Vitamin K2 helps to build calcium in the bones and is essential for bone health.  Indirectly, via osteocalcin, it facilitates binding of calcium to crystals of hydroxyapatite that form bone matrix.

Vitamin D3 is necessary for resorption of calcium.

Vitamin K2 with vitamin D3:

  • accelerate the function of cells that build bones - osteoblasts
  • at the same time reduce fusion of cells that break down bones - osteoclasts, which together generate synergistic effect.
