Coumadin & Vitamin K
Alice wrote about 3 years ago
I was told because both Vit K and Coumadin have a relatively long half-life, I have to consume a consistent intake of Vitamin K foods throughout the week. I understand my diet needs to be consistent on a weekly basis. What I don't understand is how consistent does my V-K intake have to be from day to day? Is there a variance threshold of Vitamin K intake from day to day that will adversely affect my Coumadin therapy? i.e. Is it ok for my daily intake to vary 100 mcg's or even 500 mcg's as long as my weekly total is consistent?
