Myprotein Impact Whey is a whey protein concentrate powder from the UK sports nutrition brand Myprotein. One 25 g (0.88 oz) scoop delivers 19 to 22 g of protein for about 100 calories. The powder comes in 40 to 60 flavors. A 2.2 lb (1 kg) bag costs about $27 and holds 40 servings.
The product is a concentrate, not an isolate. The formula holds whey protein, soy lecithin and sweeteners. Reviewers praise the low price and easy digestion. Others dislike the sweet taste and mild bloating. Scores range from 2 to 4.5 out of 5. Healthy adults tolerate it well, though milk and soy allergens apply. Pricing stays low.
Value is the real story here. The cost per gram of protein is low, and the nutrition numbers are solid. The sections below cover ingredients, benefits, taste, side effects and pricing. Each one gives buyers real numbers to compare. The goal is a clear verdict on whether the powder earns a spot in the cupboard.
What Is Myprotein Impact Whey?
Myprotein Impact Whey is a whey protein concentrate powder sold by the UK sports nutrition brand Myprotein. The company launched in 2004 and now operates in about 70 countries. Impact Whey is its best-selling product, built for fast-absorbing protein after workouts and for daily intake. Over 80% of the powder is protein. Reviewers call it an easy start.
The powder contains over 80% protein by weight. Each scoop supplies the full essential amino acid profile. Myprotein produces supplements in-house, which keeps costs low. And that’s the core of the brand’s pitch.
Is Impact Whey a Concentrate or an Isolate?
No. Impact Whey is a whey protein concentrate, and Myprotein sells a separate product called Impact Whey Isolate. Proteinguide confirms the sole protein source is whey protein concentrate. The isolate line uses filtration that removes most lactose, fat and ash. Its protein share runs higher. The isolate costs more but carries far less lactose per serving.
The two products differ in purity, calories and lactose. Why does that matter? Lactose-sensitive buyers tolerate the isolate far better. Here’s the side-by-side view:
Impact Whey vs Impact Whey Isolate:
| Factor | Impact Whey | Impact Whey Isolate |
|---|---|---|
| Protein source | Concentrate | Isolate |
| Protein per scoop | 19 to 22 g | 20 to 25 g |
| Protein share | Over 80% | 89 to 97% |
| Calories per scoop | 100 to 104 | 90 to 93 |
| Lactose | Higher | Under 1 g |
Bottom line: the isolate wins on purity and lactose. The concentrate wins on price.
What Is in Myprotein Impact Whey?
Impact Whey contains whey protein concentrate, soy lecithin, flavoring and the sweeteners acesulfame K and sucralose. Proteinguide lists whey concentrate as the sole protein source. Wild Bloom Families reports no fillers or binders in the formula. The sweeteners appear in the flavored versions of the powder. Flavorings differ across the range. Flavors vary.
Each serving delivers all nine essential amino acids. Proteinguide reports 4.5 g of BCAAs and 3.6 g of glutamine per scoop. Wild Bloom Families lists 5 g of BCAAs. In fact, labels vary slightly by flavor.
The powder contains milk and soy. Soy comes from the lecithin emulsifier. To be clear, anyone with either allergy needs to skip it.
What Are the Nutrition Facts?
One 25 g (0.88 oz) scoop contains about 100 calories, 19 g of protein and under 2 g of fat. Eat This Much lists 100 calories, while Proteinguide lists 104. Sources report 19 to 22 g of protein. Carbs run 1 to 3 g. The spread comes from flavor and batch differences. The numbers suit calorie-aware diets, and the carbs stay very low. Protein leads the macros.
Nutrition per 25 g Scoop:
| Nutrient | Amount |
|---|---|
| Calories | 100 to 104 |
| Protein | 19 to 22 g |
| Carbs | 1 to 3 g |
| Fat | 1.7 to 2 g |
| Sodium | 35 mg |
| Calcium | 150 mg |
Protein supplies about 78% of the calories, per Eat This Much. The scoop also covers 15% of the daily calcium value. Not bad for a budget powder, right? The macros fit a calorie-conscious diet.
How Does Myprotein Impact Whey Work?
Impact Whey supplies fast-absorbing whey protein that the body breaks into amino acids for muscle repair. Whey digests quickly, so amino acids reach the muscles within a short window. Proteinguide credits this speed for the powder’s fit around workouts. The body then uses the amino acids right away. Speed explains why whey is popular after training.
