Nattokinase is great for cardiovascular wellness and support of healthy circulation. It is a unique enzyme produced during the fermentation process used to create the traditional Japanese food Natto (a gooey soybean dish). The Nattokinase enzyme is recognized as "fibrinolytic" and its activity is measured in "fibrinolytic units" (FU). Research suggests that fibrinolytic enzymes like Nattokinase promote healthy blood flow to support circulatory and cardiovascular health.
