Cardiovascular system support

Nattokinase is a kind of alkaline serine protease with strong fibrinolytic and thrombolytic activity, which is secreted by Bacillus natto and discovered in natto by Sumi et al (1). As an endogenous fibrinolytic enzyme, nattokinase is functionally similar to human plasmin.


  • Provides nutritional support for the maintenance and enhancement of normal healthy endogenous fibrinolysis

  • Provides nutritional support for the inhibition of inflammation and oxidative stress

  • Non-GMO material, non-irradiated, safe for daily use

Nattokinase was reported to lower blood pressure by inhibiting the secretion of angiotensin-converting enzyme I and angiotensin II, and interact with fibrinogen in plasma to reduce blood viscosity, thereby lowering blood pressure (2).

Studies showed that nattokinase attenuates neovascularization in the retinas of mice with oxygen retinopathy (5), thus it can be useful in the treatment of such diseases, as retinopathy of prematurity, diabetic retinopathy, and retinal vein occlusion, additionally, it can be used as a vitreous cleavage supplement in the treatment of proliferative vitreoretinal diseases. 

According to recent studies, Nattokinase has various pharmacological effects, such as improving microcirculation and lowering blood pressure (2), anticoagulation (3), preventing atherosclerosis (4), relieving retinal angiogenesis (5), anticancer (6), inhibiting inflammation and oxidative stress (7). In addition to the research of nattokinase in the fields of thrombosis and hypertension treatment, nattokinase can also be used as a drug or adjuvant to treat diseases such as Alzheimer’s disease (AD)(8), retinopathy (5) , hyperlipidemia (9) and oral mucositis (10).
