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 serving price. This ranks documentation, not health effects.
