How it compares on the vitamin d shelf

We track 51 rated vitamin d products, and the middle of that pack scores 4.7 out of 5. This one is on 4.7. Mid-table, in other words. The stars aren't going to pick a winner here, so it comes down to pack size, cost per unit and the details further down.

That score rests on 875 ratings. The median for this shelf is 1,800. That's a solid enough base to read the score, though not enough to settle it.

Price-wise it falls in the bottom third of a shelf that stretches £3.50 to £29.99, with £8.49 in the middle. 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.
