Yes, as I see it there is little need to supplement Vitamin K.

K1 is found in leafy green veg, and converts to K2. And as Janet said, K2 is found in meat, cheese, eggs etc.

I would only contemplate supplementing Vitamin K if I had some serious illness, and I was under medical orders to do so.

And I take 10K units Vitamin D as well. I have done so for some years now with a huge improvement to my joint pain.
