Nattokinase is an enzyme extracted and purified from a food called Natto, which is a food made from fermented soybeans. Natto is produced by fermentation by adding the bacterium Bacillus natto, a beneficial bacteria, to boiled soybeans. The resulting nattokinase enzyme is produced when the bacterium acts on the soybeans. While other soy foods contain enzymes, it is only the natto preparation that contains the specific nattokinase enzyme. Nattokinase (NK for short), also known as subtilisin, is a serine protease produced by Bacillus subtilisl natto during the fermentation of natto. It has the functions of dissolving thrombus, reducing blood viscosity, improving blood circulation, softening and increasing blood vessel elasticity. Nattokinase is a powerful enzyme used to support normal blood flow, circulation, and blood pressure levels. Derived from a highly purified extract of the traditional food Natto, nattokinase is an all-natural, highly active enzyme that helps promote normal levels of fibrin. Fibrin is a filamentous protein formed in blood, which can accumulate along blood vessel walls and affect blood flow.
