DosFarma or PromoFarma for B complex: which is better value per capsule
The short answer. For B complex, DosFarma lists 15 products and PromoFarma another 15. By price per capsule, DosFarma’s median is €0.216/capsule and PromoFarma’s is €0.608/capsule. The highest scoring across both catalogues is Aldous Bio Vitamina B Complex + Vitamina C 400 Comprimidos from DosFarma, with 72 out of 100 at €0.062/capsule. Neither has products at verification level 4: for B complex 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.

The median is not the price you will pay. It is the midpoint of that store’s catalogue in this category, and it tells you whether a store is dear or cheap overall. For buying, the specific row in the table below is what counts.
Why one is cheaper than the other
Factor by factor, with both stores’ data
PromoFarma costs 181 % more per capsule than DosFarma (€0.608/capsule against €0.216/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: different brands in the catalogue.
| Factor | DosFarma | PromoFarma |
|---|---|---|
| Different brands in the cataloguePromoFarma mostly sells one brand, Airbiotic: 60 % of its catalogue in this category. DosFarma spreads its own across 12 brands. A store selling its own brand skips the manufacturer’s margin and can cut the price without touching the formula; a reseller pays that margin and passes it on, and in exchange carries brands the other does not sell. | 12 (13 % Solgar) | 6 (60 % Airbiotic) |
| Median rating at the storeBased on 5 reviews at DosFarma and 4 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.
