Provita Nattokinase - 100 mg - Nattokinase is a potent blood-clot dissolving protein produced by the bacterium Bacillus subtilis during the fermentation of soybeans to produce Natto. Extensively used in Japan, Korea and China to treat cardiovascular disease, it has been recently recognized by Western medicine for its potent fibrinolytic (anti-clotting/antithrombotic) capacity. In medical terms, Nattokinase was shown to be capable of blocking thromboxane formation resulting in an inhibition of platelet aggregation and formation of clots without producing the side effect of bleeding (unlike the common Aspirin). Nattokinase can dissolve formed thrombi and also prevent their formation, thus maintaining cardiovascular health.
