The importance of vitamin D for bone health has been recognised since it helped eliminate rickets in the 1930s. Vitamin D is an important component for good bone health as it has been shown to:

• Improve intestinal calcium absorption
• Contribute to normal calcium blood levels
• Improve bone calcium mineralisation

However, supplementing with vitamin D and calcium alone may not be sufficient for ensuring healthy bones.

Calcium is important for bones – however, it needs both vitamin D and K in order for it to be effective. Even though vitamin D helps the body absorb calcium, it is vitamin K2 that helps incorporate calcium into the bone matrix.

By activating the bone‐building protein osteocalcin, vitamin K2 binds calcium to the bone mineral matrix.
