9 products in this table
What each tub contains
Median dose per serving
Price per kilo does not tell you how much active ingredient is inside the kilo. This table does: for each ingredient, the median dose per serving at each store and how many products reach the dose backed by studies (the same reference this site scores with).
| Ingredient | DosFarma | All other stores |
|---|---|---|
| ZincEvidence-backed dose: from 10 mg per serving | 50 mg4 of 9 contain it · 4 reach the dose | 25 mg8 of 72 contain it · 8 reach the dose |
The dose is per serving, not per tub. A big tub with a short dose forces you to take two scoops to get the same, and then it lasts half as long: that is why the price per dose in the next section does not match the price per kilo.
Why one is cheaper than the other
Factor by factor, with both stores’ data
All other stores costs 2 % more per capsule than DosFarma (€0.164/capsule against €0.160/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: products with declared additives, chemical form of the active ingredient.
| Factor | DosFarma | All other stores |
|---|---|---|
| Cost of one effective doseHere the comparison flips: DosFarma wins per capsule and All other stores wins per dose. Price per capsule measures powder or capsules; this measures what you have to take for the ingredient to do what the study says, which is what you end up paying for. | €0.150 | €0.138 |
| Products with declared additivesWhat the pages of both declare: anti-caking agents. An additive is not fraud, but it takes up grams that are not active ingredient and is cheaper than the active ingredient: where more additive is declared, the price per capsule drops without the product being better. | 0 % | 22 % |
| Chemical form of the active ingredientDosFarma: Citrate (1). All other stores: Citrate (7), Gluconate (4). The form changes the manufacturing cost and the evidence behind it, so two tubs of the same ingredient at different prices may not be the same product. | Citrate 1 | Citrate 7 · Gluconate 4 |
| Median rating at the storeBased on 10 reviews at DosFarma and 788 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 | 4.7/5 |
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 zinc comparison: the only thing removed here is the products that do not meet the criterion above. How it is calculated.
