Claim handling
We label purchase terms as vendor-reported and do not turn ingredient research into finished-product claims. Where evidence is uncertain or heterogeneous, we say so.
Updates
Commercial details can change. Important product and buyer pages display a last-updated date and encourage readers to verify live terms before purchasing.
