98% Vitamin K2 (MK-7) Bulk Of ISO Factory
Vitamin K2 (MK-7)—also known as Menaquinone-7—is a highly bioactive, lipid-soluble form of vitamin K2 characterized by a seven-isoprene-unit side chain. This unique molecular structure gives it an exceptionally long half-life (up to 72 hours) in the human bloodstream compared to other vitamin K variants.
MK-7 is a homolog of Vitamin K2, primarily produced by bacteria and found in fermented foods such as natto. It is identified as the most bioactive cofactor in the carboxylation of Gla proteins. Human cells cannot produce MK-7 endogenously, making exogenous sources—including dietary supplements and functional foods—essential. This is why Vitamin K2 is often called the “platinum vitamin”.

We guarantee ≥98.0% purity (HPLC-verified) for pharmaceutical-grade, with ≥99.0% purity available for premium formulations. Every batch is tested for identity, purity, and quality parameters in accordance with USP standards.
What documentation do you provide with each order?
Every shipment includes a Certificate of Analysis (CoA), Method of Analysis (MOA), Material Safety Data Sheet (MSDS), and stability data.
What is your minimum order quantity (MOQ)?
For commercial manufacturers, our MOQ is 1 kg, with volume discounts available for larger commercial orders. For R&D, analytical research, and compounding pharmacy applications, we offer smaller quantities.
Is your Vitamin K2 (MK-7) API GMP-certified?
Yes. Our API is produced in facilities adhering to strict current Good Manufacturing Practices (cGMP) for pharmaceutical and nutraceutical ingredients, with full compliance with ICH Q7 guidelines. We maintain DMF filings with regulatory authorities.
What is the mechanism of action of Vitamin K2 (MK-7)?
MK-7 acts as an essential cofactor for the enzyme gamma-glutamyl carboxylase. It activates two key proteins through carboxylation: Matrix Gla Protein (MGP) in the vasculature—the most potent known inhibitor of vascular calcification—and Osteocalcin in bone tissue. This dual mechanism directs calcium away from arterial walls and into the bone matrix, preventing cardiovascular morbidity while supporting bone health.
What is the half-life of Vitamin K2 (MK-7)?
MK-7 has an exceptionally long half-life (up to 72 hours) in the human bloodstream compared to other vitamin K variants. This extended half-life enables once-daily dosing and sustained biological activity.
What is the difference between Vitamin K2 as MK-7 and MK-4?
MK-7 and MK-4 are both forms of vitamin K2, but they differ significantly:
MK-7 has a seven-isoprene unit side chain, giving it a longer half-life (up to 72 hours) and superior bioavailability compared to MK-4
MK-7 is the most bioactive form of vitamin K2
MK-7 is produced via bacterial fermentation and found in natto
MK-7 is the preferred form in modern nutraceutical and pharmaceutical formulations
What is the solubility and storage profile of Vitamin K2 (MK-7) API?
Vitamin K2 (MK-7) API is a light yellow to yellow crystalline solid that is lipid-soluble and practically insoluble in water. It should be stored protected from light, at -20°C, under argon. Shipping requires a cold chain (ice chest + ice pads).
Is Vitamin K2 (MK-7) FDA-approved?
Vitamin K2 (MK-7) is FDA-approved under Generally Recognized As Safe (GRAS) status as a dietary supplement. The FDA has issued a “No Question” GRAS Notification for Natural Vitamin K2 (MK-7). It is permitted for use in nutritional beverages in the United States. It is also permitted as a source of Vitamin K in the European Union.
Who are the primary manufacturers of Vitamin K2 (MK-7) API?
Key manufacturers include Kappa Bioscience AS (Norway—K2VITAL®), NattoPharma (Norway—MenaQ7®), DSM (Global), Synergia Life Sciences (India—MenaquinGold®), GF FERMENTECH (MediQ7®), and numerous manufacturers in China,na including Seebio Biotech and Richerpharm Technology.
What are the common side effects of Vitamin K2 (MK-7)?
Vitamin K2 (MK-7) is generally well-tolerated with no known toxicity at recommended doses. It is non-toxic and safe for long-term use. Patients taking coumarin anticoagulants (such as warfarin) should not take Vitamin K2 supplements without medical supervision.
What drug interactions should be considered?
Vitamin K2 (MK-7) is not suitable when taken simultaneously with coumarin anticoagulants. Patients should inform their healthcare provider about all medications they are taking, particularly blood thinners.
Can you supply Vitamin K2 (MK-7) API for compounding pharmacy applications?
