About The Brand

Myprotein was founded in 2004 with the mission to fuel people all over the world. Based out of New York City, it has since expanded to serve over 70 countries through a dedicated team of knowledgeable staff, athletes, and brand ambassadors. 

Myprotein offers a large selection of products (including protein powders, protein shakes, protein snacks, and vitamin supplements) that cater to a wide range of nutritional needs. In addition, Myprotein offers products that are vegetarian- and vegan-friendly, as well as gluten-free and dairy-free.  

Everything is produced in-house, cutting down on third-party costs, and Myprotein takes great care in minimizing its environmental impact. For example, its “zero landfill policy” ensures all its waste can be recycled or used in refuge-derived fuel. 

Products are tested in-house using Near-Infrared scanning and X-Ray machines to ensure they meet the highest quality standards. Additionally, Myprotein works with independent partners who test and approve its products, including its Impact Whey Protein. They are also certified by Informed Choice for purity and banned substances.

The Myprotein Impact Whey Protein powder provides 21 grams of protein content, including 4.5 grams of branched-chain amino acids, or BCAA, per serving. This Impact Whey Protein review will break down the ins and outs of the protein powder to help you decide if it’s right for your goals.

What Is Myprotein Impact Whey Protein?

Myprotein Impact Whey Protein is a whey concentrate protein powder that provides 21 grams of protein per serving, including 3.6 grams of glutamine and all of the essential amino acids. On top of that, it also provides 4.5 grams of BCAA, which can help to repair and gain muscle mass. Glutamine combats sugar cravings, promotes muscle growth while preventing muscle wasting, improves gastrointestinal health, and boosts metabolism.

And even with the substantial protein content, the whey protein supplement is lower in carbs and fat than many other brands. There is just one gram of fat and three grams of carbs per serving. As a result, there are just 100 calories per serving, meaning you can boost your protein consumption without dramatically increasing your daily calorie intake. 

Myprotein also sells Impact Whey Isolate protein powder, so it’s important to verify your protein preferences before purchasing.

Impact Whey Protein Ingredients

You can also stack the Impact Whey with other Myprotein products. Myprotein offers a variety of protein powders, shakes, and snacks as vitamins and pre-workout products. Whether your goal is to gain muscle, lose weight, or maximize your overall health, Myprotein Impact Whey might be a great choice for you.

Myprotein’s Impact Whey Protein concentrate is one of the best value protein powders available today. The cost of the supplement reflects limited carbohydrate and fat content, meaning you’re mostly paying for the whey protein concentrate.

Whey Protein Concentrate

Whey concentrate is a commonly used form of protein in many different supplements. It typically has a higher percentage of lactose than whey isolate, but it is still relatively low in fat and carbs. In addition, whey concentrate is rich in BCAAs and the amino acid glutamine, which can be an excellent choice for individuals who want to gain muscle mass.

Emulsifier (Soy Lecithin)

Lecithin is an additive made from a variety of sources, one of those being soy. Like in Myprotein’s Impact Whey, It is typically used as an emulsifier or lubricant. It can be found in many products, including ice cream, infant formula, bread, convenience food, and dietary supplements.


Myprotein uses artificial and natural flavoring. Myprotein flavour options for its whey concentrate protein powder include chocolate smooth, chocolate mint, chocolate brownie, vanilla, chocolate stevia, vanilla stevia, mocha, birthday cake, unflavored, and more. With so many to choose from, it’s can be hard to choose the best impact whey protein flavour.

Note that there are sulfites in some of the flavors and these are allergenic[1] for many people. They may cause headaches, diarrhea, stomach pain or hives in sensitive individuals.


Myprotein lists two types of colouring in their whey concentrate: caramel and vegetable juices. However, not all flavors have added colouring.

Sweetener (Sucralose)

Many artificial sweeteners mimic the taste of sugar but lack calories. However, sucralose is unique because it’s an artificial sweetener made from sugar. After the sugar undergoes a chemical process, the resulting product (sucralose) is exponentially sweeter and essentially free of calories. 

However, a recent 2022 study showed that sucralose had an adverse effect[2] on the gut microbiome, causing blood sugar spikes and dysregulation. It has been reported to cause headaches, gastrointestinal upsets, epilepsy, and even weight gain in some people.

