How it compares on the vitamin d shelf

The typical vitamin d product on our shelf scores 4.7 out of 5, measured across 51 rated products. This one comes in at 4.8. That puts it in the top quarter of the shelf. Most things here rate well, so what matters is the gap to the pack rather than the number on its own, and the gap is real.

That score rests on 42 ratings. The median for this shelf is 1,800. 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 £3.50 to £29.99, with the midpoint around £8.99. Cheaper than most while rating above the middle of the shelf is the combination we look for, and it is the strongest thing this one has going for it.
