Vitamin K and osteoporosis: Myth or reality?

Vitamin K is necessary for improving bone health.  Vitamin K is found in plants and green vegetables.  If you decide to take dietary supplements, I would suggest you consider MegaQuinone K2-7.


Palermo A, et al.

This study was focused on determining the effect of Vitamin K (plasma levels, dietary intake, and oral supplementation) on bone health with specific emphasis in bone remodeling, mineral density and fragility fractures. Despite multiple observational and interventional studies on the association of Vitamin K and bone metabolism, the results were conflicting and unclear.

  • Vitamin K is a liposoluble vitamin.
  • The predominant dietary form, phylloquinone or Vitamin K1, is found in plants and green vegetables.
  • Menaquinone or Vitamin K2 is endogenously synthesized by intestinal bacteria and includes several subtypes that differ in side chain length.
  • Apart from its set role in blood clotting, several studies now support a critical function of Vitamin K in improving bone health.
  • Vitamin K is necessary for osteocalcin carboxylation which in turn regulates bone mineral accretion.
  • The findings reported its probable role in promoting the transition of osteoblasts to osteocytes and also limiting the process of osteoclastogenesis.
