Human studies have evaluated nattokinase at ~10,800 FU/day. PBE delivers 13,500 FU per acid-resistant capsule - formulated for high-potency enzymatic activity.
FAQ
-
Nattokinase is a proteolytic enzyme derived from fermented soybeans (natto). It has been studied for its ability to support healthy fibrin breakdown and promote normal blood flow. Research suggests it may help maintain vascular health by supporting the body’s natural balance between clot formation and breakdown.

FU stands for Fibrinolytic Units, a standardized measure of nattokinase activity. It reflects the enzyme’s ability to break down fibrin (a protein involved in clot formation). Higher FU = greater enzymatic activity, not just more weight.
For example, 13,500 FU indicates a high-potency, clinically relevant activity level. -
Nattokinase is a protein enzyme that can be degraded by stomach acid.
Acid-resistant (enteric) capsules help protect the enzyme so it reaches the small intestine intact, where absorption and systemic activity are more effective. -
Nattokinase is typically taken on an empty stomach, either:
30–60 minutes before meals, or
2+ hours after eating
This helps maximize systemic absorption rather than digestion of the enzyme as a protein.

Individuals taking anticoagulant or antiplatelet medications, or those with bleeding disorders, should consult a healthcare professional before use. Avoid use prior to surgery unless directed by a physician.
