Nattokinase

How does Nattokinase 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.

Are there safety concerns?

There isn't enough information available to know if nattokinase is safe for most people. Taking two doses of a specific product containing nattokinase (Flite Tabs) seems to be safe. But it is not known if taking more than two doses is safe.

Do not take nattokinase if:

• You are pregnant or breast-feeding.
• You are scheduled for surgery in the next two weeks. Nattokinase might increase the risk of bleeding.
