The uncoordinated use of the metric system by different scientific and engineering disciplines, particularly in the late 19th century, resulted in different choices of base units even though all were based on the same definitions of the metre and the kilogram.
Traditionally, patients taking warfarin have been advised to avoid vitamin K to prevent excess clotting. Surprisingly, scientists have now discovered that regular consumption of a modest amount of vitamin K actually helps stabilize the anticoagulant effects of warfarin. Vitamin K intake may thus help individuals using warfarin achieve the therapeutic benefits of the drugâwithout danger of clots or bleeding.
Also, reducing the amount of vitamin K in your diet may make it more difficult to manage your warfarin therapy. Patients who have a low intake of vitamin K have been found to have more fluctuation in their INR, which is the test used to measure the effect of warfarin and to adjust the dose of warfarin. For more information on the INR, please review the Understanding the PT-INR Test section of ClotCare.
