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.

I've tried several different omegas and this is by far the best I'm not waking up with pain in my back and my mood is way better

This product is great...well worth the money. It works great for my arthritic knee, and for my head and heart, along with all the other good things we do to take care of ourselves.
