Can You Take Vitamin D and Warfarin Together?

What the interaction means

Warfarin's FDA label does not mention vitamin D (its only 'vitamin D' hits are taxonomy-list terms like 'PROVITAMIN D2 COMPOUND'). MedlinePlus's vitamin D page does not mention warfarin.

No documented interaction between Vitamin D and Warfarin was identified in the authoritative sources reviewed. This is not a guarantee that no interaction exists for every dose, formulation, or individual -- it means the sources checked did not document one.

Practical context

Both Vitamin D's and Warfarin's own current authoritative sources were checked directly, full text, in both directions; the taxonomy-list mentions were deliberately not treated as a real interaction claim.
