Superiority

There are three forms of vitamin K supplements available today, including synthetic vitamin K1 (phylloquinone), synthetic vitamin K2 as MK-4 (menaquinone), and natural vitamin K2 as MK-7 (menaquinone-7).

Current recommended intakes of vitamin K are based on the body’s need for vitamin K to coagulate (clot) blood. Vitamin K-dependent proteins are involved in clotting blood in the liver, and the Western diet provides ample vitamin K1 for this need.

However, for tissues other than the liver, the significant source of vitamin K in the diet is the menaquinones, or vitamin K2. Vitamin K2 from dietary sources, including egg yolk, meat, and especially fermented cheeses, have been linked to bone health and heart health in many international studies. In other words, increasing natural vitamin K2 intake from dietary sources results in healthier bones and a healthier cardiovascular system.

Superiority of MenaQ7

The Western diet is unfortunately vitamin K2 deficient. Experts therefore recommend supplemental vitamin K2 either as dietary supplements or as food enrichment.

A scientifically-based comparison between synthetic MK-4 (menaquinone) and natural vitamin K2 as MK-7 clearly demonstrates significant differences in several areas.
