Degradative Effect of Nattokinase on Spike Protein of SARS-CoV-2

“In this study, we examined the effect of nattokinase on the S protein of SARS-CoV-2. When cell lysates transfected with S protein were incubated with nattokinase, the S protein was degraded in a dose- and time-dependent manner. Immunofluorescence analysis showed that S protein on the cell surface was degraded when nattokinase was added to the culture medium. Thus, our findings suggest that nattokinase exhibits potential for the inhibition of SARS-CoV-2 infection via S protein degradation.”

Nattokinase decreases plasma levels of fibrinogen, factor VII, and factor VIII in human subjects

“In summary, this study showed that oral administration of nattokinase could be considered as a CVD nutraceutical by decreasing plasma levels of fibrinogen, factor VII, and factor VIII.”

Serrapeptase and nattokinase intervention for relieving Alzheimer's disease pathophysiology in rat model

“The present results support our hypothesis that the oral administration of proteolytitc enzymes, SP and/or [nattokinase], would have an effective role in modulating certain factors characterizing AD. Thus, these enzymes may have a therapeutic application in the treatment of AD.”
