Best Fit Profiles
- vitamin D protocols
- bone and artery support stacks
Bone-vascular calcium balance
Vitamin K2 (MK-7)
MK-7 reliably improves vitamin K status biomarkers, while BMD and fracture endpoints remain mixed across trials.
Evidence Level B
Evidence and Risk Labels
Evidence A/B/C reflects research maturity, and risk levels reflect monitoring needs. These labels support comparison, not diagnosis or treatment decisions.

- Effect Size
- Consistent biomarker improvement with variable hard-outcome signal
- Safety
- Low Risk
Can interact with vitamin K-antagonist anticoagulants.
Research Dosing
This reflects common ranges and protocols used in published studies, not personal medical advice.
- Typical Daily Dose
- 90-200 mcg (MK-7)
- Timing
- Daily with meals containing fat
- Protocol Duration in Studies
- 12+ weeks with ongoing maintenance
Often paired with vitamin D3 to support calcium direction toward bone and away from vascular tissue.
