Vitamin K is an essential vitamin that is important for the synthesis of several coagulation factors. Patients on coumadin need to keep their dietary intake of vitamin K constant once they are titrated to the proper dose. A sudden change in intake can increase or decrease the level of anticoagulation with consequent risks for bleeding or thrombosis.
Source of vitamin K:
(1) daily diet
(2) vitamins
The amount of vitamin K in common foods is shown in the following table that shows those foods and beverages with an amount >= 1 microgram per 100 grams of the food. The table in PT-104 includes foods with trace or fractional quantities of the vitamin.
