Vitamin K2 is a fat-soluble vitamin, a derivative of naphthoquinone group with biological activity of phylloquinone. It is one of the indispensable important vitamins in the human body, and it plays a vital role in many aspects of health.

To understand vitamin K2, you must first understand vitamin K. Vitamin K is an active substance that can affect the synthesis of prothrombin and the blood coagulation process. Vitamin K can be divided into two categories, one is fat-soluble vitamins, namely vitamin K1 extracted from green plants and vitamins synthesized by intestinal bacteria K2, the other is water-soluble, that is, synthetic vitamin K3 and vitamin K4. Naturally occurring vitamin K is divided into two types according to its side chains: vitamin K1 and vitamin K2. Among them, vitamin K2 has high activity and medicinal value.

Whats the Functions of vitamin K2?

(1)Anti-arterial calcification and osteoarthritis

Anti-arterial calcification and osteoarthritis Vitamin K2 has a strong inhibitory effect on cartilage and vascular calcification, and can efficiently remove abnormal calcium plaques. Its biological activity depends on the level of vitamin K2 in the body. Studies have shown that osteoporosis, osteoarthritis, vascular sclerosis and other diseases all have vitamin K2 deficiency.

(2）Anti-Osteoporosis

Vitamin K2 has a much more significant anti-osteoporosis effect than vitamin K1, and has its unique two-way regulation anti-osteoporosis mechanism.

Promote bone mineralization: Osteocalcin can promote calcium salt deposition, increase bone mineralization rate, maintain normal bone calcification and crystal formation and cartilage mineralization rate, and directly reflect bone formation and bone reconstruction.

Promote bone formation: Vitamin K2 is a bone-specific gene transcription regulator, which induces the expression of osteoblast markers through steroid and heterogeneous receptors, enhances the accumulation of collagen, improves bone quality, and promotes bone formation.

Inhibition of bone resorption: Osteoclasts are the only cells capable of resorbing bone, creating an acidic environment through proton pumps to cause osteocalcin and cathepsin to dissolve bone matrix.

（3）Improve diabetes

Vitamin K2 can up-regulate insulin gene, promote islet β cells, release insulin, improve the body's metabolism, and help diabetic patients recover.

（4）Accelerated coagulation

Vitamin K2 is a natural fat-soluble vitamin. If there is a lack of vitamin K2 in the body, blood coagulation abnormalities may occur. At this time, vitamin K2 treatment can accelerate blood coagulation and maintain blood coagulation time.

 (5) Antitumor

Vitamin K2 negatively regulates tyrosine kinase and phosphatase activity related to cell carcinogenesis, and regulates regulatory factors related to cell proliferation, eventually leading to cell cycle arrest or cell death. Among them, vitamin K2 can prevent liver cirrhosis from progressing to liver cancer.
