                                Research has confirmed that nattokinase retains a remarkable amount of its enzymatic power, with one study showing over 95% activity remaining even after five freeze-thaw cycles. This finding offers a clear answer: freezing does not destroy nattokinase, but merely pauses its function until it is thawed.
