Vitamin K2 (MK-7) Oil 1% | Technical Guide
公開日: May 15, 2025
Vitamin K2 (MK-7) is a specialized formulation containing menaquinone-7, the most bioavailable and long-acting homologue in the vitamin K2 family. This oil-based preparation features a standardized 1% concentration, providing precise dosing capabilities for nutritional applications. MK-7 exhibits superior pharmacokinetic properties compared to other K vitamins, with a serum half-life of approximately 72 hours, enabling sustained biological activity. The molecular structure of MK-7 (2-methyl-1,4-naphthoquinone with a 7-isoprenyl unit side chain) confers optimal lipophilicity and enhanced tissue distribution.
