I realize it's not raw. I'm eliminating all my supplements and attempting to find food that will replace vitamin k-2 (mk7). Natto is a source. I realize it's fermented soy but I'm not sure if there are other animal products in it. thanks.
I have seen natto with some type of fish product (I can't remember what, specifically), but English translation label mentioned this. Also, the brand I saw had a drawing of a fish on the package.
As far as I know, most natto is vegan, but definitely check the label.
