I take Coumadin because of a mitral valve replacement. Does the vitamin K content, in proportion to the amount used in most recipes, have any impact on the effectiveness of Coumadin?
Vitamin K has a great effect on coumadin's ability to decrease blood clotting. It is commonly used for coumadin over dosages. There is not enough Vitamin K in olive oil though, to be concerned about. There are some foods which can affect your INR or blood clotting test results. As long as you eat roughly the same amount of these foods every day your doctor or anticoagulation nurse can adjust your coumadin dose accordingly.
