Nattokinase is a fibrinolytic enzyme that breaks down fibrin. Fibrin is the protein by-products of blood coagulation/clotting. Nattokinase has been shown to reduce vessel wall thickening following endothelial injury. Proper regulation of fibrinolysis can help maintain healthy blood flow throughout the body by ensuring that organs and tissue receive the blood and oxygen required. The nattokinase in this formula has high enzyme activity providing 20,000 fibrin (FU) per gram and is free of Vitamin K. We also implement Nattokinase as a part of our Ten Pass Ozone Therapy program.
