  1. The main physiological function of vitamin K is to promote the production of prothrombin (coagulation factor II) in the liver, and it also regulates the formation of coagulation factors VII, IX and X. Lack of vitamin K, prolonged blood clotting time, bleeding can occur in severe cases. It has been found that there is a precursor of thrombin in the liver.
  2. The synthesis of this precursor does not require Vitamin K in the Chemicalbook. The physiological function of vitamin K is to convert this prothrombin precursor into thrombin. The difference between thrombin precursor and prothrombin has been clarified at the molecular level. The glutamic acid in the terminal amino acid residues of prothrombin is all γ-carboxyglutamate, while the prothrombin precursor is all glutamate.

  1. Natural vitamins include vitamin K1 and vitamin K2, which are derived from plant foods and produced by intestinal bacteria, respectively. They are fat-soluble and require bile to assist in absorption. The synthetic vitamins K3 and K4 are water-soluble and do not need bile to assist in absorption.
  2. Vitamin K is a necessary substance for the synthesis of coagulation Chemicalbook blood factors II, VII, IX, X, thereby promoting the coagulation process. When vitamin K is lacking, the synthesis of the above coagulation factors is impaired, affecting the coagulation process and causing bleeding. This product also has analgesic effect, and the mechanism of action may be mediated by opioid receptors and endogenous opioids
