*Vitamin K includes a group of compounds that contain a central ring structure with varying side chains
These differing side chains account for variations in absorption, bioavailability, transport and tissue distribution
Vitamin K1, phylloquinone, is the most common form and is found in plants and green vegetables
The vitamin K2 family, menaquinones, are less common and are found in meats, eggs, some cheeses, and fermented food, such as Japanese natto
The most common menaquinones are menaquinone–4 (MK–4) and menaquinone–7 (MK–7)
Studies indicate that vitamin K1 and MK–4 are primarily concentrated in the liver, while MK–7 concentrates in extra–hepatic tissues, including vascular tissues, and has a longer half–life. Vitamin K enhances bone formation by carboxylating osteocalcin. This enables osteocalcin to bind to calcium and promote healthy bone mineralization
Adequate intake of vitamin K1 and K2 may be especially important for optimal carboxylation in aging individuals, as indicated by a recent study involving Japanese women
By activating matrix Gla–protein (MGP), vitamin K also helps maintain healthy calcium metabolism in vascular tissues, supporting healthy vascular elasticity
Recent studies indicate that vitamin D also potentiates the activity of MGP and that the combination of vitamin K and D provides synergistic support for blood vessel function and bone health
Vitamin K supplementation is contraindicated for those taking Coumadin/warfarin anticoagulant medication.
A unique blend of vitamins K1, K2 and D for healthy calcium utilization to maintain healthy bones and blood vessels.
