The Link Between Arterial Stiffness and Hypertension


The Link Between Arterial Stiffness and Hypertension

 Arterial stiffness is a common condition that affects many individuals, particularly as they age. It is known to be associated with various health issues, including hypertension. In this article, we will explore the causes of arterial stiffness and its connection to hypertension. We will also discuss the role of vitamin K2 in maintaining healthy arteries and provide practical tips for preventing arterial stiffness.

Understanding Arterial Stiffness

Arterial stiffness refers to the loss of elasticity in the walls of the arteries, which can cause them to become rigid and less flexible. This stiffness makes it more difficult for the arteries to expand and contract, hindering the smooth flow of blood throughout the body. Over time, arterial stiffness can lead to serious health problems, including hypertension.

Factors Contributing to Arterial Stiffness

Arterial stiffness can be influenced by various factors, such as age, inflammation, and dietary choices. As individuals get older, their arteries naturally become less elastic, making them more prone to stiffness. Inflammation in the body, often caused by conditions like diabetes or a diet high in carbs and sugar, can also contribute to arterial stiffness. Furthermore, consuming foods rich in omega-6 fatty acids, which are highly inflammatory, can exacerbate the problem.

The Role of Vitamin K2 in Arterial Health

One crucial factor in maintaining healthy arteries is vitamin K2. This essential nutrient plays a vital role in directing calcium to the bones, preventing its accumulation in the arteries. Vitamin K2 activates proteins responsible for keeping the bones strong and reducing the risk of conditions like osteoporosis. Additionally, it helps regulate calcium levels, ensuring that it remains in the bones rather than accumulating in the arterial walls.

Sources of Vitamin K2

Despite its importance, many individuals are deficient in vitamin K2. This deficiency can be attributed to a lack of awareness about its sources. Vitamin K2 is primarily found in foods that are often mistakenly avoided due to their saturated fat and cholesterol content. Sources of vitamin K2 include meats, organ meats, egg yolks, grass-fed butter, dairy products, and yogurt. Fermented foods like natto, popular in Asian cuisine, also provide vitamin K2.

The Link Between Vitamin K2 and Vitamin D3

Vitamin K2 and vitamin D3 work synergistically to promote optimal vascular health. When combined, these vitamins have been shown to improve the vascular profile by reducing arterial wall thickness and minimizing calcium buildup. For every 10,000 IU of vitamin D3, it is recommended to supplement with approximately 100 micrograms of vitamin K2, specifically the MK-7 version for optimal results.

Calcium Supplements and Vitamin K2

It is important to note that taking high doses of calcium supplements without sufficient vitamin K2 intake can actually increase the risk of heart attacks. Studies have shown that individuals, both men and women, who consume at least 1,000 milligrams of calcium per day as a supplement without adequate vitamin K2 supplementation have a significantly higher risk of dying from a heart attack. Therefore, it is crucial to ensure proper vitamin K2 intake when supplementing with calcium.

Warfarin and Its Impact on Arterial Health

Warfarin is a widely prescribed medication used to prevent clotting in individuals with certain health conditions. However, it is essential to be aware of its potential impact on arterial health. Warfarin blocks vitamin K1, which is necessary for normal blood clotting. This action helps prevent clots but also interferes with the specific protein responsible for inhibiting calcification in the vascular system. Consequently, vascular calcification can occur as a side effect of Warfarin treatment.

Tips for Maintaining Healthy Arteries

Maintaining healthy arteries is crucial for overall cardiovascular health. Here are some practical tips to help prevent arterial stiffness and promote optimal arterial health:

  1. Increase Vitamin K2 Intake: Incorporate vitamin K2-rich foods into your diet, such as meats, organ meats, egg yolks, grass-fed butter, dairy products, yogurt, and fermented foods like natto.

  2. Combine Vitamin K2 with Vitamin D3: When supplementing with vitamin D3, consider taking it alongside vitamin K2 to enhance its beneficial effects on arterial health.

  3. Follow a Low-Carb Diet: Adopting a low-carb diet can help reduce inflammation in the body, preventing arterial stiffness and maintaining vascular health.

  4. Limit Omega-6 Fatty Acids: Avoid consuming foods high in omega-6 fatty acids, as they can contribute to inflammation in the arteries.


Arterial stiffness is a common condition that can have serious implications for cardiovascular health, including the development of hypertension. Vitamin K2 plays a crucial role in maintaining healthy arteries by directing calcium to the bones and preventing its accumulation in the arterial walls. By increasing vitamin K2 intake, combining it with vitamin D3, following a low-carb diet, and avoiding inflammatory foods, individuals can take proactive steps to prevent arterial stiffness and promote optimal arterial health. Remember, taking care of your arteries is essential for a healthy heart and overall well-being.
