Vitamin K2 

Vitamin K2 by Douglas Laboratories supplies a significant amount of biologically active vitamin K2 in the form of menaquinone-7 (MK-7). 


  • Bone formation support
  • Support for healthy blood vessels

Functions and Mechanism of Action

Vitamin K functions as a cofactor and enhances bone formation by carboxylation of osteocalcin. This enables osteocalcin to bind to calcium and promote healthy bone mineralization. Vitamin K, or menaquinone, includes a group of compounds that contain a central ring structure with varying side chains.

These differing side chains account for variations in absorption, bioavailability, transport, and tissue distribution.

The most common menaquinones are menaquinone–4 (MK–4) and menaquinone–7 (MK–7). Studies indicate that MK–7 concentrates in extra–hepatic tissues, including vascular tissues, and has a longer half–life compared to the MK-4 form.

In addition, vitamin K supports healthy blood vessels by functioning as a cofactor in the production of blood coagulation factors and vessel walls.
