Nattokinase is an enzyme derived from a Japanese food known as nattō, which is made from fermented soybeans. Nattokinase helps to maintain healthy fibrinolytic activity and clotting function and promotes healthy circulation and blood flow.1

Life Extension® has determined that optimal fibrinogen levels should range between 295-369 milligrams per deciliter (mg/dL) of blood. Studies indicate that excess fibrinogen is a strong predictor of mortality.2-3 It has been suggested that plasma fibrinogen levels are closely and independently associated with the risk of silent cerebrovascular events.4-5
