6. Ground Beef
One of the greatest sources of protein, medium fat ground beef is also a decent source of vitamin K2. It contains 8 mcg per 3.5 ounce serving. Eat about 500 grams (17 ounce) of minced beef and you would also be consuming nearly all the vitamin K2 you need in a day.
7. Chicken Liver
Only a few people eat chicken liver nowadays. If you happen to be one of them, it is a good thing as chicken liver is quite rich in vitamin K2. The amount of vitamin K2 for every 3.5 ounce of chicken liver is around 12 mcg. It is also a good source of vitamin A, which a lot of people are deficient in.
