Your body needs vitamin K to clot blood and keep your bones strong. It's found in leafy green vegetables such as kale and spinach.
If you take the blood thinner warfarin (Coumadin), you need to be careful about how much vitamin K you get. Vitamin K can keep your warfarin from working as it should.
Most people who take warfarin can eat normally. The important thing is to get about the same amount of vitamin K each day. Don't suddenly start eating foods with a lot more or a lot less vitamin K.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
You don't need to stop eating food high in vitamin K. But you do need to eat about the same amount each day.
