Among them, vitamin K2 (MK-7) is the most unique in the vitamin K2 family. It has been shown to have the highest bioavailability and a long half-life in the blood after oral ingestion, thus being able to exert its benefits over a longer time cycle.

Product Description
Vitamin K2, also known as menaquinone 7, is a fat-soluble vitamin, commonly referred to as MK. It is important for the health of bone and cardiovascular. Vitamin K2 is generally subdivided into the short-chain menaquinones (with MK-4 as the most important member) and the long-chain menaquinones, of which MK-7, MK-8 and MK-9 are nutritionally the most recognized. The activity of vitamin K2 is related to the length of the side chain, the longer the side chain, the better the absorption, the higher the biological activity, and the longer the presence in the blood.
Difference Between Vitamin K2 MK-4 and Vitamin K2 MK-7
Vitamin K2 contributes to bone and cardiovascular health. Therefore, two vitamin K2 homologues, menaquinone-4 (MK-4) and menaquinone-7 (MK-7), have been used as nutrients by the food industry and as nutritional supplements to support bone and cardiovascular health.

Manufacturing Technique
Function
1.Vitamin K2 MK7 is being used to cure haemorrhage caused by VK2 deficiency; promotes the formation of thrombin,accelerates blood clotting, maintains proper clotting time;
2. Vitamin K2 MK7 is being used to treat the degenerative bone disease osteoporosis. VK2 produces a specific protein known as osteocalcin which can bind calcium, therefore to increase the density of bones and to prevent fracture.
3. Vitamin K2 MK7 can prevent hepatocellular carcinoma in women with viral cirrhosis.
4. Vitamin K2 MK7 has function of diuresis, promotes the detoxifcation of liver and lowering the blood pressure.
Application
Health food: calcium supplement, osteoporosis prevention, etc.
Nutritional supplements and food additives: (supplemental calcium, etc.) Beverages (sports drinks )
