Vitamin D helps the body absorb calcium from the diet.
Vitamin K contributes to the maintenance of normal bones and to normal blood clotting.Including vitamin K2 alongside vitamin D reflects how these nutrients work in the body’s normal physiology, particularly in relation to bone health.
Vitamin K2 helps activate proteins involved in directing calcium to where it is needed, such as the bones, as part of normal bone maintenance. This is why vitamin D and vitamin K are often considered together in supplement formulations designed to support overall bone health.
This formula provides vitamin K2 in a stable, bioavailable form to complement vitamin D intake within safe, regulated levels.
