Function of Product


Vitamin K2 is a form of vitamin K with biological activity. Its main role is to accelerate blood clotting and maintain blood clotting time. It can be used for the treatment of hemorrhagic disease caused by vitamin C deficiency, and also for the treatment and prevention of osteoporosis. First of all, vitamin K is involved in the process of blood clotting in the body. If a patient lacks vitamin K, he or she may experience coagulation dysfunction, which can lead to bleeding. Vitamin K also plays a role in bone, which can prevent and treat osteoporosis and play an adjuvant role in treatment. In addition, vitamin K also has a certain anti-tumor effect, can prevent liver cirrhosis into liver cancer. Therefore, vitamin K mainly has the function of promoting blood clotting, preventing osteoporosis, and preventing cancer.

Application of Product


In the past 40 years, especially in the last 20 years, due to the breakthrough in detection technology of serum vitamin K and vitamin K deficiency induced protein, numerous articles about infant hemorrhage caused by vitamin K deficiency have been reported around the world. It is believed that vitamin K deficiency is an important cause of infant hemorrhage disease and death worldwide. According to the national child mortality monitoring data in 1995, intracranial hemorrhage is the seventh leading cause of infant mortality in China, with a mortality rate of 77.4 per 100,000 infants. Vitamin K2 preparations are effective in restoring prothrombin to normal levels and controlling bleeding.


Some elderly people also have vitamin K2 lack, appear prothrombin long phenomenon; Prothrombin is also reduced when dicarboxycoumarin is used in excess. In the intravenous nutrition, antibiotics were added into the injection, and the anticoagulant vitamin K2 was synthesized in the intestine. But the conversion of water-soluble vitamin K3 derivatives to activated vitamin K is too slow to be effective. Vitamin Ka absorption is reduced when the biliary tract is obstructed, and vitamin K2 deficiency can also occur. Oral or transdigestive supplementation must be provided with bile salts. In some liver diseases, due to reduced coagulation factor synthesis due to dysfunction, vitamin K supplementation has no effect on coagulation, and direct vitamin K2 supplementation is required.



Different forms of vitamin K2


Vitamin K2 is needed to activate osteocalcin, a protein found in bones. Without vitamin K2, this protein and others dependent on vitamin K2 become inactive and thus unable to perform their biological functions.


According to Leon Schurgers, a world-renowned vitamin K2 researcher, the difference between vitamin K1 and vitamin K2 was clearly confirmed in the Rotterdam study published in 2004.


While the study focused on the effects of vitamins K1 and K2 on the heart (vitamin K1 had no effect at all), the researchers also looked at the types of food that provided each vitamin K.
