Warfarin interferes with how your liver uses vitamin K taken from your diet. Some foods are rich in vitamin K and these can affect how warfarin works. As part of a healthy balanced diet, you can continue to eat foods that contain vitamin K in moderate amounts. You don’t need to change your regular eating habits. There is no “correct” amount of vitamin K that you should eat. But, it is important to avoid large changes in the amount of food you eat containing vitamin K.
It is also important to consider the amount of vitamin K you are eating in situations when your diet may change, such as during illness, travel, fad diets, hospitalisation and after surgery. Before making any changes to your diet talk to your health professional.
