Vitamin K2 Explained: Why D3 Needs a Co-Pilot

Vitamin D3 is well known for supporting calcium absorption. Less well known is that absorbing more calcium isn't automatically useful on its own, calcium also needs to be directed to bone tissue rather than soft tissue. That's where Vitamin K2 comes in: it activates proteins involved in guiding calcium to where the body uses it.

Why they're paired

Because D3 increases calcium absorption and K2 supports how that calcium is used, many formulations, including this one, combine both rather than shipping D3 alone.

What the science supports

Vitamin D3 contributes to normal absorption and utilisation of calcium and phosphorus, and to normal function of the immune system. Vitamin K2 contributes to normal blood clotting and supports normal bone structure.
