Nattokinase is an enzyme extracted from natto (fermented soybeans). It is measured in fibrinolytic units (FU), NOT milligrams — a 100 mg is often standardized to about 2,000 FU, which is the amount most commonly used in studies. Early research suggests it may modestly affect blood pressure and clot-related markers, but high-quality human evidence is limited. — per MedlinePlus (U.S. National Library of Medicine).
We link primary sources and paraphrase their findings — never copy their text, tables, or images. Cost-per-dose figures are our own first-party catalog data.

Because nattokinase breaks down fibrin (a blood-clotting protein), it may increase the risk of bleeding — especially alongside anticoagulant or antiplatelet drugs such as warfarin or aspirin — and it should generally be stopped before surgery. People with bleeding disorders or on blood thinners should talk to a healthcare provider first. This is general information, not medical advice. — informed by MedlinePlus (U.S. National Library of Medicine).
Nattokinase may add to the effect of anticoagulant and antiplatelet medications and supplements (warfarin, aspirin, clopidogrel, high-dose fish oil, etc.), increasing the risk of bleeding. — informed by MedlinePlus (U.S. National Library of Medicine).
