Vitamin K2(MK7)
Vitamin K2 MK-7 (Menaquinone-7) is the most bioactive subtype of Vitamin K2, produced via liquid deep fermentation of pure Bacillus subtilis strains without chemical synthesis. Our MK7 series strictly controls ≥99% all-trans active isomer with ultra-long blood half-life, delivering dual benefits for bone mineral density and vascular wall health. Focusherb supplies full industrial grades: 0.1%/0.2%/1% standard powder, 1500ppm MCT soluble oil, and 98% high-purity crystal. Microcapsule and liposomal anti-oxidation modifications are available to solve MK7 photo-degradation defects. All batches are verified by HPLC fluorescence detection, complying with USP, FDA GRAS and EU Novel Food standards.
Our MK7 supports bulk wholesale, D3/calcium compound pre-blend OEM, and full private label customization. It is the core raw material for mainstream D3+K2 bone supplements, vascular wellness tablets, elderly bone care and maternal adolescent nutrition formulas.

Bacillus Subtilis Strain Fermentation & Low-Temp Purification Process
We adopt proprietary pure Bacillus subtilis liquid deep fermentation technology, completely eliminating toxic byproducts from chemical synthesis routes. The full production line operates in a light-shielded GMP clean workshop, using low-temperature supercritical CO2 extraction and macroporous resin gradient chromatography to remove inactive cis-MK7 impurities. Optional microcapsule coating solves the core industry pain point of MK7 photo-oxidation and instability. Zero organic solvent residue, fully matching global clean label brand audit requirements.

What’s Vitamin K2(MK7)?
Vitamin K2 (menaquinones) is a slightly lipid soluble vitamin produced by the helpful microbe of intestines. It is a derivative of naphthoquinone and has similar biological activities as phylloquinone. More importantly, it is one of the indispensable and important vitamins in human body.
There are total 14 forms of vitamin K2 (usually noted as MK), which are MK-4, MK-7, MK-8, MK-9, etc. Among them, the synthetic MK-4 and natural MK-7 are the most common forms of vitamin K2. Both of them play important roles in bone and cardiovascular health.
The bioactivities of vitamin K2 are related to the length of its side chain. The longer the side chain is, the higher the biological activities are. Vitamin K2 with long side chain is also easier to be absorbed and can exists in the blood for a longer time. Vitamin k2-7 (MK-7) is the most unique in the vitamin K2 family and has been proved to have the highest bioavailability. It has a long half-life in the blood after oral intake, thus it can play its benefits for a long period of time.
