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.
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.
