We compared the anticoagulant and fibrinolytic effects of the major functional food products generated by Bacillus subtilis natto. We analyzed NSK-SDR and NKCPR powders that consist mainly of nattokinase and bacillopeptidase F, respectively. The specific activity of the plasmin-like activity of NKCPR H was about 2.5-fold higher than that of NSK-SDR. Although both NSK-SDR and NKCPR reduced fibrin monomer levels in human blood, the anticoagulant effect of NKCPR was over 100-fold higher than that of NSK-SDR. Dietary supplements with anticoagulant and fibrinolytic effects might play an important role in preventing thrombotic diseases.
