Why MediQ7

High-purity purification technology
Ultra-high concentrated MK7 (>96% MK7 conc. and 99.9% trans type) is a secret for high stability of MediQ7. Vitamin K2 stability is linked with purity.
According to the report (Molecules 2019,24,829), different purity profiles corresponded to different stability profiles, where high purity products generally showed the highest stability.

MediQ7 MK-7 is extracted using the proprietary purification process and maintains > 96% MK7 concentration and all-trans type 99.9%, the biologically active form.
Menaquinone-7 (MK-7) is classified into the Trans-type and the Cis-type. Trans-type Menaquione-7 is active in the body and has a linear structure. On the other hand, the Cis-type has a non-linear structure and cannot activate vitamin K2-dependent enzymes.

01

Trans-type and Cis-Type structure


→ Trans-type MK-7 , the active form of Vitamin K2

Cis type, a form of MK-7 that cannot be activated, is managed to be within 2% according to the United States Pharmacopoeia (USP).
MediQ7 guarantees more than 99.9% Trans-form MK-7.





The secret of high purity:
strain, supercritical CO₂ extraction, and refining technology
MediQ7 produces a high-purity Menaquinone-7 using proprietary fermentation technology, supercritical extraction, and purification technology using patented strains.

MediQ7 is an ultra-high purity vitamin K2 MK-7 made with supercritical dioxide extraction technology that is safe for the human body, fractionation technology that concentrates and refines targeting substances, and crystallization technology that separates products with high purity.

GF Fermentech's proprietary refining technology

GF Fermentech is a company specializing in fermentation and refining for more than 20 years and possesses advanced technology.
Materials made based on natural or fermentation are mixed with many substances other than active ingredients, and these are very difficult to separate and refine with ultra-high purity.

03

Supercritical carbon dioxide (CO2) extraction method

Supercritical CO2 extraction is a method that converts carbon dioxide, which is harmless to the human body, into a supercritical fluid state at high pressure, and extracts fragrances, pigments, oils, fats, and functional substances from products without denaturation.
Since supercritical CO2 extraction is chemically stable, the critical temperature is low to prevent deterioration of the extracted product, and CO2 is vaporized in lowered critical points, such as at room temperature and atmospheric pressure.

Therefore, MediQ7 is a product extracted without using chemical compounds, and it is a safe, stable and high-purity product made with over 20 years of refining technology.
