4. The role of vitamin k3

It works as vitamin nutritional supplements. Vitamin K is essential for the synthesis of proenzyme (factor B) in the liver and is involved in the synthesis of coagulation factors VII, IX, and X, which maintain the physiological process of blood clotting in animals. Lack of vitamin K can cause the impaired synthesis of the above coagulation factors, affecting the coagulation process and causing bleeding. Vitamin K is also necessary for the vitamin K-dependent carboxylation system in the animal organism (mainly in tissues and organs such as the liver, bones, testes, skin, and kidneys) and is an indispensable factor in the synthesis of skeletal proteins (BGP). In addition, it plays an important role in the process of metabolism and oxidative phosphorylation of high-energy compounds, as well as in aspects of metabolism with other fat-soluble vitamins, and has the function of diuretic, enhancing the detoxification function of the liver, participating in the structure of membranes and lowering blood pressure.