Leucine, one of the BCAAs, triggers muscle protein synthesis. Impact Whey carries about 4.5 to 5 g of BCAAs per scoop. Glutamine adds support for recovery. So, what does that mean in practice? Faster repair after hard sessions.
When Should You Take Impact Whey?
The Proteinguide reviewer took a scoop 30 to 60 minutes after training as a recovery drink. The reviewer also used a scoop 30 minutes before some workouts. Either timing works, and the powder fits any time of day. Proteinguide adds that a combination of both options is fine too. The label also suggests a milk-based shake before bed. Timing is flexible.
How to Prepare a Serving:
- Add 6 to 8 ounces (180 to 240 ml) of water or milk to a shaker.
- Add one scoop of powder.
- Shake for several seconds until smooth.
- Drink after training or at any other time of day.
Here’s the part most people miss: milk slows absorption. That makes a milk-based shake a smart pre-bed option.
What Are the Benefits of Myprotein Impact Whey?
Impact Whey delivers muscle recovery support, high protein intake and low calories per serving at a budget price. Suppie scores the product 91 out of 100, with efficacy at 92 and cleanliness at 90. The ratings rest on whey research, including randomized controlled trials. Safety rates high for healthy adults. Convenience adds to the overall appeal here.
Reviewers also value the convenience. A single scoop adds 19 to 22 g of protein to a day in seconds. Is it the only way to hit protein targets? No, but it’s one of the cheapest.
Main Benefits:
- 19 to 22 g of protein per scoop
- Fast absorption for post-workout use
- Around 100 calories per serving
- 40 to 60 flavors
- Low price per gram of protein
Does Impact Whey Build Muscle?
Yes. Impact Whey supplies the protein and leucine that muscle growth requires when paired with resistance training. Suppie rates the muscle growth evidence as very strong. Curex cites meta-analyses showing whey plus lifting increases lean mass and reduces fat mass. Recovery evidence scores very strong as well. The evidence is consistent across trials.
Total daily intake matters most. Curex cites a target of 1.2 to 2.0 g per kilogram (0.54 to 0.91 g per pound) of body weight. One scoop covers only a small share of that. The shake supports the plan. It doesn’t replace food.
Does Impact Whey Help With Weight Loss?
Yes. Impact Whey helps weight loss by adding protein at roughly 100 calories per scoop. Protein is the most satiating macronutrient, and adequate intake preserves lean mass in a calorie deficit. Suppie rates the weight management evidence as strong. Low calories per serving keep the energy budget intact. Protein also supports diet adherence. Fullness lasts.
Satiety is the weak spot. FeastGood scored the isolate version 1 out of 5 for satiety. In plain English: treat the shake as a protein supplement, not a meal.
What Do Myprotein Impact Whey Reviews Say?
Myprotein Impact Whey reviews range from 2 to 4.5 out of 5 depending on the reviewer and flavor. Proteinguide gave 2 out of 5 stars. FindingFitness gave 4.5 out of 5. Suppie scored 91 out of 100. Taste and digestion drive most of the gap between these verdicts. Value earns praise in nearly every review. Sensitive users report occasional bloating, too.
Review Scores:
| Source | Score | Main Point |
|---|---|---|
| Proteinguide | 2 out of 5 | Sweet taste, bitter aftertaste, bloating |
| FindingFitness | 4.5 out of 5 | Good value, safe, easy to digest |
| Suppie | 91 out of 100 | Strong efficacy, low risk |
| FeastGood (Isolate) | 4.0 out of 5 | High protein share, easy mixing |
Scores split mainly on taste and tolerance. But value earns praise across every source. Why the split? Personal taste and gut sensitivity differ.
What Do Reviewers Like About Impact Whey?
Reviewers praise the low price, the wide flavor range and the easy digestion of the powder. FindingFitness rated value 5 out of 5 and digestion 5 out of 5. The reviewer felt no bloated feeling when mixing with milk. Sundried highlights the 60 flavor options on offer. Digestion earned a perfect score. Buyers repeat the point that the price reads as fair.
Safety also scores well. A 2016 FindingFitness review cited Labdoor testing, where the product passed heavy metals assays. Arsenic, lead and cadmium all measured below 1.0 ppm. The good news? Contaminants weren’t a concern.
What Are the Common Complaints About Impact Whey?
