Which is the cheapest magnesium?

Magnesio 365 Cápsulas Veganas from Amazon, at €0.049/capsule (365 capsules pack for 17,95 €). It sits at verification level 1 out of 4. Cheap is not the same as well scored: price is 35 % of the mark and most of the rest is how verifiable its certification is.

How much does a capsule of magnesium cost?

Between €0.049/capsule and €0.783/capsule across the 13 stores compared, with a median of €0.121/capsule. That is the price per capsule, not per pack: two tubs at the same price can cost twice as much as each other depending on what is inside.

What certification should magnesium have?

Of the 154 products compared, 0 reach level 4 (the certification is backed by a third party: either we checked it with the body that issues it, or the product carries in its name a trademark that requires a third party behind it, such as Creapure or IFOS) and 0 reach level 3 (a lab report published by the brand itself). The remaining 154 stop at a certification claimed on the product page, or none at all. Only level 4 is checked against whoever issues the certification.

How much magnesium should you take a day?

The reference dose this site uses for magnesium is 375 mg a day, with moderate evidence. Source: Reglamento (UE) 1169/2011 sobre la informacion alimentaria facilitada al consumidor, Anexo XIII: valores de referencia de nutrientes. Magnesio, 375 mg. Es un valor de ETIQUETADO, no una dosis con efecto demostrado: mide cuanto cubre una capsula de lo que se considera la ingesta de referencia diaria.. That is the dose of the ingredient in the study cited, not a recommendation for you nor a claim about any product in the table.

Questions about magnesium

Answered with the data on this page

Which magnesium should you buy?: Santiveri Santiveres Cloruro de Magnesio 200 caps from PromoFarma, with 80 points out of 100 at €0.042/capsule. The mark is 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, and no commercial deal moves the ranking.
Which is the cheapest magnesium?: Magnesio 365 Cápsulas Veganas from Amazon, at €0.049/capsule (365 capsules pack for 17,95 €). It sits at verification level 1 out of 4. Cheap is not the same as well scored: price is 35 % of the mark and most of the rest is how verifiable its certification is.
How much does a capsule of magnesium cost?: Between €0.049/capsule and €0.783/capsule across the 13 stores compared, with a median of €0.121/capsule. That is the price per capsule, not per pack: two tubs at the same price can cost twice as much as each other depending on what is inside.
What certification should magnesium have?: Of the 154 products compared, 0 reach level 4 (the certification is backed by a third party: either we checked it with the body that issues it, or the product carries in its name a trademark that requires a third party behind it, such as Creapure or IFOS) and 0 reach level 3 (a lab report published by the brand itself). The remaining 154 stop at a certification claimed on the product page, or none at all. Only level 4 is checked against whoever issues the certification.
How much magnesium should you take a day?: The reference dose this site uses for magnesium is 375 mg a day, with moderate evidence. Source: Reglamento (UE) 1169/2011 sobre la informacion alimentaria facilitada al consumidor, Anexo XIII: valores de referencia de nutrientes. Magnesio, 375 mg. Es un valor de ETIQUETADO, no una dosis con efecto demostrado: mide cuanto cubre una capsula de lo que se considera la ingesta de referencia diaria.. That is the dose of the ingredient in the study cited, not a recommendation for you nor a claim about any product in the table.
