Guide : Best Foods with Vitamin K2

Since the discovery of vitamin K in 1929, scientists knew how it can improve bone and heart health. But not until 1970, they could differentiate the roles of vitamin K1 and K2. The Harvard researchers found out that Osteocalcin, a vitamin K2-dependent protein, is needed by our body to take the calcium out of our bloodstream and redirect it to our bones and teeth. It also removes arterial calcification and has beneficial effects on people suffering from cancer, diabetes, Alzheimer’s disease, infertility, etc. It is vital for children’s growth as well.

Though vitamin D also transports calcium from the bloodstream, it cannot decide where to deposit the calcium. The osteocalcin present in vitamin K2 can locate calcium in specific areas of the body, like in soft tissues, bones, and teeth. So, our body needs vitamin K2 to perform this vital job. Despite the significant role vitamin K2 plays in our overall health, most people suffer from vitamin K2 deficiency.

You can get vitamin K2 mostly from animal sources, but it is also present in fermented vegetables. Here are the best foods with vitamin K2 that you can include in your diet.

1. Milk

Cow’s milk or goat’s milk contains vitamin K, but you have to make sure that the animals were pasture raised. Otherwise, they won’t get vitamin K1 that they can convert to vitamin K2, and so we won’t get it either. Even if the cows are fed on hay, you need to make sure that they are not fed on dead hay; else, the milk from the cattle won’t contain vitamin K2. It may not be possible to look into these factors while buying some milk from someone, but if it is, do it.

2. Egg

Eggs from pasture-raised hens provide vitamin K2, but it is not present in eggs from caged hens. You should note that egg yolk from The Netherlands have more vitamin K2 than those from the US, just because of the way the hens are raised. So, you should source eggs from pasture-raised hens and include it in your diet.

3. Natto

The fermented foods, like Natto, provide vitamin K2. But you need to make sure that it is cultured properly and then stored in the refrigerator. You must ensure that it is not pasteurized or contaminated. Even by eating natto once a few weeks, you will be able to fulfill the vitamin K2 requirements of your body. 100 grams of natto contains 1000 mcg of vitamin K2. It also contains other essential minerals such as magnesium, iron, copper, and manganese that make you healthy.

4. Cheese

Various types of cheese such as cheddar, bleu cheese, swiss, gruyere, gouda, jarlsberg, etc. contain vitamin K2. Here are some benefits of including cheese in your diet.

• The Norwegian cheese Jarlsberg is one of the best sources of vitamin K2 and contains 73 mcg of vitamin K2 per 100 grams.
• Gouda cheese is an excellent source of vitamin K2 and this Dutch cheese also contains protein, calcium, vitamin B12, zinc, and phosphorus.

Whether you will get vitamin K2 from cheese sources or not depends on whether the cow is raised on pasture or not, the soil composition and bacteria content in the soil, the fat content, length of fermentation, and other factors.

 5. Meat

Meat is a great source of vitamin K2. Chicken and darker meat provide fat and high amount of vitamin K2. Here are some things you should know about the meat sources of vitamin K2:

Sausage, salami, pepperoni, etc. also contain a high content of vitamin K2. These have high-fat content and can fulfill your needs of vitamin K2. These contain proteins, B vitamins, zinc, and other nutrients as well.

6. Liver

Both goose and chicken liver are good sources of vitamin K2. The organ meats are nutrient-dense and are very good for your health. Research indicates that 100 grams of goose liver contain 369 mcg of vitamin K2. However, it may be difficult to find a goose liver in certain areas. So, you can eat chicken liver instead. Chicken livers are also rich in vitamins A, B2, B12, and folate.

7. Cheonggukjang

This food is lesser known in the Western world and may look like a misspelled word for you. It is a type of fermented bean and curd stew that is native to South Korea and is similar to natto.

You can also include it as topping to your meat-based dishes and desserts.

9. Cream Cheese
