One may have heard about the various benefits Vitamin D, a fat-soluble vitamin, provides for skin, energy and bone health but the awareness regarding Vitamin D being beneficial for heart health is quite low. Recent research has suggested that Vitamin D can improve the overall well- being of the heart and maintain heart health for the better.

Understanding Vitamin D

Vitamin D is a fat-soluble vitamin that is essential for various physiological functions in the human body. Commonly known for its benefits to bone health, especially in women vitamin D aids multiple systems in the body.

Dietary Sources for Vitamin D include fatty fish (that are rich in omega-3), cod liver oil, egg yolks and Cheese. Another popular source of the vitamin is sunlight.

Vitamin D is a vital nutrient for overall health, and ensuring you get enough through sunlight, diet, or Vitamin D supplements is important for maintaining your well-being, especially for bone and immune system health.

The Importance of Vitamin D

A few of the benefits Vitamin D provides include:

1. Calcium and Phosphate absorption –

Vitamin D is known to aid the absorption of calcium and phosphate in the body, especially in the small intestine. Calcium as commonly known is the mineral that keeps bones healthy and strong. Hence a deficiency in Vitamin D would lead to deteriorated bone health.

2. Immune system –

Vitamin D is known to ward off dangerous infections and safeguard the body by strengthening the immune system.

3. Vitamin D for heart health –

The vitamin helps reduce the risk of cardiovascular disease and aids in maintaining the overall health of the heart.

The Connection Between Vitamin D and Heart Health

The research regarding the relationship between Vitamin D and the heart is an ongoing one but many studies have shown that Vitamin D helps in improving heart health through these processes:

  1. Vitamin D may help regulate Blood Pressure in the body as it causes a relaxation of the blood vessels which leads to lower blood pressure. High BP is a significant risk factor for heart disease.
  2. Vitamin D has anti-inflammatory properties, and chronic inflammation is believed to play a role in the development of atherosclerosis (hardening of the arteries) and other cardiovascular conditions.
  3. The vitamin is said to regulate the cardiovascular rhythm and deficiencies in Vitamin D have been linked to an increased risk of arrhythmias (irregular heartbeats).
  4. Low Vitamin D levels have been associated with an increased risk of several cardiovascular risk factors, including obesity, insulin resistance, and diabetes.

Sources of Vitamin D

Sunlight enables the production of Vitamin D, one of the most important vitamins required to maintain overall body health. Our bones depend on Vitamin D to effectively absorb the calcium we obtain from our food, which in turn helps to keep our bones and teeth strong. Without an adequate supply of Vitamin D, our bodies cannot properly take in calcium.

Vitamin D is also found in food such as fatty fish like salmon and trout, cod liver oil, egg yolks, mushrooms and cheese. The effectiveness of the vitamin depends on how these natural sources of Vitamin D have been cooked. Additionally, it can be challenging to get enough Vitamin D from diet alone, so sunlight exposure is an important source for most people.

Vitamin D is commonly taken through additional supplementation because of its convenience and efficiency. Supplementation provides accurate dosages and can be effective in treating Vitamin D deficiencies.

Benefits of Vitamin D for the Heart Health

1. Regulation of the blood pressure:

The Renin-Angiotensin System is a process that requires Vitamin D through which the renin-angiotensin-aldosterone system (RAAS) regulates blood pressure. It can help suppress the production of renin, a hormone that constricts blood vessels and raises blood pressure.

2. Anti-Inflammatory Properties:

Vitamin D has anti-inflammatory effects on the body. Chronic inflammation is one of the leading factors in the development of heart illnesses like atherosclerosis (hardening and narrowing of the arteries).

3. Lowering LDL Cholesterol:

It is said that Vitamin D may help lower low-density lipoprotein (LDL) cholesterol, which is also commonly called the “bad” cholesterol. High levels of LDL cholesterol are associated with an increased risk of heart disease like congestive heart failure.

