Vitamin K is vital for bone and vascular health, but it’s difficult to absorb from our diet. We offer multiple versions of this essential vitamin. Let’s compare our most popular formulas to see which best meets your needs.

Vitamin K and K blends

Our Super K formula has three forms of K: vitamin K1 as well as two forms of K2. The two K2 forms (MK-4 and MK-7) have complementary nutritional properties — MK-4 is rapidly absorbed, and MK-7 absorbs more slowly. If you only need a little MK-7, our Low Dose Vitamin K2 includes 45 mcg of K.
