The amount of vitamin K in your diet can affect the amount (dose) of. warfarin you need to take. Your medicine dose must be balanced with your. diet to allow the drug to work correctly. A few things to remember when taking warfarin: You want a medium or moderate amount of vitamin K in the foods you. eat.
Eating more or less of. these foods than usual may change the way warfarin works in your body. and may increase your risk of bleeding or blood clots. For example: if. you eat cooked greens, it is much better to eat Â½ cup each day instead of. eating 2 or 3 cups once a week.
