Optimum Nutrition Gold Standard 100% Whey Protein Powder,2.27 kg is one of 39 diet & nutrition 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: Designed for goal-driven athletes and fitness lovers, fast-absorbing Gold Standard Whey with whey protein isolate supports muscle growth and repair after a workout. Our award-winning formula contains naturally occurring BCAAs and glutamine, plus 24 grams of quality, fast-absorbing whey protein powder per serving. That is the maker talking, not us, so read it as a claim rather than a finding. Buyers have it at 4.7 out of 5 from 2,416 ratings. We work out below what that is worth against everything else on the shelf.
We track 39 rated diet & nutrition products, and the middle of that pack scores 4.4 out of 5. This one is on 4.7. Top quarter of the shelf. In an aisle where nearly everything rates well, the distance above the middle is the part worth reading, and this one has it. Weighted for review volume, we place it fourth on this shelf.
2,416 people rated it, where the shelf median is 2,473. Enough reviews to trust the direction, not enough to close the question.
The shelf runs from £4.99 to £97.98 and the midpoint is about £12.00. On price, this one is in the top third. It costs more than most and is rated above most, so the premium at least tracks something buyers recognise.
