Reference figure: elemental magnesium
Magnesium compared
Every variant is normalised to elemental magnesium per serving — regardless of compound, package size or dosage form.
Documented batch measurements first, then linked lab reports and sourced declarations. Reports with measurements outside a stated criterion rank last. Equal evidence is ordered by active-ingredient price. This ranks documentation, not health effects.
The range in this list is wide — per gram of active ingredient, the most expensive entry costs about 17× the cheapest. That is not a fault in the table: depending on the compound, a capsule holds many times less active ingredient than the same amount of powder. This column is what makes that difference visible.
