Avoid Counterfeit Nattokinase


Quoted from  Japan Bio Science Laboratory Co., Ltd.

“Despite this significant body of scientific evaluation there are still many companies offering counterfeit enzymes claiming to be Nattokinase. Some examples include peptidase produced by Bacillus subtilis in Japan, protease produced by Genus Bacillus bacteria in China and Taiwan, Chungkinase produced by similar bacteria Bacillus sp. in Korea and protease formulation produced by fungi Aspergillus oryzae in USA that are manufactured and marketed as Nattokinase. Although some of them are close to Nattokinase, they are all different enzymes.

These enzymes do degrade fibrin (artificial thrombus) in a petri dish (in vitro) each to a greater or lesser extent. However, this does not guarantee or describe or even indicate that the same reactions will or might take place in humans (in vivo) when they consume these enzymes. Moreover, since they are different enzymes, the extensive safety data we have undertaken to prove our Nattokinase is safe does not apply to their enzymes. “
