We keep Myprotein Impact Whey Protein Powder | Chocolate Smooth on our diet & nutrition shelf alongside 38 others, and rank it on rating, review volume and live price rather than on the brand. The manufacturer puts it this way: Contributes to the growth and maintenance of muscle mass. Ideal for anyone looking to increase daily protein intake. That is the maker talking, not us, so read it as a claim rather than a finding. It holds 4.3 out of 5 on Amazon from 3,725 ratings. Where that leaves it next to the rest of the shelf is set out below.
Across the 39 rated diet & nutrition products we track, the middle of the pack sits at 4.4 out of 5. This one scores 4.3. That's inside the bottom quarter of the shelf. It isn't a warning, but better-rated options do sit alongside it at similar money, so you would want a specific reason to pick this one.
Behind that score sit 3,725 ratings, against a shelf median of 2,416. That's a solid enough base to read the score, though not enough to settle it.
Price-wise it falls in the top third of a shelf that stretches £4.99 to £97.98, with £12.00 in the middle. Paying above the middle of the shelf needs a reason the star rating does not supply, because on ratings alone the extra money is not buying an advantage here.
