Nattokinase shows promise in thrombosis
We explored the potential of nattokinase (NK) in tackling cardiovascular disease, particularly its ability to address thrombosis—an ongoing challenge due to the risks of bleeding from traditional treatments.

Our research demonstrated that NK not only alleviated inflammation and oxidative stress in mouse models but also improved kidney health affected by inflammation.

NK showed remarkable effects by inhibiting key inflammatory responses and reducing harmful proteins related to clot formation. While its promise is evident in early research, further studies are necessary to fully understand its benefits for human cardiovascular health.
We examined how nattokinase affects the progression of atherosclerosis and related biomarkers in a double-blind trial involving 265 participants averaging 65 years old, who had no cardiovascular disease. Participants received either nattokinase or a placebo for three years.

Our findings revealed that nattokinase had no significant effect on subclinical atherosclerosis progression, blood pressure, or other laboratory measures. This indicates that nattokinase may not provide the anticipated cardiovascular benefits in healthy individuals at low risk for heart disease.
We investigated the effectiveness of nattokinase in managing carotid artery atherosclerosis and blood lipids over a 26-week treatment with 82 patients in two groups: one receiving nattokinase and the other statins. Both groups showed reductions in carotid plaque size and artery thickness, with the nattokinase group experiencing notably larger reductions.

While both treatments improved lipid profiles, the statin group saw more significant cholesterol reductions. Notably, nattokinase increased HDL levels, showing promise as a potential alternative to statins in managing atherosclerosis, though its effects appear unrelated to lipid changes.
