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.

Function of Product


1. Vitamin K2 is very beneficial because it ensures that calcium does not accumulate in your arteries, but instead is delivered to your bones and teeth, thereby reducing your risk of atherosclerosis and kidney disease, and providing support for your hormonal health.

2. Vitamin K2 plays an important role in balancing testosterone production in men and women, reducing the risk of low testosterone levels in men and the risk of polycystic ovary syndrome in women.

3. Vitamin K2 also helps to reduce inflammation and improve insulin sensitivity, and can also be used as a cofactor of vitamin D and calcium to support bone health.

4. Vitamin K2 MK-4 is found in animal foods such as organic egg yolks, dark chicken and foie gras. The most effective form of MK-7 is found in fermented foods such as natto and in soft and hard cheeses such as Brie and Goude.



The Method of extracting vitamin K2 powder


Vitamin Κ2 in alkali and light are unstable, easy to decompose, and heat, acid resistance. The stability of vitamin Κ2 powder in the compound preparation was increased by microencapsulation technique. Microencapsulated membrane is a polymer material, and vitamin Κ2 is a fat-soluble vitamin, the extraction of vitamin 2 must use organic solvent, but the organic solvent can not dissolve the polymer encapsulated membrane, coupled with the instability of vitamin 2, resulting in the content of vitamin E 2 determination is very difficult; Therefore, none of the methods reported in the literature can determine the vitamin embedded in microcapsules Κ2.
