Optimum Nutrition Micronised Creatine Monohydrate Powder, 317g | Unflavoured sits on our creatine shelf, where the ranking comes from what buyers actually said rather than from what the box says. From the seller's own listing: 100% pure creatine monohydrate with a micronised formula that makes it easy to absorb, improves performance & muscle power during high-intensity training*; helps support ATP recycling. Fuels muscles during high-intensity workouts* while supporting performance across successive training sessions for both experienced athletes and beginners. That is the maker talking, not us, so read it as a claim rather than a finding. It holds 4.6 out of 5 on Amazon from 21,200 ratings. Where that leaves it next to the rest of the shelf is set out below.
The serving count on this tub is worked out at 3.4 g. The dose used in most creatine research, and the one most people take daily, is 5 g. At 5 g this tub holds 63 servings rather than 93.
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 48 rated creatine products we track, the middle of the pack sits at 4.6 out of 5. This one scores 4.6. That sits mid-table. Ratings this close together don't decide anything on their own, so weigh pack size, price per unit and the specifics below instead.
21,200 people rated it, where the shelf median is 408. A score built on that many opinions is hard to shift and hard to game, which is why we weight review volume rather than ranking on stars alone.
On money, this sits in the middle third of a shelf running from £6.98 to £52.90, with the midpoint around £17.99. That's where most sensible buys land, neither the cheapest thing on the shelf nor the one you pay a name for.
