I am driven to not only get some Mk7 but also some of the thorn’s Liquid K2 mk4! Also because of the 90% reduction in blood calcification in 4 months of the lady I spoke of in this same thread, who used the Thorn's!
This Guy Stephan Guyenet has some interesting things to say on K2.
He decided to try the thorns Brand k2 mk4 liquid and here he did an update.
Finally, you can also buy K2 supplements. The best one is butter oil, the very same stuff Price used to treat his patients. I have used this one personally, and I noticed positive effects on my skin overnight. Thorne research makes a synthetic liquid K2 MK-4 supplement that is easy to dose drop-wise to get natural amounts of it. Other K2 MK-4 supplements are much more concentrated than what you could get from food so I recommend avoiding them. I am generally against supplements, but I've ordered the Thorne product for a little self-experimentation. I want to see if it has the same effect on my skin as the butter oil (update- it does).
