30 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 | Amazon | All other stores |
|---|---|---|
| Casein proteinEvidence-backed dose: from 20 g per serving | 33.1 g30 of 30 contain it · 8 reach the dose | 29.9 g54 of 54 contain it · 11 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
Amazon costs 2 % more per kg than All other stores (€41.40/kg against €40.76/kg, 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 | Amazon | 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. | €1.035 | €1.035 |
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 casein comparison: the only thing removed here is the products that do not meet the criterion above. How it is calculated.
