Vitamin K2's chemical name is Menaquinone.  It was until recently believed
to be synthesized by healthy intestinal bacteria and absorbed through the
distal small bowel.  Antibiotics particularly destroy or alter K2.  There is
debate at the moment to taking supplements even if the diet is rich in
natural sources.  Vitamin K2 is used by the tissues to deposit calcium in
appropriate locations, like the bones and teeth.  It also prevents it from
depositing in soft tissues, like arteries.
 
Natural sources of Vitamin K2 through whole foods are #1 Natto, a Japanese
soy product.  Other sources in general order of highest content are
Fermented foods like sauerkraut, kim chee, pickles.  Collard greens,
spinach, salad greens (yes iceberg lettuce too), kale, broccoli, brussel
sprouts, cabbage, olive oil, asparagus, okra, green beans, lentils, hard
cheeses, egg yolk, butter, chicken livers and other organ meats, salami,
ground beef.  Just like Grandma said, eat your vegetables.
 
There's lots of info on this on the internet if you wish to seek further.
Google is a wonderful thing.  Oh, and there is a Vitamin K3 also.
