Natto-Serrazime is a unique blend of two very potent fungal proteolytic enzymes Nattozimes? and Serrazimes? derived from Aspergillus oryzae and Aspergillus melleus which are used for cardiovascular, anti-inflammatory, respiratory, as well as immune support. Nattozimes? and Serrazimes? in studies, have shown to have the same thrombolytic and fibrinolytic activities as the popular enzyme products Nattokinase and Serrapeptidase therefore, they can be used as a 1:1 substitution for these applications.
