Arterial Stiffness and Vitamin D

author avatar Dr. Eric Berg 04/10/2024

Decreased cardiovascular health and arterial stiffness become bigger concerns as you age. Keeping your heart healthy should be a top priority for everyone no matter how old you are.

Learn about what causes arterial stiffness and what steps you can take to prevent it.

The Impact of Vitamin D on Arterial Stiffness

Ever thought about the connection between sunlight and your arteries? It's not as far-fetched as it might seem. When exposed to sunlight, our skin produces vitamin D, a nutrient essential for maintaining health.

But here's where things get interesting: studies show that having enough vitamin D in your system could help keep your arteries flexible.

The Role of Vitamin D as an Anti-Inflammatory

Vitamin D plays several roles in our bodies, but one crucial function is its power to fight inflammation. Chronic inflammation can lead to stiffer arteries over time.

A fascinating randomized clinical trial found that taking 4,000 IUs of vitamin D3 daily for four months significantly reduced arterial stiffness among young African Americans who were overweight or obese and deficient in this vital nutrient.

This vitamin seems to act like a natural anti-inflammatory agent within the body.

Getting more sun exposure or supplementing with quality sources of vitamin D may be promising strategies for improving arterial elasticity.

The Synergistic Effect of Vitamin D3 and K2 on Arterial Health

Regarding heart health, vitamins D3 and K2 make a powerful duo. These two work in tandem to keep your arteries flexible and free from calcium deposits, which are a common cause of arterial stiffness.

Understanding the Recommended Ratio of Vitamin D3 to K2

Vitamin K2's role is crucial; it keeps calcium out of the arteries and guides it toward where it’s needed most: our bones.

But how much should you take? Research indicates that to experience maximum benefits for arterial health, 100mcg of vitamin K2 is necessary per 10,000IU (International Units) of vitamin D3. This ratio offers optimal benefits for arterial health.

This combination helps reduce arterial stiffness and promotes healthy bone density—an added bonus. Remember, as with any supplement regimen, always consult a healthcare provider before starting.

Fasting and Its Effects on Arterial Elasticity

Fasting has been demonstrated to enhance arterial flexibility, making it a natural way of maintaining excellent blood vessel health.

Fasting as a Complementary Approach to Vitamin D Supplementation

Consider adding regular fasts if you're already taking vitamin D supplements for their health benefits. Why? Because combining these two strategies might supercharge your fight against hypertension.

The science is straightforward: Fasting helps reduce inflammation throughout the body, including within our arteries. This reduction in inflammation leads to improved arterial elasticity.

This improvement could be even more pronounced when paired with adequate vitamin D supplementation. The anti-inflammatory properties of fasting and vitamin D create a powerful duo that works together to support healthy blood pressure levels.

The Ketogenic Diet and Arterial Elasticity

An exploration of how a ketogenic diet, known for reducing insulin levels and inflammation, can support arterial elasticity.

Insulin Resistance and Vitamin D Absorption

Understanding how insulin resistance can hinder the absorption of vitamin D3, leading to deficiency.

But how does a keto diet play into this? Well, insulin resistance often goes hand-in-hand with arterial stiffness. When your body becomes resistant to insulin - an issue that a ketogenic diet can alleviate - it may hinder the absorption of vitamin D3.

This leads to deficiency, which isn't ideal because vitamin D is vital for our overall health and beneficial for maintaining artery flexibility. And when arteries are flexible, they're healthier.

Research has demonstrated that people who stick to a keto diet usually have lower insulin concentrations and decreased inflammation, both of which help enhance arterial suppleness.

Factors Contributing to Vitamin D Deficiency

Our bodies need a healthy dose of vitamin D, but various factors can lead to its deficiency. The most common one is the lack of sun exposure. Many people spend their days indoors, missing out on the natural sunlight that triggers vitamin D synthesis in our skin.

The Role of Sun Exposure in Vitamin D Synthesis

Sunlight is a vital factor in the body's capacity to create vitamin D. However, due to modern indoor lifestyles and concerns about skin cancer from excessive sun exposure, many individuals don't get enough sunshine for optimal health.

Liver or gallbladder problems are also significant contributors since these organs are crucial for processing fat-soluble vitamins like D.

Another contributing factor is obesity; excess body fat can sequester more of the nutrient and alter its release into the circulation.

Inadequate dietary intake may be another cause. Fatty fish like salmon are excellent sources, but if you're not a fan or have allergies, it might be hard to get sufficient amounts through diet alone.


Maintaining cardiovascular health and preventing arterial stiffness should be prioritized at all ages. Understanding factors like vitamin D deficiency and inflammation is crucial.

Vitamin D acts as a natural anti-inflammatory, supporting arterial flexibility. Supplementing with vitamin D, especially with vitamin K2, can reduce stiffness.

Lifestyle choices like fasting and a ketogenic diet may also improve arterial elasticity by reducing inflammation and insulin resistance.

Addressing vitamin D deficiency through increased sun exposure and dietary changes is vital for heart health.

By incorporating these strategies, individuals can promote arterial health and reduce cardiovascular risk. Always consult a healthcare professional before making significant lifestyle changes.
