Optimum Nutrition Whey Protein Powder Vanilla Flavour, 22g Protein is one of 45 protein powder products on our shelf, compared on what buyers rated it, how many of them there were, and what it costs today. Here is how the maker describes it: Contains 100% whey protein concentrate, a high‑quality source to help meet daily training and nutrition goals. Each serving provides 22 g of protein that contributes to the growth and maintenance of muscle mass – ideal when combined with strength training. That is the maker talking, not us, so read it as a claim rather than a finding. On Amazon it sits at 4.1 out of 5 across 74 ratings. How that compares with the rest of the shelf is below.
Taken from the wording on the listing itself and the price we track, not from a brand claim about value. How we rank →
Across the 45 rated protein powder products we track, the middle of the pack sits at 4.4 out of 5. This one scores 4.1. Bottom quarter of the shelf. Not a red flag by itself, but similar money buys a better-rated option here, so the case for this one has to come from somewhere else.
74 people rated it, where the shelf median is 474. That's a thin base for this shelf. A score from a small number of buyers can move a long way on a handful of new reviews, so treat it as a first impression rather than a settled verdict.
On money, this sits in the bottom third of a shelf running from £14.66 to £170, with the midpoint around £40.00. Buying at the cheap end is fine as long as the rating stands up. Here it does not quite, so check what has been cut before assuming the saving is free.
