Blue Cheese and Vitamin K2

The question of whether blue cheese contains vitamin K2 has been the subject of some debate. Traditional blue cheese, made from unpasteurized milk, is believed to be a good source of vitamin K2. However, pasteurization, a process that kills bacteria, can significantly reduce vitamin K2 content.
