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 | PromoFarma | All other stores |
|---|---|---|
| Plant proteinEvidence-backed dose: from 20 g per serving | —14 of 14 contain it · none publishes the dose | 30 g127 of 127 contain it · 27 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
PromoFarma costs 57 % more per kg than All other stores (€42.12/kg against €26.79/kg, 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: pack size (median), products with declared additives.
| Factor | PromoFarma | All other stores |
|---|---|---|
| Cost of one effective dosePrice per kg and price per dose point to the same store, so the dose does not erase the label difference: All other stores is cheaper both ways. | €1.053 | €0.746 |
| Pack size (median)All other stores sells bigger packs, and a big pack spreads the same tub, the same label and the same shipping over more kilos. Part of the price gap per kg is this and not a discount: comparing one store’s small pack with the other’s large one inflates the gap. | 400 g | 900 g |
| Products with declared additivesWhat the pages of both declare: colourings, artificial sweeteners, 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 kg drops without the product being better. | 0 % | 17 % |
| Median rating at the storeBased on 3 reviews at PromoFarma and 17,901 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 | 4.5/5 |
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.
This is a filter, not another ranking. The score that sorts this table is exactly the same as in the full vegan protein comparison: the only thing removed here is the products that do not meet the criterion above. How it is calculated.
