Nattokinase for Blood Circulation

Research suggests that nattokinase may support blood circulation by breaking down fibrin and fibrinogen, the proteins central to blood clot formation, and that this fibrinolytic activity could potentially be enhanced when combined with certain unsaturated fatty acids such as linoleic acid, EPA, and DHA. The available evidence on this specific mechanism comes from a single 2020 laboratory study that identified compounds in foods like red pepper as modulators of nattokinase activity, finding that unsaturated fats amplified clot-dissolving effects while saturated fats appeared to inhibit them. Studies indicate the enhancement works by altering the structural conformation of fibrin and fibrinogen rather than acting on the enzyme itself. It is worth noting that the current evidence base for this particular interaction is limited to preclinical research, and broader conclusions about nattokinase's effects on blood circulation in humans would require clinical trials to substantiate these early findings.
