DosFarma or PromoFarma for vitamin D: which is better value per capsule
The short answer. For vitamin D, DosFarma lists 15 products and PromoFarma another 15. By price per capsule, DosFarma’s median is €0.200/capsule and PromoFarma’s is €0.233/capsule. The highest scoring across both catalogues is Hivital Foods Hivital Vitamina D3 4000 UI 300 perlas from PromoFarma, with 63 out of 100 at €0.053/capsule. The cheapest per capsule is A.Vogel Urticalcin Vitamina D 600 Comprimidos from DosFarma, at €0.037/capsule. Neither has products at verification level 4: for vitamin D the ceiling today is a lab report published by the brand itself, and that is not a certification.
Both stores measured on the same criterion: price per capsule and certification verification level. There is no overall winner because there isn’t one: one can win on price and the other on certification, and here you see both separately.
† Some links are affiliate links — they do not change the ranking
Some store links are affiliate links: if you buy through them, this site may earn a commission at no extra cost to you. It changes nothing in the ranking: the score is computed beforehand and without reading those links, and products with no affiliate programme appear exactly the same. How it is calculated.

Why one is cheaper than the other
Factor by factor, with both stores’ data
PromoFarma costs 17 % more per capsule than DosFarma (€0.233/capsule against €0.200/capsule, medians of both catalogues). That difference does not come out of nowhere. These are the data that explain it, with each store’s figure alongside: capsules per pack (median).
| Factor | DosFarma | PromoFarma |
|---|---|---|
| Capsules per pack (median)DosFarma sells bigger packs, and a big pack spreads the same tub, the same label and the same shipping over more capsules. Part of the price gap per capsule is this and not a discount: comparing one store’s small pack with the other’s large one inflates the gap. | 100 caps. | 60 caps. |
| Median rating at the storeBased on 13 reviews at DosFarma and 19 at PromoFarma. These are the store’s own ratings, which is judge and party: they help spot a product that arrives damaged or tastes awful, not decide which formula is better. | 5/5 | 5/5 |
None of these factors is an accusation. They are medians of what each store publishes on its pages on the day prices were collected: where a page does not declare a figure, that store does not count in that row instead of counting as a zero. A specific product can contradict its store’s median, and that is what the full table is for. How all of this is calculated.
