Taken from the wording on the listing itself and the price we track, not from a brand claim about value. How we rank →
The typical vitamin d product on our shelf scores 4.7 out of 5, measured across 51 rated products. This one comes in at 4.6. 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 37,000 ratings. The median for this shelf is 1,800. 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 middle third of a shelf running from £3.50 to £29.99, with the midpoint around £8.49. That's where most sensible buys land, neither the cheapest thing on the shelf nor the one you pay a name for.
