Vitamin k2 powder is essential for normal blood clotting and plays a key role in calcium absorption and bone formation. There are two main forms of vitamin K: phylloquin one (vitamin K1) and menaquinones (vitamins K2), whereas the latter is regarded as a better source of vitamin K.

In a typical western diet, the intake of vitamin K2 is often less when compared with the traditional Asian diet.
