There are more fatty animal products, butter can be a good source, egg yolks are decent, I can see if I can find a list, I think odd organ meats like brains do as well, but does seem that the amount in the animal product depends on how the animal is raised, so cows eating grass, chickens finding bugs and plants and stuff. I've seen speculation that seafood is a good source as well, but again, it's probably when the whole fish is consumed.http://www.westonaprice.org/On-the-T...lved.html#fig4
Animal products actually have MK4, not MK7... MK7 is a result of fermentation, so cheese will have a mix of MK4 directly from the milk and MK7 from the fermentation in the cheese-making process. Natto, a strongly flavored fermented soy product has tons and tons of MK7, but like the link said, it's not preferentially passed on the way MK4 is.
That said, for a variety of reasons we supplement.
There's a liquid supp, Thorne brand K2, that's 1000mcg per drop, which is a robust dose. And Carlson has a 5-mg (5000mcg, just so it doesn't look like I did a typo) that's a really high dose and most people wouldn't need that much, but the capsules can be opened if someone wanted just part.
