The Science Behind Vitamin K2

Calcium Balance and Bone Health

Vitamin K2 plays a critical role in activating osteocalcin, a protein that binds calcium to bone tissue. Without adequate K2, calcium may not be properly integrated into bones, increasing the risk of bone fragility. Supplementation ensures that calcium strengthens your bones where it belongs.

Arterial and Cardiovascular Protection

Calcium is vital for health, but when it accumulates in the wrong places, such as arteries, it can harden and impair blood flow. Vitamin K2 activates matrix Gla-protein (MGP), a protective factor that prevents calcium from depositing in artery walls. This helps maintain arterial flexibility and supports long-term cardiovascular wellness.

Synergy with Vitamin D3

Vitamin D3 increases calcium absorption, but Vitamin K2 ensures it’s delivered to the right tissues. Taking K2 alongside Vitamin D provides the most effective strategy for supporting both bone strength and heart health.
