freal said:I read somewhere that Ray Peat says that liver has vitamin K. I cannot find about that anywhere on the internet, how much of it does liver have, according to Ray PEat. K2 or K1?
SourceRay Peat said:The other vitamins in liver, including vitamin K, function very closely with vitamin E, and the stably stored forms of vitamin E are likely to be a good approximation for our needs.
SourceRay Peat said:For vitamins, especially K, occasional liver can be helpful.
Mittir said:I did ask Ray Peat about liver's vitamin K content. His reply is in " Email Advice" section.
He made extract himself and there were few mili grams per Kilo.
But i have also read other sources they still claim liver is not a rich source of vitamin K.
Even people like Chris Masterjohn thinks liver does not have lot of vitamin K.
But he did not measure himself,he is just speculating.
Mittir said:I just got a reply from Dr Peat. I asked him about the amount of vitamin K in liver. Here is his reply
Ray Peat said:I made extracts myself, and there was a lot of it, but I didn't measure it exactly, just a few milligrams per kilo.

lazz said:how much vitamin E ,A and k2 is recommended daily??
vit K2 (mk4) is "factor X" this is how Weston Price named this vitamin.. Is found especially in grass fed animal products. As you can see goose liver - grass fed is very good source of vitK2, then good quality cheeses Brie, Gouda etc.. Then free range eggs etc.. Btw Peat don't have much idea about difference between vit K1-k2. I'm sure he had no idea about mk7 from fermented soy product natto etc.. But it is understandable. Nobody knows everything in depth..mayweatherking said:
There are a couple of therapeutic uses of supplemental vitamin K2. To maintain health the vitamin K2 you get from liver and other foods is probably more than enough.mayweatherking said:post 105867Giraffe said:
do you think that is enough vitamin K to offset aspirin or is it enough in general? i'm doing 1oz of beef liver a day and taking 81mg of aspirin with every meal.
