Coumadin vs. Vitamin K?

I’m on Coumadin. Do I have to avoid foods with vitamin K?

Coumadin, or Warfarin, is a blood thinner. Vitamin K helps the blood clot, which is the opposite of what you want. But that doesn’t mean you have to avoid vitamin K rich foods. People taking Coumadin can typically have small and consistent amounts each day or several times a week. Don’t overdo it and, again, be consistent. Vitamin K rich foods include green leafy veggies such as spinach, kale, broccoli, chard, brussels sprouts, mustard greens, cabbage, collard greens, romaine and green leaf lettuce, endive, turnip greens and green tea. Garlic, and other herbs and herb supplements, when taken with Coumadin can increase the chance of bleeding and bruising. Please tell your doctor about all over-the-counter vitamins, minerals and herbs you’re taking, as some should be avoided. I also suggest you work with your health care provider regarding regular blood checks, foods to limit and any changes needed to medication dosage.
