Serious — worth a conversationCan you take Vitamin K with blood thinners (warfarin type)?

Warfarin works by blocking vitamin K recycling. Supplemental K swings your INR and can push you into clot territory.
Drugs in this class include Warfarin / Coumadin, Apixaban / Eliquis, Rivaroxaban / Xarelto.
What to do about it
The clinic managing your INR needs to know about any change to vitamin K intake, in either direction.
This is general information compiled from published pharmacology, not
advice about your situation. Your dose, your other medication and your bloodwork all matter,
and a pharmacist can see those in a way this page cannot.
