Top Foods Rich in Vitamin K2
Essential Sources for Bone Health
Vitamin K2, a lesser-known but equally important member of the vitamin K family, plays a crucial role in calcium metabolism and cardiovascular health. Found predominantly in animal-based and fermented foods, this vitamin supports bone health and helps prevent arterial calcification.
Understanding which foods are rich in vitamin K2 can empower individuals to make informed dietary choices that support overall health. By including a variety of vitamin K2-rich foods in the diet, one can ensure they are meeting their nutritional needs effectively.
1) Natto
Natto is a traditional Japanese dish made from fermented soybeans. It is well-known for its high vitamin K2 content. A typical 100-gram serving provides around 17% of the daily value of vitamin K2.
The fermentation process used to make natto creates a unique texture and flavor. This process is also responsible for its health benefits.
Natto is particularly valuable for vegetarians and vegans. Unlike many animal-based sources, natto offers a plant-based option for obtaining vitamin K2.
In addition to vitamin K2, natto contains several other nutrients. These include protein, fiber, and various vitamins and minerals, making it a nutritious food choice.
Eating natto regularly can support bone and heart health. Vitamin K2 in natto helps increase bone density and reduce the risk of arterial calcification.
2) Brie Cheese
Brie cheese is a notable source of vitamin K2. It contains MK-7, a form of vitamin K2 that is beneficial for bone health and cardiovascular function.
A 1-ounce (28 grams) serving of Brie provides essential vitamins and minerals. It includes calcium, phosphorus, and B-12, making it nutrient-dense.
Brie’s rich, creamy texture makes it appealing. It pairs well with fruits, nuts, and whole-grain crackers. It can be enjoyed in various dishes or simply on its own.
Adding Brie to a balanced diet can help increase vitamin K2 intake, supporting the body's essential functions. Remember to consume it in moderation due to its calorie and fat content.

Natto is particularly rich in vitamin K2, specifically in the form of menaquinone-7 (MK-7), which is known for its benefits to bone and cardiovascular health.
Miso is another fermented soybean product. This Japanese fermented soybean paste is known for its unique, earthy flavor and is commonly used in miso soup. While it's less potent in vitamin K2 compared to natto, it still offers a notable amount.
Tempeh, a fermented soybean cake originating from Indonesia, also provides vitamin K2. It's made by fermenting cooked soybeans with a specific type of mold, resulting in a firm and earthy product. Consuming fermented soybeans like tempeh can contribute to your daily intake of vitamin K2.
These foods not only offer vitamin K2 but also come with the added benefits of probiotics due to fermentation. Probiotics can support gut health and enhance nutrient absorption. Including a variety of fermented soybean products in the diet can be a convenient and tasty way to meet the body's vitamin K2 needs.
8) Eel
Eel stands out as a unique source of vitamin K2, offering a seafood alternative to the more commonly recognized animal-based sources.
A 100-gram serving of eel provides approximately 63 micrograms of vitamin K2. This quantity meets the recommended daily intake, making eel a nutritious choice for those looking to increase their vitamin K2 consumption.
In addition to vitamin K2, eel is rich in vitamins A and B12, essential for eye health and overall well-being. It also supplies a significant amount of dietary protein, contributing to muscle health and maintenance.
Eel was once more popular in Western diets because of its affordability and nutritional benefits. Reintroducing eel into modern diets can provide a valuable boost of essential nutrients.
9) Grass-Fed Beef
Grass-fed beef is a potent source of vitamin K2, particularly the MK-4 form. This nutrient is essential for bone health and cardiovascular function. The diet of grass-fed cattle contributes to a higher concentration of vitamin K2 compared to grain-fed animals.
The nutritional profile of grass-fed beef is enriched by the natural diet of grazing on pasture. It helps elevate levels of several vitamins, including vitamin K2, which plays a role in the modulation of calcium in the body.
