Introduction of Product



In 1929, Dam discovered that there are two kinds of vitamin K in nature, K1 and K2, both of which are naphthoquinones. Pure vitamin K2 powder is a naturally occurring vitamin containing the basic structure of methyl naphthoquinone and has anti-bleeding effects. It is insoluble in water, soluble in organic solvents and vegetable oils at room temperature, and is heat resistant, but easily destroyed by light. Can promote liver synthesis of prothrombin, regulate coagulation factor Ⅶ, and, and synthesis, thereby accelerating blood coagulation.
