Product education

Vitamin K2: Long-Lasting Bone and Vascular Support*

This high-quality supplement provides natural Vitamin K2 in the form of menaquinone-7 (MK-7), which has the longest half-life in the body compared to other forms of Vitamin K. Recent research has highlighted several important functions for vitamin K beyond its traditional role in blood coagulation, including significant benefits for bone health and vascular function. This soy-free formula provides a clean, effective way to supplement this crucial nutrient.*

How It Works: Directing Calcium to Where It’s Needed

Vitamin K2 plays a critical role in calcium metabolism, acting as a “director” to ensure calcium is deposited in the right places.

Supporting Bone Health
Vitamin K2 is required to activate osteocalcin, a protein that binds calcium to the bone matrix. Proper activation of osteocalcin is essential for building and maintaining strong, healthy bones.*

Promoting Vascular Function
This vitamin also activates another protein called matrix Gla-protein (MGP), which helps to prevent calcium from accumulating in soft tissues like arteries. By supporting arterial flexibility and health, Vitamin K2 is a key nutrient for cardiovascular wellness.*
