Vitamin K is found in two primary forms: Vitamin K1 (phylloquinone) and Vitamin K2 (menaquinone). There are a few different menquinones such as menaquinone 4 and menaquinone 7. The main difference between these forms is that K2 as menaquinone 7 is absorbed at a much higher rate than K1 and remains in the body 36 times longer (allowing it to move beyond the liver into other tissues); whereas K1 is primarily utilized by the liver to make blood clotting factors. In addition to other roles, Vitamin K2 (menaquinone-7) is essential for healthy, strong bones and for supporting arterial health
