Vitamin K2 Natto Extract


Organic Natto Powder

Product Description

Product Introduction

In 1929, Dam discovered that there are two kinds of vitamin K in nature, K1 and K2, both of which are naphthoquinones. Natto Extract (vitamin k2 mk7 powder) is a naturally occurring vitamin containing the basic structure of methyl naphthoquinone and has anti-bleeding effects. vitamin k2 mk7 powder is insoluble in water, soluble in organic solvents and vegetable oils at room temperature, and is heat resistant, but easily destroyed by light. Natto Extract Can promote liver synthesis of prothrombin, regulate coagulation factor Ⅶ, and, and synthesis, thereby accelerating blood coagulation.

The Function of Vitamin K2 MK7 Powder

Natto Extract 3 epoxides are metabolites of vitamin K in the liver. They are produced in large quantities in the liver of animals treated with warfarin. The anticoagulant effect of Chemicalbook is to inhibit the reductase that reduces the epoxide to vitamin K, thus blocking the interconversion of vitamin K and its epoxide in the body and halting the activity of vitamin K in the synthesis of thrombin.


The Method of Vitamin K2 MK7 Powder


Natto Extract Powder in alkali and light are unstable, easy to decompose, and heat, acid resistance. The stability of vitamin k2 mk7 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.
