The best cheap magnesium: 78 below €0.121/capsule

The short answer. Of the 78 products that pass this filter, the highest scoring is Santiveri Santiveres Cloruro de Magnesio 200 caps from PromoFarma: €0.042/capsule and verification level 1 out of 4. The cheapest per capsule is Magnesio 365 Cápsulas Veganas from Amazon, at €0.049/capsule. The selection runs from €0.049/capsule to €0.121/capsule, with a median of €0.083/capsule.

The cheaper half of the category: the 78 magnesium products that cost €0.121/capsule or less, which is the median of the 154 compared. They run from €0.049/capsule to €0.121/capsule. Cheap is not the same as good: the order is still the score: 35 % price against the cheapest in the category, 35 % verifiable quality (certification, purity and additives), 20 % the category's own requirements and 10 % the buyers' rating at the store.

† 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.
