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.
You need vitamin K to help your blood to clot and to keep your bones strong. If you are taking the blood thinner warfarin (Coumadin), you will need to keep the amount of vitamin K in your diet steady. If you vary the amount of vitamin K too much, your doctor may have to change your dose of warfarin often. Most people who take warfarin can eat a normal diet. But it is important not to suddenly eat a lot more or a lot less food that is high in vitamin K than you normally do.