In addition to vitamin K2, grass-fed beef offers beneficial omega-3 fatty acids and antioxidants like vitamin E. These compounds can further support overall health. Regular consumption of grass-fed beef can contribute significantly to dietary vitamin K2 intake.
Choosing cuts like the liver, steaks, or ground beef from grass-fed cattle ensures a higher intake of vitamin K2. This makes grass-fed beef an excellent addition to a diverse and nutrient-rich diet.
Grass-fed beef’s enhanced nutrient profile highlights the importance of diet quality in livestock and its direct impact on human nutrition. The shift towards grass-fed options can help individuals meet their vitamin K2 needs effectively.
10) Egg Yolk
Egg yolks stand out as one of the rich sources of Vitamin K2. Depending on the hen’s diet, an egg yolk can contain between 46 to 192 micrograms of this essential nutrient.
The diet of the hen plays a significant role in determining the K2 content of the egg yolk. Hens that are pasture-raised and consume a diet rich in grass and insects typically produce eggs with higher levels of Vitamin K2 compared to those fed industrial grains.
Incorporating egg yolks into your diet is a practical way to boost your Vitamin K2 intake. They can be prepared in various ways, making them a versatile addition to your meals.
The Role of Vitamin K2 in the Body
Vitamin K2 is crucial for various bodily functions, particularly in maintaining bone density and supporting cardiovascular health. _ It works by aiding calcium regulation and placement throughout the body_.
Bone Health Benefits
Vitamin K2 plays a significant role in bone health. It activates osteocalcin, a protein that helps bind calcium to the bone matrix. This process is vital for bone mineralization and strength.
Studies have shown that adequate Vitamin K2 intake is linked to higher bone density and lower fracture rates. It is particularly crucial for postmenopausal women, who are at higher risk for osteoporosis.
Foods rich in Vitamin K2, such as certain cheeses and fermented foods, can support this process. Including these foods in one's diet can make a notable difference in maintaining healthy bones.
Cardiovascular Health
Vitamin K2 is essential for cardiovascular health. It helps regulate the deposition of calcium in the arteries, preventing arterial calcification. This action reduces the risk of arterial stiffness and cardiovascular diseases, including heart attacks.
Menaquinone, a form of Vitamin K2, is effective in preventing excess calcium buildup in arteries. Research has indicated that higher Vitamin K2 intake is associated with better heart health.
Consuming foods like natto, a fermented soy product, and certain animal products can provide the necessary Vitamin K2. Regular intake of these foods can contribute to maintaining a healthy cardiovascular system.
Understanding Different Types of Vitamin K2
Vitamin K2, also known as menaquinone, exists in several forms. The most commonly recognized forms are MK-4 and MK-7, which differ in their sources and health benefits. These variations affect how the body absorbs and utilizes the vitamin, making it crucial to know where they come from.
MK-4 and MK-7: What’s the Difference?
MK-4 is primarily found in animal products such as egg yolks and chicken. It has a shorter half-life, meaning it stays in the bloodstream for a shorter period. This form of Vitamin K2 is vital for bone health and arterial flexibility.
MK-7 is prevalent in fermented foods like natto, a traditional Japanese dish made from fermented soybeans. It has a longer half-life, which allows it to remain in the blood longer, providing extended benefits for bone and cardiovascular health. Both MK-4 and MK-7 contribute to the carboxylation of osteocalcin, a process essential for bone mineralization.
Natural Sources of Vitamin K2
Animal Sources: Foods such as chicken, especially darker cuts like wings and thighs, contain high levels of MK-4. Dairy products, particularly cheeses, are also rich in Vitamin K2.
Fermented Foods: Fermented food items, including natto, provide substantial amounts of MK-7. These foods are exceptional for those seeking plant-based sources of Vitamin K2. Unlike MK-4, MK-7 from fermented foods can offer prolonged benefits due to its longer half-life.
Understanding the differences and sources of MK-4 and MK-7 can help you make informed dietary choices to enhance your health effectively.
