Best Vitamin K for Dental

Clinical dose: 90–200 mcg
Why Vitamin K for Dental
Vitamin K plays a supporting role in dental. K1 (phylloquinone) primarily supports blood clotting, while K2 (menaquinones) directs calcium into bones and teeth rather than arteries. Among K2 forms, MK-7 has a much longer half-life (~96 hours vs 1–8 hours for MK-4), making it far more effective for bone density and cardiovascular health at lower doses.
What dose to look for
Clinical studies typically use 90–200 mcg of vitamin k. MK-7 supplements typically provide 100–200 mcg. Supplements that fall short of this threshold are unlikely to match what clinical trials achieved.
