Get the Japanese Superfood List
Recently, I have been getting many comments on my YouTube Channel.
Thank you very much for leaving comments.
One of them was this.
Natto King says nattokinase is destroyed by heat over 50 degrees
centigrade, but I’ve also heard that freezing natto can destroy the k2
in the natto, which is another important health benefit of natto.
Can anyone confirm that?
So I made a video to answer the question.
