One nutrient that can lessen warfarin's effectiveness is vitamin K. Vitamin K plays a key role in the body’s normal clotting process while also maintaining bone density and bone maintenance. The most practical approach to vitamin K intake for  is consistency. A consistent diet allows your doctor  to adjust your warfarin dose around a balanced, healthy diet that includes vitamin K.
