Life Extension Nattokinase, 90 capsules

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 References 1.
