A member asked:
What ordinary foods can affect coumadin (warfarin) therapy?
A doctor has provided 1 answer
Vitamin K foods: Coumadin (warfarin) acts against Vitamin K in the blood clotting reaction process, Therefore, foods high in this vitamin act to reduce the efficacy of Coumadin (warfarin). Green leafy vegetables are high in Vitamin K as are others that you can search. Be aware, bacteria in the gut produce Vitamin K, so antibiotics reducing them can reduce vitamin production and enhance Coumadin (warfarin) effects.
