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.
As mentioned earlier, warfarin works by preventing the recycling of vitamin K, diminishing levels of the vitamin available to the body, and contributing to weaker bones and increased fractures. 23 This problem is compounded by the fact that many of the people using warfarin are elderly and already have osteoporosis and compromised bone integrity.
