Compare magnesium by effective dose, not bottle price.
A £35 magnesium product may not be expensive if it delivers significantly more elemental magnesium per serving. A £10 product may not be good value if the elemental dose is low. FairDose compares like-for-like — by form, elemental dose and cost per effective dose.

Compare by form
7 forms · 1 liveMagnesium forms are not interchangeable on price. Each form gets its own comparison engine.
Like-for-like, by form
Glycinate is compared with glycinate. Citrate with citrate. Forms are never blended into a single league table.
Elemental dose is the unit
We normalise on elemental magnesium per serving, not compound weight. The label number that actually matters.
Cost per effective dose
Cost per 100mg and 200mg elemental — not cost per bottle. Bottle size tricks disappear.
