Vitamin K2

1. Product Introduction

Vitamin K2, also known as menaquinone, is an essential fat-soluble vitamin with multiple physiological activities. Common natural vitamin K2 subtypes include MK-4, MK-6 and MK-7. Among them, MK-7 (Menaquinone-7) is mainly produced by microbial fermentation and artificial synthesis, and it can be biologically degraded into MK-4 in vivo.

Compared with Vitamin K1 and MK-4, MK-7 exhibits higher biological activity, superior bioavailability and longer half-life in the human body. It features excellent intestinal absorption efficiency and can maintain stable blood concentration for a long time, making it the most mainstream, high-efficiency and widely applied subtype of Vitamin K2 in global functional food and nutritional supplement markets.

We supply full-series vitamin raw materials including Vitamin K2 powder and oil formulations. Customized finished nutritional supplements with diversified dosage forms are supported to meet personalized market and production demands.

MENAQUINONE-7, MK-7 98% 

1. It has the effect of preventing and treating osteoporosis. MK-7 can increase bone density, improve bone quality, bone strength and collagen production. MK-7 can promote bone formation by stimulating osteoblast differentiation and upregulating bone marker gene expression.
2. MK-7 is associated with reducing cardiovascular and cerebrovascular calcification and coronary artery calcification.

2. Core Functions & Physiological Mechanism

2.1 Bone Health & Osteoporosis Prevention

Vitamin K2 MK-7 acts as an essential cofactor for bone metabolism. It can effectively stimulate osteoblast differentiation, up-regulate the expression of bone marker genes, and activate osteocalcin to promote bone collagen synthesis and bone mineralization. It significantly increases bone density, improves bone quality and bone strength, and effectively prevents and assists in the treatment of osteoporosis, bone loss and fracture risks, especially suitable for middle-aged and elderly people and menopausal women.

2.2 Cardiovascular & Cerebrovascular Protection

MK-7 is a key nutrient to inhibit vascular calcification. It activates Matrix Gla Protein (MGP) in blood vessels, which can chelate excess calcium deposited in vascular walls, effectively prevent coronary artery and systemic vascular calcification, reduce arterial stiffness, protect vascular elasticity, and lower the risk of cardiovascular and cerebrovascular diseases caused by calcium deposition and vascular aging.

2.3 Advantages of MK-7 Over Other Vitamin K Forms

Different from VK1 and MK-4, MK-7 has ultra-long half-life and excellent tissue affinity. It can be stably absorbed and utilized by bones and vascular tissues for a long time, realizing continuous physiological regulation. It is the most active and preferred vitamin K ingredient for high-end bone health and cardiovascular protection supplements in the global market.

FAQ

Q1: What is the difference between Vitamin K2 MK-7 and MK-4?

A: MK-7 has higher biological activity, longer half-life and better human absorption and utilization rate than MK-4. It can maintain long-term stable efficacy in the body and is the mainstream high-end K2 ingredient for bone and vascular health care.

Q2: What are the main functions of Vitamin K2 MK-7?

A: It mainly focuses on two core effects: promoting bone formation and increasing bone density to prevent osteoporosis; activating vascular protective protein to inhibit vascular calcium deposition and protect cardiovascular and cerebrovascular health.

Q3: What is the purity and safety of your product?

A: Our MK-7 purity is 99.16% with zero cis-isomer. All heavy metals, solvent residues and microbial indicators are far below the standard limits, which is food-grade safe and reliable.
