Nattokinase
Biologic
Evidence Summary
A fibrinolytic enzyme from fermented soy, studied in human trials for effects on clotting markers, with one study using an imaging endpoint. There is a dose gap worth knowing about: trials used roughly 10,800 fibrinolytic units, while typical retail products supply 2,000 to 4,000. Evidence generated at the trial dose does not transfer to a product delivering a fraction of it.
