Kind of a misleading article???
The liver takes in almost all and does not convert it to k2 it is primarily used in production of clotting factors. Primarily factor X but it also effect’s factor 11 so a person taking one of the newer anti coagulants can start having problems if supplementing with higher doses of K1. The normal? Amount of V-K received from diet can be over come by these drugs but higher dose supplementing with K1 would be contraindicated.
The remainder of K1 that makes into the intestines gets converted by the bacteria in the intestines where it is then converted to K2.
Dug around and found this article that gives a real good account on which one of the K vitamins does what.http://www.nbihealth.com/t-mk7-hip-fractures.aspx
Then of course we have wiki but read the disclaimer at the beginning some of it is a little off base!http://en.wikipedia.org/wiki/Vitamin_K2
If your interested in Factor X this gets techy but shows what happens if you don’t get enough! http://emedicine.medscape.com/article/209867-overview
