But wait, there’s more!

There’s a current donation incentive called MyProtein Supports Black History Month. If you donate to one of the non-profits on the page, you earn an extra 5% off your order. 

Military Personnel and Veterans get 45% off site-wide with free shipping. 

MyProtein has an app (on both iOS and Android) where they will send some exclusive offers and discounts. 

You can find a complete list of all active MyProtein voucher codes here.

Where To Buy MyProtein? 

Based on the number of discounts outlined above, the best place to buy MyProtein is direct from the MyProtein website. It is most likely that you will find the best price there. 

That being said, if you want more accurate and reliable shipping times, then you can also buy MyProtein online from

Other Types of MyProtein Protein Powder

MyProtein Clear Whey Isolate

MyProtein Clear Whey Isolate is the protein powder for people who don’t like the traditional milkshake-like flavors. 

Clear Whey Isolate mixes up much lighter and thinner, more like a juice than a milky shake. 

Furthermore, they stray away from typical protein flavors and offer more juice-like flavors such as lemonade, green apple, blood orange, and two MIKE AND IKE® flavors – Caribbean Punch and Sour Watermelon!

Clear Whey Isolate offers 20g of protein, with 0g of fat and less than 1g of carbs. With 80 calories per serving, this product is advertised as 100% protein per scoop. 

Clear Whey Isolate is more expensive than the Impact Whey Isolate, retailing on amazon for around $1.57 per scoop and up to $2.00 per serving on the MyProtein website.  

Being made of purely fast digesting whey isolate, this is a good post-workout option, similar to Impact Whey Isolate. Having so few calories, this option isn’t for people looking for something to keep them full. 

If you want something with more satiety, try MyProtein Impact Protein Blend. 

Impact Whey Protein

Impact Whey uses whey concentrate as opposed to whey isolate. Whey concentrate is naturally higher in carbs and fats than an isolate, and digests more slowly. 

This results in a protein that will help keep you fuller a little bit longer, and is slightly higher in calories (100 per serving). The use of whey concentrate drops the overall protein percentage to 76% from the 87%+ found in Impact Whey Isolate.

Impact Whey Protein aims to find the sweet spot between quality and quantity. It offers up 19g of protein for between $0.95 and $1.00 per serving (if you buy the 5 to 11lb bags which retail for $99.99 and $189.99 respectively). 

On Amazon, you can also buy 40 serving bags for anywhere from $33 to $45, depending on the flavor. 

If you want the benefits of a third party tested, high quality product but don’t want the high price tag that often accompanies it, MyProtein’s Impact Whey is a good option (and it actually has slightly higher reviews than the Whey Isolate). 

It is available in 15 different flavors, including chocolate mint, marshmallow cereal, and chocolate brownie as well as an unflavored option.

Impact Vegan Diet

Impact Vegan Diet

MyProtein offers a really unique formula for people whose goal is weight management. 

Impact Vegan Diet blend uses pea protein isolate and brown rice protein, and has added ingredients including L-Carnitine, digestive enzymes, Green Tea Leaf extract, and probiotics to support digestive health, glucose metabolism, and fat metabolism. 

This product has 20g of protein per serving, and 110 calories (73% protein per scoop). This looks low compared to the other whey proteins discussed today, but this is actually a decently high percentage for a vegan protein. 

Furthermore, this product has 8g of carbohydrates, 7 of which come from fibre. The high fibre content will contribute to prolonged satiety, which can support this product being used in a calorie controlled diet. 

It’s available in chocolate or vanilla flavors, sweetened with stevia, for $1.62 per scoop.
