RKPROUC Multi Collagen Peptides Powder, 1 lb Unflavored sits on our collagen shelf, where the ranking comes from what buyers actually said rather than from what the box says. From the seller's own listing: 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. On Amazon it sits at 4.4 out of 5 across 77 ratings. How that compares with the rest of the shelf is below.

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 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.
77 people rated it, where the shelf median is 453. 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 £7.99 to £38.50, with the midpoint around £19.96. Cheap with a middling rating is a fair trade if the specifics suit you, and it is the usual reason to pick something at this end of the shelf.
