We keep RKPROUC Collagen Peptide Powder,16 oz (41 Servings)-Hydrolyzed Collagen 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: Scoop, swirl, and sip—this unflavored powder blends smoothly into coffee, tea, smoothies, or shakes without altering the taste. For the best texture. Our collagen for men and women is enriched with vitamin C and biotin to promote healthy hair, skin, and nails. Combined with our grass fed collagen peptides. 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 56 ratings. We work out below what that is worth against everything else on the shelf.
Shelf price range checked · details
Across the 55 rated collagen products we track, the middle of the pack sits at 4.4 out of 5. This one scores 4.4. That's mid-table. Star ratings won't separate this from its neighbours, so the decision comes down to pack size, price per unit and whether the specifics below suit you.
Behind that score sit 56 ratings, against a shelf median of 453. That isn't much to go on by the standards of this shelf. Scores this lightly reviewed move easily, so take it as a first impression.
Price-wise it falls in the middle third of a shelf that stretches £7.99 to £38.50, with £19.96 in the middle. That's the middle of the shelf, which is usually the least regretted place to buy from.
