Green tea and Matcha products

Hi Team,

Does anyone have experience how Green Tea and Matcha products affected their INR?

I am about to try a new food called matcha soaked oats this week, but was wondering what People's experiences are?

Thank you

Green Tea has been on the list of foods that can affect INR. Matcha is a green tea product. Like many things, I think it is a drink that should be consumed in smaller amounts but not entirely avoided. I have personally never drunk it.......only because I doubt I would like it, not because I would be afraid of it. Try it and test your INR in a few days to see if it made a difference.

Good morning ... I haven't had Matcha since Japan (so that predates my mech valve), however from what I understand to have an influence on INR its either got to

have a high Vitamin K content
effect P450 (mitochondria enzymes)

So:

stuff all in there, as one would not normally see a tipping point into INR until vitamin K approaches 1mg in a day. The other good source is of course

which does not explicitly list matcha, but only has "green tea" (which we know to be different in concentration of leaf material).

It seems a touch sad to me that such a prized and historically significant beverage is being tipped on morning oats, but there it is

Ultimately (as I often say)"Test and know thyself"

Best Wishes

Matcha is an acquired taste (like coffee really), and like coffee varies in what person A vs person B likes in terms of which and what. There is not the equivalent of darker or lighter roasts, but there is the equivalent of "beans" and preparation.

My advice is: if you don't go to Japan, don't do it.
