Which is the cheapest vegan protein across the two stores?

Sevenhills Wholefoods Proteína De Cáñamo Cruda En Polvo Orgánico 1.8 kg from Amazon, at €13.44/kg (1800 g pack for €24.19), at verification level 1 out of 4.

Why don’t Amazon and PromoFarma cost the same?

PromoFarma costs 45 % more per kg than Amazon (€42.12/kg against €29.00/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). Price per kg and price per dose point to the same store, so the dose does not erase the label difference: Amazon is cheaper both ways. Amazon 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.

Which of the two stores scores better?

Sevenhills Wholefoods Proteína De Cáñamo Cruda En Polvo Orgánico 1.8 kg from Amazon, with 62 out of 100.

Amazon or PromoFarma for vegan protein: which is better value per kg

The short answer. For vegan protein, Amazon lists 52 products and PromoFarma another 14. By price per kg, Amazon’s median is €29.00/kg and PromoFarma’s is €42.12/kg. The highest scoring across both catalogues is Sevenhills Wholefoods Proteína De Cáñamo Cruda En Polvo Orgánico 1.8 kg from Amazon, with 62 out of 100 at €13.44/kg. Neither has products at verification level 4: for vegan protein 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 kg 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.

Amazon against PromoFarma, figure by figure

The same numbers for both

Amazon and PromoFarma for vegan protein, with prices from October 15, 2026
Figure	Amazon	PromoFarma
Products compared	52	14
Median per kg	€29.00/kg	€42.12/kg
Cheapest per kg	€13.44/kg	€17.80/kg
Dearest per kg	€71.60/kg	€58.73/kg
Best score	62	57
Level 4 (certification backed by a third party)	0 of 52	0 of 14
Level 3 (the brand’s own lab report)	0 of 52	0 of 14

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.

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).

Ingredients and dose per serving at Amazon and PromoFarma, for vegan protein
Ingredient	Amazon	PromoFarma
Plant proteinEvidence-backed dose: from 20 g per serving	30 g52 of 52 contain it · 8 reach the dose	—14 of 14 contain it · none publishes 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 45 % more per kg than Amazon (€42.12/kg against €29.00/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).

Where the price difference between Amazon and PromoFarma for vegan protein comes from
Factor	Amazon	PromoFarma
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: Amazon is cheaper both ways.	€0.725	€1.053
Pack size (median)Amazon 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.	750 g	400 g

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.
