Vitamin K2 Goes Beyond Bone Health

author avatar Dr. Eric Berg 04/17/2024

While most people understand how important vitamins are to the body, not many fully understand how vitamin K2 helps vital organs function.

Learn about how vitamin K2 works, how it helps different parts of the body, and the best way to get enough of this nutrient.

The Multifaceted Functions of Vitamin K2

Primarily known for its role in bone formation, vitamin K2 aids immune cell production and acts as an endocrine gland.

Osteocalcin, vital for bone health, is produced when vitamin K2 enters the body. This means that vitamin K2 ensures stronger bones and prevents joint problems.

The Impact of Vitamin K2 on Insulin Resistance and Sensitivity

Have you ever thought about how your body manages sugar? That's where insulin comes in. It helps our cells use glucose for energy, but sometimes, things can go awry.

Balancing Insulin Levels with Vitamin K2

Cellular insensitivity to insulin prompts the pancreas to produce more of it, resulting in fat accumulation. Research has shown that vitamin K2 could be a game changer here.

Vitamin K2 is crucial in regulating insulin levels and reducing fat storage. One study revealed that those who ingested vitamin K supplements experienced a heightened insulin sensitivity after four weeks.

This means they need less insulin to help their cells absorb glucose.

Anti-Inflammatory Properties of Vitamin K2

Vitamin K2, much like its close relative vitamin D, is a potent anti-inflammatory agent. It helps to reduce inflammation in the body by inhibiting pro-inflammatory markers.

The power of vitamin K2 goes beyond just bone health; it's also essential in managing chronic diseases linked to inflammation.

Chronic low-grade inflammation is known as the silent killer because it contributes to conditions like heart disease and diabetes without noticeable symptoms until the late stages.

But why? One reason could be due to its role in blood clotting - when our bodies experience damage or infection, they respond by creating clots that cause swelling and redness (inflammation).

Adequate amounts of vitamin K help control these reactions, preventing unnecessary harm from excessive inflammation.

The Influence of Vitamin K2 on Energy Capacity and Testosterone Levels

Vitamin K2's influence extends beyond bone and blood health. One surprising benefit is its role in enhancing energy capacity, especially during physical exertion.

Boosting Energy Capacity with Vitamin K2

Vitamin K2 plays a crucial part in mitochondrial function, the powerhouses of our cells. It aids in optimizing energy production, which is essential for sustained physical activity.

Moreover, it enhances mitochondrial resilience against stressors that often accompany strenuous exercise. This lets you go further without feeling worn out so quickly.

Balancing Testosterone Levels with Vitamin K2

But there's more. vitamin K2 not only boosts energy but also helps maintain balanced testosterone levels in both men and women for optimal health.

Research shows that this versatile nutrient may assist both men and women by promoting healthy testosterone levels, contributing to overall well-being and vitality.

Foods Rich in Vitamin K2 and Its Production

Certain foods contain vitamin K2, a vital nutrient for overall health. One of the richest sources is nattō, a Japanese dish of fermented soybeans.

Cheese lovers will be happy to know that hard cheeses are also high in vitamin K2 due to the fermentation process.

Identifying Vitamin K2-Rich Foods

The levels of this nutrient can vary significantly between different types of cheese - gouda and brie come out on top as they're prosperous.

You can also get your dose from egg yolks and butter from grass-fed cows. A study suggests incorporating these foods into your diet could help reap more benefits than just bone health.

The Production of Vitamin K2

Our bodies don't typically produce this essential nutrient but obtain it through diet or supplements. Interestingly, bacteria during fermentation processes produce most dietary forms of vitamin K2. Research shows that fermented dairy products like kefir have an edge over non-fermented counterparts in terms of their vitamin content.

Fracture and Vitamin K2

The interplay between vitamin D and vitamin K2 is crucial for fracture healing.

Vitamin D is essential for calcium absorption, a mineral vital for bone health. However, vitamin K2 is equally important because it helps direct the calcium you absorb to your bones, preventing it from accumulating in soft tissues like arteries and joints.

This partnership ensures calcium is deposited correctly, aiding in bone mineralization and fracture repair.

But what's the correct vitamin D dose for fracture healing? The optimal dosage can vary depending on individual needs and the severity of the fracture. Consulting with a healthcare professional is essential to determine the appropriate vitamin D intake for your situation.

Ensuring adequate vitamin D and K2 levels can significantly contribute to the healing process and overall bone health, reducing the risk of complications during fracture healing.


Vitamin K2 plays a crucial role in various bodily functions, including bone health, insulin regulation, inflammation reduction, and energy optimization.

Obtaining sufficient vitamin K2 through diet or supplementation is essential for overall health and well-being. Incorporating vitamin K2-rich foods like nattō, hard cheeses, egg yolks, and grass-fed butter can help ensure an adequate intake of this vital nutrient.

Understanding the interplay between vitamin K2 and other nutrients like vitamin D is also crucial for promoting bone health and overall vitality. By prioritizing the intake of vitamin K2 and seeking guidance from healthcare professionals, individuals can support their health and prevent chronic conditions.
