Our verdict
MyProtein Impact Whey remains one of the best value whey proteins available — 21–22g of never-spiked protein, over 15 flavors, and a price that drops as low as $0.94 per serving at the largest size. It’s not the most feature-loaded whey on the market, but for pure protein-per-dollar, it’s hard to beat.
Pros
- Excellent value — as low as $0.94 per serving at the 200-serving size
- Informed Protein / Informed Choice certified — never spiked, independently verified
- 15+ flavors, from Chocolate Brownie to White Chocolate Peppermint
- 5g of BCAAs per serving
- Available in 4 size options (10, 40, 100, 200 servings) to try before committing
- Low fat, reasonably low carb for a concentrate-based whey
Cons
- Protein content varies by flavor — between 17g and 22g per serving, not a flat number
- Whey concentrate base means more lactose than an isolate-only product
- No added digestive enzymes, creatine, or other extras
- Slightly below the ~2.5g leucine threshold for maximally stimulating muscle protein synthesis in a single serving on some flavors
*Protein content varies by flavor, from 17g to 22g per serving. Unflavored version delivers 22g.
What Is MyProtein Impact Whey Protein?
Impact Whey is MyProtein’s flagship, best-known product — a whey protein concentrate that’s been a category staple since the brand launched, and remains one of the most purchased whey proteins globally on the strength of its price-to-protein ratio. Each serving is built around whey protein concentrate, MyProtein’s most economical protein source, without sacrificing the label transparency that’s become the brand’s calling card.
MyProtein backs this with Informed Protein and Informed Choice certification — third-party verification confirming the labeled protein content is accurate and free of the “amino spiking” tactics (adding cheap, non-protein nitrogen sources to inflate the protein number) that have periodically embarrassed parts of the industry.
Who Is It Best Suited For?
Impact Whey is the clear pick for anyone prioritizing cost per gram of protein without giving up on certification and label accuracy. If you go through protein powder quickly — multiple shakes a day, a large household, or just heavy daily use — the 200-serving size brings the cost down to under a dollar per serving, which is difficult to match from a certified brand.
It’s less suited to anyone who specifically wants a whey isolate for lower lactose/fat content, or who wants a protein with added extras like digestive enzymes or creatine baked in — Impact Whey is deliberately a simple, no-frills formula.
Cost per gram of protein is a priority without sacrificing third-party certification. You go through protein powder in high volume and want the per-serving cost to drop as you buy larger sizes. You want a wide flavor selection to avoid getting bored with the same shake every day.
Formula and Ingredients
The base formula is whey protein concentrate, sourced with sunflower lecithin, plus natural and artificial flavoring specific to each variant. Protein content genuinely varies by flavor — the unflavored version delivers 22g per 25g serving, while some flavored variants run closer to 17–21g depending on how much flavoring and sweetener displaces protein by weight. If hitting an exact daily protein target matters to you, check the specific flavor’s label rather than assuming a flat number across the range.
As a whey concentrate rather than isolate, Impact Whey retains slightly more fat and lactose than a filtered isolate product — generally not an issue for most people, but worth knowing if you’re notably lactose-sensitive.
Value for Money
This is where Impact Whey genuinely stands out. At the largest 200-serving size, the price works out to roughly $0.94 per serving — among the lowest cost-per-serving figures available from any third-party-certified whey brand. Even at the smaller 100-serving size, it’s around $1.00 per serving, still highly competitive. For anyone optimizing a supplement budget without wanting to gamble on an uncertified brand, this is one of the strongest value propositions in the whey category.
Frequently Asked Questions
Why does the protein content change between flavors?
Flavoring, sweeteners, and cocoa (in chocolate variants) all displace some protein by weight in the final formula. MyProtein’s nutritional info is based on the unflavored version; check your specific flavor’s label for its exact protein content.
Should I get Impact Whey or Impact Whey Isolate instead?
Impact Whey (concentrate) is cheaper and perfectly adequate for most people. Impact Whey Isolate costs more but delivers a flat 25g protein per serving with less fat and lactose — worth the upgrade if you’re lactose-sensitive or want a purer protein source.
What does “never spiked” actually mean?
Some manufacturers have historically added cheap nitrogen-containing compounds (not actual protein) to inflate the protein figure shown on the label. MyProtein’s Informed Protein certification independently verifies this isn’t happening with Impact Whey.
Final Verdict
MyProtein Impact Whey earns its reputation as one of the best value whey proteins on the market — genuinely certified, widely available in flavors that don’t get boring, and priced low enough at scale to make daily supplementation an easy budget decision. If cost-per-gram-of-protein is anywhere near the top of your priority list, this should be on your shortlist.
Certified, never-spiked whey concentrate at one of the best price-per-serving ratios in the category — 15+ flavors and a genuine budget standout.
