† 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.

45 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 |
|---|---|---|
| CarnitineEvidence-backed dose: from 2 g per serving | 1 g22 of 45 contain it · 7 reach the dose | 600 mg16 of 48 contain it · 2 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 8 % more per capsule than Amazon (€0.198/capsule against €0.183/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: capsules per pack (median), products with declared additives.
| Factor | Amazon | All other stores |
|---|---|---|
| Cost of one effective doseHere the comparison flips: Amazon 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. | €0.450 | €0.415 |
| Capsules per pack (median)Amazon sells bigger packs, and a big pack spreads the same tub, the same label and the same shipping over more capsules. Part of the price gap per capsule is this and not a discount: comparing one store’s small pack with the other’s large one inflates the gap. | 120 caps. | 90 caps. |
| Products with declared additivesWhat the pages of both declare: anti-caking agents, colourings. 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 % | 23 % |
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 carnitine comparison: the only thing removed here is the products that do not meet the criterion above. How it is calculated.
