Nattokinase dissolves 94% blood clot at ten minutes and degrades the fibrin clot after two hours of incubation[2].

Nattokinase (150-250 mg/kg; oral gavage twice daily for 2 days) exhibits fibrinolytic activity and dissolves blood clots in vivo[3]. Animal Model: Sprague-Dawley (SD) rats (180-220 g) are injected κ-Carrageenan[3]Dosage: 150, 250 mg/kg Administration: Oral gavage twice daily for 2 days Result: Increased the plasma concentration of fibrin/fibrinogen degradation products (FDPs) and D-Dimer in a dose-dependent manner. Decreased the fraction of the vessel cross section occupied by thrombosis.
