The monitoring of dietary Vitamin K levels is critical for over 20 million Americans taking the blood thinning medication Warfarin (Coumadin) each year. Unfortunately, Vitamin K levels are not commonly listed on most nutrition labels, making it difficult to keep track of Vitamin K intake. The medication is commonly taken by people who have heart rhythm problems or mechanical heart valves and has a very narrow therapeutic range. If levels get too high, patients can bleed profusely. If levels get too low, patients can have strokes, heart attacks, or blood clots in their lungs (pulmonary emboli). We ask the administration to consider requiring food producers to include Vitamin K levels on nutrition labels in an effort to help 20 million Americans proactively take charge of their health.
