How does it work?
Nattokinase decreases the ability of blood to clot. This "thins the blood" and might protect against conditions caused by blood clots such as stroke, heart attack, and others.
High blood pressure. Research suggests that taking nattokinase (NSK II, Japan Bio Sciences Laboratories Company Ltd., Japan) daily for 8 weeks can reduce blood pressure in people with high blood pressure.
Deep vein thrombosis (DVT). There is some evidence that taking a specific combination product (Flite Tabs) might decrease the chance of getting a blood clot in the legs during long plane flights. This product combines a blend of 150 mg of nattokinase plus pycnogenol. Two capsules are taken 2 hours before the flight and then again 6 hours later.
“Hardening of the ateries” (atherosclerosis).
Peripheral artery disease (PAD).
