DosFarma or PromoFarma for carnitine: which is better value per capsule

The short answer. For carnitine, DosFarma lists 9 products and PromoFarma another 15. By price per capsule, DosFarma’s median is €0.133/capsule and PromoFarma’s is €0.220/capsule. The highest scoring across both catalogues is ZENement L-Carnitina 180 Cápsulas Veganas from DosFarma, with 63 out of 100 at €0.105/capsule. The cheapest per capsule is Sotya L-Carnitina 600mg 90 cápsulas from DosFarma, at €0.055/capsule. Neither has products at verification level 4: for carnitine 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 capsule 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.

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 DosFarma and PromoFarma, for carnitine
IngredientDosFarmaPromoFarma
CarnitineEvidence-backed dose: from 2 g per serving600 mg7 of 9 contain it · 2 reach the dose500 mg4 of 15 contain it · 0 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 65 % more per capsule than DosFarma (€0.220/capsule against €0.133/capsule, 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.

Median rating at the storeBased on 4 reviews at DosFarma and 34 at PromoFarma. 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.5/54.3/5

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.
