What Does Vitamin K2 MK-4 Do?

Vitamin K2 MK-4 activates osteocalcin and matrix Gla-protein, which helps steer calcium toward bones for structure and supports arterial health by trimming calcium buildup in vessels.

These actions align with EFSA-inspired ideas of nutrient function, emphasising normal calcium use and vascular flexibility as part of everyday physiological processes.
