Unfortanately, anybody that eats a highly vegetarian or vegan
diet, or purposely avoids the fat
from animal foods typically doesn't get enough vitamin K2 because K2 is almost
entirely found in certain animal foods such as the fat portion of pasture - raised
dairy (butter and cream, full - fat yogurt, kefir, and also full - fat aged cheeses), egg yolks, or in some fermented foods like natto, which most people have never even tried.