The top complaints are an overly sweet taste, occasional bloating and fiddly packaging. Proteinguide described a bitter aftertaste and some belly bloating. A Google review summary adds that the pouch zipper can fail over time. The same summary says the scoop can sink into the powder. Packaging problems are minor but common. Taste complaints dominate.
Mixability draws mixed reports. FindingFitness rated it 3 out of 5 after finding occasional clumps in a blender. Proteinguide saw the powder blend within seconds in a shaker. Is it a dealbreaker? For most buyers, no.
How Does Myprotein Impact Whey Taste?
Impact Whey tastes sweet, and opinions vary widely by flavor. Myprotein offers 40 to 60 flavors. Sundried tested banoffee, rocky road, speculoos, marzipan, cinnamon danish and stracciatella. Reviewers call most of them pleasant but sweet. Flavor choice is the biggest variable in the whole experience. Sweetness is the common thread across most reviews.
Marzipan was Sundried’s favorite. The reviewer said it smells and tastes like real marzipan. Rocky road was too sweet for daily use. So, which flavor wins? Marzipan, by that account.
Vanilla fared worst. Proteinguide called it artificial, very sweet and bitter in the aftertaste. FindingFitness liked cookies and cream, rating it 4 out of 5. Here is the kicker: the same brand earns opposite verdicts.
How Well Does Impact Whey Mix?
Impact Whey mixes quickly in a shaker and blends smoothly in most reviews. Proteinguide reported a nice consistency with no chunks after a few seconds. FindingFitness saw clumps now and then in a blender. Shaker cups give the most reliable result, so a shaker is the safer tool for daily use. Mixing is rarely a real problem for most daily shaker buyers.
Milk makes the shake taste like ice cream, according to FindingFitness. Water keeps calories lower. Both liquids work, and the choice comes down to taste versus calories.
What Are the Side Effects of Myprotein Impact Whey?
Impact Whey causes mild digestive effects such as bloating or gas in some users, mainly those sensitive to lactose. Suppie rates the overall risk as low. Concentrate holds more lactose than isolate. The Proteinguide reviewer felt belly bloating and some sluggishness after use. Symptoms stay mild and short-lived for most healthy adults who tolerate dairy.
Possible Side Effects:
- Bloating or gas
- Digestive discomfort
- Allergic reaction in milk-sensitive people
- Nausea when taken on an empty stomach
Suppie flags sucralose as a medium-risk ingredient. All other inactive ingredients rate low risk. What’s more, no major contaminants appear in Suppie’s report.
Who Should Avoid Impact Whey?
People with a milk or soy allergy need to avoid Impact Whey because the powder contains both allergens. Suppie also advises caution for children under 4. Those with kidney disease or diabetes need to consult a doctor first. Suppie notes that allergen cross-contamination is possible during manufacturing. Pregnant women usually tolerate it in moderation.
Excess intake carries risk. Suppie warns that intake above 2 g per kilogram (0.9 g per pound) may strain stressed kidneys. One to two servings daily is the safe range. Fair enough?
How Much Does Myprotein Impact Whey Cost?
Impact Whey costs about $26.99 for a 2.2 lb (1 kg) bag with 40 servings. Proteinguide calculates 3.55 cents per gram of protein. A 2016 review listed $25.69 for 2.2 lbs and $52.99 for the 5.5 lb (2.5 kg) bag. Myprotein often runs promo codes that cut the price further. Larger bags lower the cost per serving for heavy users, and they last for months.
Price Snapshot:
| Size | Price | Source |
|---|---|---|
| 2.2 lb (1 kg) | $26.99 | Proteinguide |
| 2.2 lb (1 kg) | $25.69 | FindingFitness, 2016 |
| 5.5 lb (2.5 kg) | $52.99 | FindingFitness, 2016 |
Prices shift with promotions. For that reason, the current Myprotein listing is the final check before buying.
Is Impact Whey Worth the Price?
Yes. Impact Whey delivers strong value for buyers who prioritize price over taste and purity. Proteinguide’s 3.55 cents per gram of protein is low. FeastGood found the isolate costs $1.32 per serving against a $1.34 whey average. The concentrate sits below that level, so the savings are real. Savings add up over a year of use. Savings add up over a year.
The concentrate is cheaper still than the isolate. But Proteinguide cautions that the low price matches the lower protein quality. Worth it? Yes, if the budget leads the decision.