Other Ingredients

Different flavors have varying ingredients. While not all products are the same, other ingredients include: 

  • Modified food starch
  • Gum Arabic
  • Maltodextrin
  • Acesulfame K
  • Salt
  • Cocoa powder

Health Benefits Of Impact Whey Protein

Adding a protein supplement to your fitness routine can be highly beneficial as you work toward your muscle gain or weight loss goals. However, Impact Whey Protein can offer day-to-day health benefits as well. 

Research has shown that consuming 25 grams of whey protein post-workout tends to improve net protein balance[3] in the body, and improved protein balance can help enhance exercise recovery. For example, a large review study found that daily doses of whey protein supplementation may reduce C-reactive protein[4], a sensitive marker of inflammation in the body. 

Other research shows that whey protein supplementation[5] can have beneficial effects on body weight, total fat mass, and risk of cardiovascular disease in overweight or obese individuals. In addition, a 2015 study concluded that consuming whey protein in your dietary regimen could ultimately reduce your overall caloric intake[6] throughout the day. 

Potential Side Effects

It’s important to remember that your protein shake should not regularly act as a meal replacement but instead as an efficient way to get more protein in your diet. Of course, it’s best to meet your nutrition needs through whole foods, but it would be unrealistic to think everyone can get enough protein that way. 

Sometimes life gets busy, or your body’s demands increase. Regardless, relying on protein supplements is considered safe for the average adult when taken appropriately. However, monitor your body for any potential side effects. 

Potential side effects include but are not limited to

  • Bloating
  • Increased bowel movements
  • Nausea
  • Reduced appetite
  • Tiredness
  • Headache

The controversial ingredient, maltodextrin, is an ultra-processed food starch that may cause gut dysbiosis[7] and gastrointestinal upset in some people as well as affect the absorption of key nutrients such as BCAAs. This ingredient is present in the formula.

The controversial ingredient Acesulfame K is processed using methylene chloride, which may cause headaches, visual impairment, and liver complications. This sweetening ingredient is also in the formula.

If you experience unwanted side effects from taking Myprotein Impact Whey concentrate protein powder, contact your doctor or registered dietitian nutritionist. 


Myprotein recommends taking one scoop (25 grams) of the Impact Whey Protein powder, mixed with water or milk, approximately 30 to 60 minutes after your workout. However, you can mix up your protein shake at any time of the day that works best for you or as directed by your doctor. Some people take it as a pre-workout supplement. 

While supplemental protein content can help meet your estimated nutrition needs, it should not take the place of whole foods in your well-balanced diet. Instead, rely on your protein supplement to fill in the gaps as appropriate. 

Impact Whey Protein Review: What Do Real Users Say?

The Myprotein website showcases over 24,000 reviews for the Impact Whey Protein supplement and more than 17,000 of those reviews reflect five stars. Here are a few reviews found on the product’s page:

I’ve been using Myprotein for a long time and I can admit a long time ago in the past their whey protein was not very good and didn’t mix well. Hats off to them now as they have continuously improved their recipes and the taste is great and the powder mixes very well. Always looking to improve and make their products better for their customer


Tastes great and so effective for when on the go juggling early morning sessions and long hours.  Since taking it I’m definitely seeing improvements which Is keeping the motivation up


Coconut flavoured impact whey is without a doubt the best tasting whey I have had from myprotein. I’ve been buying and drinking whey protein shakes since the age of 16, and now I’m 40. Over the years, I’ve tried almost all whey products on the market, and this is maybe the best tasting I’ve ever tried, and that’s including all brands and flavours. If you haven’t already, get it, and if you’re skeptical just buy the smallest size available for a taste test.


Final Thought

If you’re shopping for a high-quality protein powder and you just want a no-brainer choice, Myprotein may have the answer for you. The Myprotein Impact Whey Protein concentrate can be a great way to help you meet your protein needs. With 21 grams of protein per serving, this post-workout shake can help you meet your extra protein needs. 

Myprotein’s Impact Whey Protein powder is certified by Informed Choice meaning it has been tested by a third-party lab for banned substances and is safe for professional athletes.

Myprotein’s Impact Whey Protein powder comes in over 40 different flavour options, including salted caramel, chocolate smooth, chocolate mint, strawberry cream, birthday cake, and vanilla. While it may not be the cheapest option or have the highest protein content, it is a great value-for-money product.

Myprotein Impact Whey Isolate protein is also available on the website, so be sure to shop carefully if you prefer the whey concentrate. And, as always, this Myprotein review does not take the place of medical advice. If you have questions about your protein needs, reach out to your registered dietitian nutritionist and always get clearance from your doctor before starting a new supplement.
