† 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
All other stores costs 103 % more per capsule than DosFarma (€0.388/capsule against €0.191/capsule, medians of both catalogues). Going by what both pages declare, there are no differences in composition or pack size that explain it: here the gap is the store’s pricing policy.
| Factor | DosFarma | All other stores |
|---|---|---|
| Median rating at the storeBased on 33 reviews at DosFarma and 47 at All other stores. 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 | 4.8/5 |
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.
This is a filter, not another ranking. The score that sorts this table is exactly the same as in the full tryptophan comparison: the only thing removed here is the products that do not meet the criterion above. How it is calculated.
