Vitamin K1 (phylloquinone)

Vitamin K is an essential micronutrient, sometimes referred to as a coagulative vitamin. Vitamin K includes two natural forms - vitamin K1 (phylloquinone) and vitamin K2 (menaquinone).

Maybe you are interested in a function and behaviour of vitamin K. These vitamins act as coenzymes in the synthesis of some biologically active proteins involved in blood clotting. They are also necessary for the bone and tooth strength and also used in other important biological processes (1).

Phylloquinone and menaquinone are responsible for body regulation of calcium. Vitamin K1 is processed by liver and then it is followed by protein-calcium binding.

Vitamin K2 is responsible for activation of proteins, which are responsible for regulation of calcium and its secretion.

There is evidence that vitamin K contributes to normal blood clotting and to the maintenance of normal bones. 5 servings of Mana or Mana Drink contains 75 µg of vitamin K1 (phylloquinone).
