Super K provides THREE kinds of vitamin K: vitamin K1 and two forms of K2, menaquinone-4 (MK-4) and menaquinone-7 (MK-7). Taking Super K everyday is a good way to make sure you’re getting enough of this essential nutrient for bone and vascular heath*.

Vitamin K helps maintain bone density by facilitating the incorporation of calcium into your bones.1 It also supports normal function of a protein called matrix Gla-protein (MGP).2 MGP helps regulate how calcium interacts with your arterial walls.3 So in addition to facilitating calcium incorporation into bone, vitamin K helps promote a healthy calcium balance in your arteries.
