How it works
Vitamin K2 is clinically supported for its role in bone mineral density maintenance and cardiovascular health. It activates proteins that direct calcium into bones and away from arterial walls, potentially reducing vascular calcification.
Acts as a cofactor for the carboxylation of osteocalcin and Matrix Gla Protein (MGP), regulating calcium distribution in the body.
Safety
- Interacts with Vitamin K antagonists (e.g., Warfarin); consult a doctor.
- Generally safe and well-tolerated at standard doses.
