We keep Optimum Nutrition Collagen Peptides Powder, Hydrolyzed Bovine Collagen with on our collagen shelf alongside 54 others, and rank it on rating, review volume and live price rather than on the brand. The manufacturer puts it this way: Supports normal collagen formation contributing to the normal and healthy function of joints. Each serving contains 20g of high-quality hydrolyzed bovine collagen peptides for easy digestion and absorption. That is the maker talking, not us, so read it as a claim rather than a finding. Buyers have it at 4.4 out of 5 from 105 ratings. We work out below what that is worth against everything else on the shelf.

The dose above is per serving, and a serving is often more than one capsule. We do not publish a cost per 10 g of collagen on this shelf because the listings rarely say how many capsules make a serving, and multiplying by the capsule count would overstate what you get.
Taken from the wording on the listing itself and the price we track, not from a brand claim about value. How we rank →
We track 55 rated collagen products, and the middle of that pack scores 4.4 out of 5. This one is on 4.4. Mid-table, in other words. The stars aren't going to pick a winner here, so it comes down to pack size, cost per unit and the details further down.
That score rests on 105 ratings. The median for this shelf is 453. 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 £7.99 to £38.50, with £19.96 in the middle. It costs more than most while rating around the middle, so the extra money needs to be buying something specific: pack size, brand you trust, or a detail below that matters to you.
