How much Vitamin K is in aronia berry juice and acerola cherry juice?

I am a diabetic and on warfarin for Factor V Leiden. I usually cannot drink orange juice because of its effect on my GERD, but I have found a juice that I can tolerate called "Fruit 2 day." The Strawberry Banana contains 2 ingredients, among other ingredients, that I am not sure about with the warfarin: Aronia berry juice from concentrate & acerola cherry juice from concentrate. Do you know if these two ingredients have any effect on warfarin?

Dr. Gourmet Says...

I have looked for information on the Vitamin K content in aronia and acerola berries and have come up with nothing. Sorry.

That said, juice may not be your best choice especially given your diabetes and GERD. The acidic nature may provoke acid reflux and the concentrated sugar can spike your blood sugar. It's best to get your servings of fruit as real fruit.
