Best Magnesium is owned by Dan d’Auvergne through Foundlab. It compares selected Australian magnesium listings using the numbers the brand or retailer actually publishes.
We started with a cross-section of forms, formats, prices and retailers for which the exact pack, price and elemental magnesium figure could be verified. The first 30 records were checked on 22 October 2026. Inclusion does not imply endorsement.
Cost is normalised to 100 mg of elemental magnesium using the stated amount and selected pack. The data also shows compound weight when published, serving units and forms. We do not assign an overall health score.
Foundlab summarises publicly available labels, brand and retailer pages, government information and linked research. Each product record includes its source and check date. The evidence notes link to the studies they discuss.
