However, given that typical western diets contain minimal amounts of vitamin k2, it is likely that deficiencies exist in many populations.

Humans can partly convert vitamin k1 to k2 in the body, but the conversion process is inefficient. The combination of vitamin k and calcium could reduce risk on post-menopausal bone and simultaneously prevent vascular calcification, thereby aiding the beneficial effects of calcium in bone and preventing the negatively associated vascular effects of supplemental calcium intake.
