During the past 10 years, at least sixteen clinical trials have been performed using Menatetrenone, and every single one has found that K2 supplements protect bone health. Menatetrenone has been shown to slow, halt and actually reverse not the loss of bone mass. Vitamin K2 can dramatically reduce the risk of suffering a bone fracture.
Menatetrenone has health benefits that extend well beyond the skeletal system. Emerging science is now documenting the role of vitamin K - and specifically of Menatetrenone - in protecting our cardiovascular health, and the health of that all-important organ, the brain
Vitamin K2 menatetrenone (MK-4), a form of vitamin K2 made in the body from phylloquinone (vitamin K1) and distinct from the menaquinones made by probiotic bacteria. Available science indicates that vitamin K2 - and especially menatetrenone - is superior to Vitamin K1 in maintaining the health of the bones and vascular system. Clinical trials have proven that high-dose vitamin K2 does not cause excessive or abnormal blood clotting, although it will interfere with "blood thinning" medications.
Vitamin K is an essential nutrient, best known for its role in blood clotting. Plants make one form of vitamin K (phylloquinone, or vitamin K1) for their use. But your body doesn't use all of the K1 in your diet "as is." Instead, the body converts some of this plant form of the vitamin into a different vitamin K molecule: Menatetrenone, or MK-4, a form of vitamin K2. Tissues vary in their vitamin K needs, and it's become clear that some tissues have a specific need for Menatetrenone, which is not met by phylloquinone. For some purposes (like blood clotting), phylloquinone works fine; but extensive evidence shows that Menatetrenone has unique effects on bone health not shared by phylloquinone.
