2. Fibrinolytic activity in plasma is improved;

3. The content of t-PA in plasma has increased. Because of its safety, stability and good thrombolytic effect, NK can be used as an oral reagent for thrombosis treatment.

4. Because nattokinase can reduce platelet aggregation and blood viscosity by dissolving thrombus, nattokinase is widely used in health care products for cardiovascular and cerebrovascular diseases, mainly because nattokinase has obvious effects and less side effects, and can be applied to various diseases of different patients.

5. The blood vessels of patients with cardiovascular and cerebrovascular diseases will be hardened to varying degrees, resulting in slow blood flow in the human body. In order to deliver nutrients to various tissues and organs of the human body on time, the heart has to increase the intensity of pumping blood, which also invisibly increases blood pressure and increases the burden on the heart. Nattokinase can soften blood vessels, prevent blood vessels from being blocked by thrombus, and reduce the risk of sudden death of patients with cardiovascular and cerebrovascular diseases. Moreover, the hypotensive effect of nattokinase is very lasting and remarkable, and it can maintain the stability of blood pressure for a long time, and it will not produce side effects if eaten frequently.

6. Nattokinase also has strong oxidation resistance, which can destroy the chemical bond of free radicals, thus destroying the function of free radicals, and plays an important role in preventing Alzheimer's disease, resisting fatigue and delaying aging.
