The most useful measures are shown at the top of the list. In addition to total vitamin K2, total vitamin K includes the small amount of vitamin K1 that is present in some of these foods. MK-4 is the form that plays a specific role in regulating gene expression. MK-4 and MK-7 are the two forms that have been studied well and shown to support the activation of vitamin K-dependent proteins produced outside the liver.
