Involved in activating clotting proteins

Vitamin K2 (menaquinone) likewise takes part in activating vitamin K-dependent clotting proteins, but source and half-life differ among MK-4/MK-7/MK-9. Supplements should name the specific MK form and micrograms. Understand the use first as K-dependent protein activation, then read studies by form.
