Vitamin K2 for Bone Health

Vitamin K2 plays a critical role in bone health by activating osteocalcin, a protein essential for binding calcium to the bone matrix. This activation enhances bone mineral density and strength, thereby lowering the risk of fractures and osteoporosis. Research indicates that maintaining adequate vitamin K2 levels is particularly beneficial for bone maintenance in postmenopausal women and older adults.¹

Vitamin K2 to Support Cardiovascular Health

It also supports cardiovascular health by activating matrix Gla-protein (MGP), a key protein involved in regulating calcium balance in the blood vessels. This process helps maintain arterial flexibility by limiting the inappropriate deposition of calcium in the artery walls, which is associated with arterial stiffness and cardiovascular risk.²

Vitamin K2 to Support Blood Clotting

While vitamin K1 is more commonly known for its role in blood clotting, vitamin K2 also contributes to this important function. It helps activate clotting proteins, ensuring that the blood can properly coagulate when needed. However, vitamin K2’s role in blood clotting is secondary to its effects on bone and cardiovascular health.³

Can Vitamin K2 Help Strengthen Teeth?

Vitamin K2 supports dental health by contributing to the proper use of calcium in the body. Working together with vitamin D, it helps ensure that calcium is directed to the bones and teeth, where it is needed most. This process helps maintain strong teeth and bones, and emerging research suggests it may also play a role in supporting overall oral health.⁴ ⁵
