【Product Introduction】

Vitamin K2 is a class of fat-soluble vitamins with a menaquinone structure, and an important member of the vitamin K family. It is mainly synthesized by intestinal flora or obtained from fermented foods. Its core function is to participate in the regulation of calcium metabolism in the body. By activating specific proteins (such as osteocalcin and matrix Gla protein), it promotes the deposition of calcium in bones and inhibits its abnormal deposition in blood vessel walls, which is of great significance to bone health and cardiovascular health.

【Appearance】

This product is usually a yellow to orange-yellow crystalline powder or oily liquid (slightly different depending on the dosage form and purity), with a slight characteristic odor, and has good stability under dark and sealed conditions.

【Specifications】

Common specifications are divided by different subtypes (such as MK-4, MK-7, etc.) 

• MK-7 (menaquinone-7): 0.2%~2%（2000~20000ppm）（HPLC）

• MK-4 (menaquinone-4): 95%~98%（HPLC）

(Note: Specific subtypes and raw materials with different purities can be provided according to customer needs to meet the application requirements of different fields such as food and health products)

【Product Features】

1. Subtype specificity: Different subtypes of vitamin K2 (such as MK-4, MK-7) have differences in in vivo half-life, bioavailability, etc. Among them, MK-7 is widely used in health products due to its long half-life and longer-lasting effect.

2. High purity and stability: Prepared by advanced extraction or synthesis processes, the purity can reach more than 95%. Moreover, technologies such as microencapsulation can improve its sensitivity to light, heat and oxygen, and enhance stability during storage and processing.

3. Targeted regulation function: It specifically acts on the skeletal and vascular systems, which can not only promote osteoblast activity and increase bone density, but also inhibit vascular calcification. It is a key nutrient connecting bone health and cardiovascular health.

4. Good compatibility: Powdered raw materials can be synergistically compatible with other nutrients (such as calcium, vitamin D), while oily dosage forms are suitable for soft capsules and other preparations, with good compatibility in various formulas.

【Product Applications】

1. Health food field: As a core raw material, it is added to health foods such as compressed candies, capsules, and soft capsules, focusing on functions such as "bone health" and "cardiovascular maintenance", suitable for middle-aged and elderly people, high-risk groups of osteoporosis, etc.

2. Nutritional supplement field: It is often compounded with calcium and vitamin D3 to make compound nutritional supplements, which enhance the absorption and utilization of calcium through synergistic effects and strengthen bone health effects.

3. Functional food field: It can be added to functional foods such as dairy products and cereal products, such as high-calcium milk powder and nutritional cereals, to endow ordinary foods with nutritional fortification functions related to bone health.

4. Pharmaceutical raw material field: It is used as a raw material in some auxiliary treatment products for osteoporosis and vascular calcification, providing support for the research and development of related drugs (must meet the standards of pharmaceutical-grade raw materials).
