NutriMK7 ® is a dietary supplement, formulated with natural vitamin K2, in the form of menaquinona 7, and vitamin D. Vitamin K2 is extracted from Natto (fermented soybeans). The menaquinona 7 is the long chain molecule of vitamin K2, which offers increased efficiency and low-dose bioavailability. This natural form of vitamin K2 helps set the calcium bone structure, while helping to reduce the calcification of the arteries. These two effects that seem contradictory in principle, are possible because this vitamin activates a specific protein (osteocalcin), responsible for optimizing the binding of calcium in the bone structure. This function is vital to the strength of bones, which helps to prevent the onset of osteoporosis. Thanks to vitamin K2, also activated protein (matrix GLA) in the blood vessels, which prevents the calcium deposit on their walls. As a result, helps prevent calcification and hardening of the arteries, and exerts a protective effect against cardiovascular disease. In NutriMk7 vitamin D was added to reinforce the action of menaquinona-7, especially in the care of bone health.
