Vitamin K2 is essential for maintaining proper functions of the body. It has a significant impact on the maintenance of healthy bones. Vitamin K2 plays an important role in calcium economy because together with vitamin D3 it cares for strong bones, and assimilates the easiest in the form of MK7. This vitamin modifies and activates proteins in such a way as to give them the ability to bind calcium and place it in where needed. Vitamin K2 is also important for the functioning of osteocalcin – a protein synthesized in the cells responsible for bone formation, the so-called osteoblasts. It also prevents calcification of atherosclerotic plaques and development of cardiovascular diseases.Furthermore, vitamin K2 participates in the blood coagulation process, as it regulates the production of prothrombin that affects blood coagulation.
