Sources of vitamin K2

Natural vitamin K2 is found in bacterially fermented foods like mature cheeses and curd, but the best source is the traditional Japanese dish “natto,” which is made of fermented soybeans.

Many studies have found that natto consumption in Japan has been linked to significant improvement in K vitamin status and bone health. Unfortunately, the intense smell and “controversial” taste make this soy-food a less attractive source of vitamin K2 for the Western population.

Other sources of vitamin K2 are fermented cheeses, curd and very small amounts in egg yolk and meat.
