Hunter & Gather Marine Collagen Powder 300g - Pure Unflavoured 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: We only source the highest quality and optimally bioavailable marine collagen peptides. Our marine collagen powder contains 18 amino acids which provide a super boost for healthy hair. Collagen is a fantastic way to boost essential glycine intake which helps the body fulfil a wide range of health and wellness goals. That is the maker talking, not us, so read it as a claim rather than a finding. Buyers have it at 4.0 out of 5 from 505 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 4.0. That's inside the bottom quarter of the shelf. It isn't a warning, but better-rated options do sit alongside it at similar money, so you would want a specific reason to pick this one.
Behind that score sit 505 ratings, against a shelf median of 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. Paying above the middle of the shelf needs a reason the star rating does not supply, because on ratings alone the extra money is not buying an advantage here.
