How Suppio ranks

Suppio matches identical products across UK retailers by barcode, then ranks by price per active dose rather than sticker price. Value rankings only ever include listings Suppio has independently verified against the live retailer page - unverified data is shown on each product’s own page but excluded from ranking.

Prices across our retailer network are refreshed at least daily.
