Vitamin K2 plays a crucial role in regulating calcium distribution in the body. It activates proteins that help direct calcium to bones and teeth while preventing its buildup in soft tissues like blood vessels and kidneys. This makes it essential for maintaining strong bones and supporting cardiovascular health.

It is widely used in dietary supplements aimed at improving bone density and reducing the risk of osteoporosis, especially in older adults. Research also suggests that adequate levels of Vitamin K2 may lower the risk of arterial stiffness, supporting heart health.

In clinical settings, it has been studied for its potential to improve outcomes in patients with bone or cardiovascular conditions. Additionally, Vitamin K2 is used in some oral care products due to its role in promoting dental health by supporting mineralization of teeth.

Emerging studies are exploring its role in metabolic health and inflammation, showing promise in managing conditions like insulin resistance and fatty liver disease.
