How it compares on the collagen shelf

The typical collagen product on our shelf scores 4.4 out of 5, measured across 55 rated products. This one comes in at 4.3. That lands in the bottom quarter. Nothing alarming on its own, though at this money you can find better-rated neighbours, so there should be a particular reason for choosing it.

That score rests on 3,500 ratings. The median for this shelf is 453. 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 top third of a shelf running from £7.99 to £38.50, with the midpoint around £19.96. 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.
