Applied Nutrition Critical Whey and Myprotein Impact Whey are two of the most popular whey powders in the UK, and they are closer on price than most people expect.

Is Applied Nutrition cheaper than Myprotein?
Not quite, but the gap is small. Myprotein Impact Whey costs £1.18 per 25g of protein in the 2.7kg bag at £91.49, checked 22 September 2026. Applied Nutrition Critical Whey costs £1.20 per 25g of protein in the 2kg tub at £68.95 on appliednutrition.uk, checked 23 September 2026.

Which has more protein per scoop?
Per 100g they are level, and per scoop Applied Nutrition gives a little more. Applied Nutrition Critical Whey contains about 72g of protein per 100g, which is 24g in a 33g scoop, after a September 2025 reformulation from 21g in a 30g scoop. Myprotein Impact Whey contains 72g of protein per 100g in Vanilla, which is 22g in a 30g scoop. The bigger Critical Whey scoop is why it shows more protein per serving, not a richer powder.
Many UK listings still show the old Critical Whey panel of 21g per 30g scoop. If a listing says 30g, it is describing the previous formula. Our Applied Nutrition Critical Whey review covers the change in detail.
Is Applied Nutrition or Myprotein Informed Sport tested?
Applied Nutrition has three Informed Sport certified Critical Whey flavours: Chocolate Milkshake, Strawberry Milkshake and Vanilla Ice Cream. The rest of the Critical Whey range is not certified. We have not verified Informed Sport status for Myprotein Impact Whey, so if you compete in a drug-tested sport, check the batch certificate for whichever product you buy. On what we have confirmed, one of the three certified Critical Whey flavours is the safe choice.

Should you buy Applied Nutrition or Myprotein?
On price it is close to a draw, so decide on what else matters to you. Buy Myprotein Impact Whey if you want the widest choice of flavours and bag sizes, or you are buying in a Myprotein sale.
