Green tea and Matcha products

[tommyboy14]

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

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.

I drink between 3 and 5 cups of green tea per day. I've never noticed an impact on my INR

I recall learning in pharmacy school circa 1981 when studying warfarin that green tea - not mentioning matcha - has a very high amount of vitamin K, and a few years later information came out that it was in reference to the tea LEAVES themselves, not the brewed product, which contained a very small, practically insignificant, amount. Maybe matcha has more in the brew - I haven't seen any info on that. But I've been drinking Kirkland brand of Sencha/Matcha green tea and have not discerned any effect.

Hi

and a few years later information came out that it was in reference to the tea LEAVES themselves, not the brewed product, which contained a very small, practically insignificant, amount.

indeed ... and sometimes the assayer is a bit oblivious to the actual use. To the point:

Maybe matcha has more in the brew - I haven't seen any info on that.

the key to understanding Matcha (syllables go MA-CHA there is no T in there in Japanese) 抹茶 is found in the kanji (which provide in and of themselves the etymology of the word). The second character is just "tea", while the first has the hint in it

https://en.wiktionary.org/wiki/抹#Japanese

So its powered (by desiccation then grinding) actual tea leaves ... you can see the brush used in mixing in my picture ... its made from a piece of bamboo and carved to leave the 'bristles' in place.

Google provides a very nice summary (in my opinion)

To prepare matcha, you can follow these steps:

1. 1. Sift the matcha
   Sift the matcha powder into a bowl to remove clumps and ensure it mixes well.
   
   
2. 2. Heat water
   Use soft water, like spring or filtered water, that's heated to around 176°F (80°C).
   
   
3. 3. Add matcha to water
   You can add a few drops of hot water to the matcha powder and mix into a paste with a spoon. Then, add more hot water to the paste and stir. The ratio of matcha to water is usually 1 teaspoon to 6 ounces.
   
   
4. 4. Whisk
   Use a matcha whisk (chasen) to whisk the matcha and water together in a "W" or "M" pattern. Whisk quickly to create a froth.
   
   
5. 5. Drink
   Your matcha is ready to drink.

Never had matcha, (saporo i do know ) ; green tea i take 4 cups a day, it does not seem to create any problems for my inr; maybe it just helps to keep it more stable; because when i dont drink it for few days cause of travels inr tends to go up, but it may be just a coincidence.

I drink green tea often and matcha occasionally with no effect.
