Hi Beverly,

Green tea can affect INR readings when a person is taking warfarin. This combination usually increases INR, making patients more likely to bleed. This does not mean that you cannot drink green tea while on warfarin therapy, but it is important to keep your green tea intake consistant- don't drink a lot one day and then not drink it for awhile.

Thanks for your question!

I believe your answer is incorrect. Green tea typically will DECREASE ones inr although one would have to drink a lot if green tea to make it decrease enough for concern.


Here's just one link - http://www.heartpoint.com/coumadin.html


What foods are high in Vitamin K?

* Kale, spinach, and many green leafy vegetables.
* Broccoli, cauliflower, and brussel sprouts.
* Green tea

 

A google search with "green tea" & "INR" will give many links.

Green tea does NOT increase your INR.   One cup of green tea has 0.03mcg of vitamin K per 3.5 fluid ounces.  If anything, drinking too much green tea lowers your INR.  Please check facts before spreading false information.  When it comes to clotting disorders and issues I find so many people spreading false information, which in turn causes many problems for people suffering from these disorders/conditions.
