Vitamin K2 (MK-7)

K2 directs calcium into bones and teeth while preventing its deposition in arteries and soft tissues, working synergistically with vitamin D3. The Rotterdam Heart Study found high K2 intake reduced cardiovascular mortality by 50% over 10 years. MK-7, derived from Japanese natto fermentation, has the longest half-life and greatest bioavailability of all K2 forms.
