Spinach/Vitamin K.

  1. 0
    I know Vitamin K is the antidote for Coumadin and spinach is a notorious veggie with Vit K in it... So if you eat a lot of spinach, could you get a blood clot from it?

    These are the things I think about when I'm eating dinner . I ate a whole can of spinach and now I'm wondering about the clot issue, especially since I'm on BCP. (Not that I'm concerned I'll get a clot, but just one of those "What if" things) It's probably a stupid question, tho lol.



    (You can get renal calculi from a spinach overdose, too, right?)

    If you're worried about getting a clot from eating spinach & being on BCPs then a call to your doc might set your mind at ease. If you're just wondering, you know.

    Oh, I'm not worried about getting a clot, but I'm just curious... Like if someone overdoses on spinach would they get a clot?

    Sorry,I've been working night shift with minimal sleep, so I'm probably delirious.

    Is it oxalate stones that you are thinking of with spinach? I can't remember. I don't think that's an issue unless that's an issue...

    Unless I am wrong. It is not that spinach can cause clots. It is the vit K in it that counteracts the coumadin which then places the person to be out of therapeutic range. I am not sure how much Vit K is needed to render to coumadin useless though.

    I don't think we're worried about dietary Vitamin K. Isn't protamine the antidote for coumadin?

    I am a Nutrition Specialist. Here is research-based information that is accurate on Spinach/Vitamin K.

    The main dietary concern related to taking warfarin has to do with the amount of vitamin K in your diet. Vitamin K plays an important role in blood clotting. Warfarin works to reduce clotting by diminishing the activity of vitamin K. Eating large amounts of vitamin K can counteract the benefits of warfarin. The goal is to keep your Vitamin K intake as consistent as possible.

    Sudden increase of Vitamin K could decrease the effect of Coumadin. On the other hand, greatly lowering your Vitamin K could increase the effect of Coumadin.
    • Limit foods "high" in Vitam in Vitamin K to no more than 1 serving a day.
    • Limit foods "moderately high" in Vitamin K to no more than 3 servings a day.
    Spinach, fresh, boiled is considered high--eat no more than 1/2 a cup a day (1 serving= 1/2 cupr for cooked spinach).

    Raw spinach is considered moderately high--eat no more than 3 cups a day (3 servings)--serving size is 1 cup.

    Other foods to watch out for (no more than 1/2 a cup a day) that are "high" in Vitamin K include kale, fresh, boiled; turnip greens, frozen boiled; collards, fresh, boiled; swiss chard, fresh, boiled; Parsley, raw; mustard greens, fresh, boiled.

    When eaten raw, you can eat up to 3 cups a day of the above vegetables.

    Also, limit/avoid alcoholic beverages if possible.

    For your information--if you are not on any anti-clotting medication, I would not worry about Vitamin K.
