Rat model links higher vitamin K needs to warfarin resistance; leaves open translation to human dosing or resistance management.

To determine the dietary vitamin K requirements and physiological anticoagulant responses in rat strains displaying resistance to warfarin.
Evaluated baseline and dietary requirements of vitamin K in warfarin-resistant laboratory and wild-derived rat models.
Administered coumarin anticoagulant challenges to assess coagulation competence and drug response thresholds.
Warfarin-resistant rats exhibit an elevated nutritional requirement for dietary vitamin K compared to susceptible counterparts.
Resistance mechanisms confer marked insensitivity to standard anticoagulant doses, preventing the typical disruption of vitamin K-dependent clotting.
