How we compare magnesium

Every product gets the same benchmark: 1.000 mg elemental magnesium. We divide the pack price by the amount of elemental magnesium it contains and scale that to the benchmark, so a 500 g tub compares fairly with 1 kg, and powder with capsules.

price per 1.000 mg = pack price ÷ amount of elemental magnesium in the pack × 1.000 mg

Bundle deals (e.g. "2 for 1") are included via a multiplier. Out-of-stock products are hidden by default. The ranking is never for sale; we only earn a commission if you buy through a link. Read the full method →
