OsteoK2® is a unique formulation that, in addition to calcium and vitamin D3, contains MenaQ7TM, a patented extract from Japanese fermented Natto soybeans, which contains the highest amount of natural vitamin K2. Calcium is a mineral necessary for the growth and strengthening of bones, and vitamin D3 enables resorption of calcium from the intestines. The role of vitamin K2 in maintaining bone and blood vessel health has been studied over the last two decades. It is known and proven that vitamin K2 is necessary for the proper utilization of resorbed calcium and its complete incorporation into bones. Vitamin K2 prevents the formation of calcifications in blood vessels, cartilage and soft tissues, which mostly occur in people who continuously take supplements with calcium and vitamin D3. Vitamin K2 is necessary for the activation of the proteins required for calcium binding and its proper utilization – Osteokalcin and MatrixGla proteins. If these proteins are not activated, they cannot bind calcium. Vitamin K2 acts as a cofactor in the activation process of the protein Osteokalcin, which binds calcium and completely incorporates it into the hydroxyapatite-inorganic bone matrix. While the activated MatrixGla protein binds calcium and clears it from blood vessels and soft tissues. OsteoK2® is recommended to all people in middle and old age, especially women, for strong and healthy bones and healthy blood vessels.
