I'm looking for a natural source of vitamin K2 other than natto and am wondering about the level in fermented bean curd and fermented black beans (both of which, like natto, are fermented soybeans). These two inexpensive items are available at any Asian supermarket. I'd prefer to adhere to the Paleo principle of get nutrients in natural or near-natural form rather than via supplement, when possible.
"Fermented bean curd", for those unfamiliar, usually come in spicy square blocks, packed tightly in glass jar containers, and are traditionally used to flavor food. See the following links:
