Warfarin (coumadin) is a blood thinner that decreases the chance for a blood clot. Foods high in vitamin K can interfere with the efficacy of warfarin, thus making it more likely that one could clot. Vitamin K is involved in clot formation in the body.
There are also foods that can do just the opposite and increase the effects of Warfarin-making it more likely that an individual could develop a bleed (ex: intestinal). Examples of foods/drinks that may potentially interact:
DECREASE THE EFFICACY OF WARFARIN (Higher risk to clot)
- Kale 1/2 cup 531 mcg
- Mustard Greens raw 1 cup 279 mcg
- Spinach 1/2 cup cooked 444 mcg
- Collard Greens 1/2 cup cooked 418 mcg
- Parsley 1/4 cup 246 mcg
INCREASE THE EFFECTS OF WARFARIN (Higher risk to bleed)
- Garlic oil supplements
- Cranberry juice
- Vitamin E supplements
