Vitamin K question

I copied this line from the section on healthy eating.  "If you’re on an anticoagulant medication, it’s also important to remember to pay attention to those foods that are high in vitamin K."  It doesn't say whether you need to consume more​ foods with high vitamin K or get less ​vitamin K.  I found that to be a poorly written sentance with nothing further to say why you are paying attention to those that are high. Does anyone know the rest of this story?  Thanks

    Hello, MrsZee!  If you are taking warfarin (coumadin) as an anticoagulant, it is can be necessary to monitor the amount of foods you eat containing Vitamin K in order to keep your blood at the desirable level..  However, if taking one of the newer anti coagulants such as Eliquis, Pradaxa, or Xarelto, it is not necessary to monitor the Vitamin K intake.  Thanks for posting this question and I hope you will continue to contribute to our forum. Hope this answers your question.Best wishes to you,Jean  ( My AibExperiencne Comunnity Leader)

    Eating foods high with vitamin K can change the blood level of Coumadin. Vitamin K is the antidote for some one bleeding because their blood levels are too high with Coumadin. Therefore it is recommended you avoid those foods or eat in moderation. Your doctor would inform you of their recommendations.   They do not affect  the others like Eliquis, Pradaxa and Xarelto.

    Thanks you two  for clearing that up.  I was on Pradaxa for only a very short time as my AFib stopped on its own.  And since I have been taking magnesium, I haven't had a reoccurance.  So, my doc has recommended just an aspirin for now anyway.  So, for now I won't have to check for that.  I still cannot say whether or not the MG has had anything to do with it but so far no reoccurances.

    That’s good to hear. Good luck with your Afib journey.

    MrsZee - I am curious how much Mg and how often and if a particular kind or brand. I just started a Mg and potassium combo for the same purpose.  Not afib free but seems less often and much less of the racing heart episodes.

    Vitamin K is usually only an issue with Coumadin as it affects your clotting levels. The new anticoagulants like Pradaxa, Xarelto, and Elequis are not affected.

    Zark - I am just taking 250mg of magnesium and at a different time of day I take a Centrum Silver for Women multi.  That has 100 mg of magnesium.  That is the most a woman should take from supplements according to the site.  The brand I take is Jaimeson  which is Canadian as I am living in Canada right now and that was what they had at the store.  I just wanted to try it and get it in my system right away.  Its magnesium oxide and some people have posted that it could be harder for your body to absorb and tough on your tummy.  My long term goal is to get most of my nutrient from food.  My plan is a spreadsheet with all of the foods I normally eat and how much calcium, D, potassium and magnesium they contain.  But that is going to take some time to assemble.  I am not certain that I was getting all of what I need EVERY day.  Some days for sure, but not all.

    When that content was written, the idea was that those who are on anticoagulants (many of whom don't always know which kind of anticoagulant they are on) need to be aware and to check into whether Vitamin K affects their anticoagulant. Only those on Coumadin (warfarin), including the various other names for it, need to be concerned about Vitamin K, and the key to that is to eat a consistent amount of Vitamin K each day. For those who are on Coumadin (warfarin), this guide will help you know what foods are high and low when it comes to Vitamin K: Those on the newer anticoagulants that are referred to as NOACs or DOACs do not need to be concerned. The list of NOACs/DOACs includes Pradaxa/Pradax (dabigatran), Xarelto (rivaroxaban), Eliquis (apixaban), and Savaysa/Lixiana (edoxaban). Mellanie

    Green vegetables are high in vitamin K and that can coagulate your blood. If you have afib you are supposed to watch the amount of green vegetable intake. You can consume a suitable amount regularly and maintain your INR (blood thickness) between an ideal range. The purpose is to avoid getting a stroke.
