The main forms are MK-4 and MK-7. MK-7 is widely used in dietary supplements due to its higher bioavailability and longer half-life in the bloodstream.
We supply Vitamin K2 MK-7 pure and standardized powder, available in standard concentrations of 0.2%, 1.0%, and 1.5% purity.
MK-4 and MK-7 differ primarily in their chemical side-chain structure, absorption metabolism, and retention duration in the body. MK-7 stays active significantly longer, making it the preferred choice for sustained nutritional support.
We provide complete documentation, including a Certificate of Analysis (COA), HPLC test reports, MSDS, and relevant technical data sheets upon request.
MK-7 activates osteocalcin to direct calcium directly into the bones, while also activating matrix Gla protein (MGP) to prevent calcium accumulation in arteries and soft tissues.
Sample orders start from 1kg in aluminum foil bags, and commercial bulk quantities are packed in standard 10kg to 25kg fiber drums with double food-grade inner plastic lining.
