Answer From Francisco Lopez-Jimenez, M.D. Warfarin is a blood-thinning medication that helps treat and prevent blood clots. There's no special diet for people who take warfarin. However, certain foods and drinks can make warfarin work not as well at preventing blood clots. It's important to pay attention to what you eat while taking warfarin. For example, vitamin K can make warfarin less effective. So, it's important to get about the same amount of vitamin K every day. The recommended intake level of vitamin K for adult men is 120 micrograms (mcg). For adult women, it's 90 mcg. To keep vitamin K intake consistent, avoid changing the amounts of vitamin K-rich foods or drinks you have from day to day or week to week. Vitamin K-rich foods include: Kale Spinach Brussels sprouts Collard greens Mustard green Turnip greens Swiss chard Broccoli Asparagus Chamomile or green tea Seaweed Certain drinks when taking warfarin might lead to bleeding problems. Avoid or drink only small amounts of these when taking warfarin: Cranberry juice Grapefruit juice Alcohol Talk to your health care provider before making major changes in your diet and before starting medications, vitamins or herbal supplements. If you can't eat for several days or have ongoing stomach upset, diarrhea or fever, call your provider.