4. Increased HDL Cholesterol:

On the other hand there is high-density cholesterol (HDL) which is considered to be the “good” cholesterol. HDL is said to transport cholesterol away from the arteries.

How to Get Adequate Vitamin D

While the sun is often considered the best natural source of Vitamin D, it’s important to note that effective but safe sun exposure is necessary. This is because sunlight contains not only beneficial Vitamin D but also harmful UV rays that can cause damage to our skin.

While basking in the sun for Vitamin D it is important to keep these guidelines in mind –

  • To keep sun exposure in moderation as over-exposing can cause physical damage to one’s skin.
  • Spend time in the sun during the early morning or late afternoon because, during these times of the day, the intensity of the UV rays is much lower.
  • If one is expected to be in the sun for a long time it is advised to apply SPF 30+ sunscreen or wear protective clothing to minimize UV damage.
  • Individuals living in higher altitudes may require more sun exposure than individuals in other low-lying areas.

Other natural sources of Vitamin D include fatty fish like salmon, cheese, cod liver oil, mushrooms and fortified juices like orange juice.

One of the best ways to get adequate Vitamin D is through Vitamin D supplements which is essentially Vitamin D tablets. The appropriate dosage of Vitamin D supplements can vary based on individual needs. It is advised to consult a healthcare professional before starting any form of supplementation.

Risks of Vitamin D Deficiency

A Vitamin D deficiency can show up through symptoms like:

  • Fatigue
  • Bone and chest pain
  • Changes in mood/ mental health decline
  • Hair loss
  • Pale skin

A deficiency could also increase the risk of diseases such as osteoporosis (weakening of the bones), osteomalacia (softening of the bones), reduced immune function, hypertension, and depression.

Monitoring and maintaining one’s Vitamin D levels keeps a check on any deficiencies. This can be done through blood tests, including it in your diet and through Vitamin D supplements.


When one’s existing diet paired with additional Vitamin D consumption from natural sources is not enough it might be a good idea to turn to supplementation as it is a convenient form of filling the Vitamin D gap in one’s everyday nutrition. Some of the cases where an individual could benefit from supplementation include:

  • People with darker skin have more melanin in their body which inhibits the absorption of Vitamin D into the skin via the sun. Individuals with darker skin tones may benefit from supplementation as they do not reap the full benefit of sun-sourced Vitamin D.
  • Individuals living in colder and darker climates (such as in the northern hemisphere) have less exposure to the sun hence limiting their chances of receiving Vitamin D from the sun.
  • Inflammatory bowel diseases like chrons reduce the absorption of nutrients within the digestive tract and hence Vitamin D helps in increasing the level of absorption to aid overall body well-being.
  • Pregnant and breastfeeding women may require additional Vitamin D to support the growth and development of their baby’s bones.
  • Vegetarians/vegans/dietary-restricted individuals may need to consume Vitamin D through supplementation as the natural sources may not fit into their chosen diet.

The Role of Healthcare Professionals

Before starting any new health routine or adding to an existing routine it is vital to consult a healthcare professional who will be able to give personalized advice and accurate details of what is needed for each individual. As healthcare professionals are experts in their fields, talking to one before beginning supplementation may lay out the individual’s guidelines.They take into account factors like individual medical history, family history, lifestyle, and specific risk factors. Similarly through diagnostic tests like blood tests, one can determine if they would require Vitamin D supplementation or can obtain it adequately through their current diet.

Lifestyle Factors and Heart Health

1. Unhealthy Diet:

Eating better can lower your risk of heart disease and stroke. This means the inclusion of healthy foods like vegetables and fruits and the reduction of fast food and processed food. Certain types of heart vitamins may also help in keeping the heart healthy.

2. Lack of Exercise:

Being active benefits your heart, brain, muscles, bones, and mood. Exercise is scientifically proven to improve the overall body and improve heart health as well considering how it helps with cardiovascular functioning.

3. Unhealthy Weight:

Being overweight/obese causes a significant amount of health problems such as hypertension, bone issues, muscle issues and damaged heart health.

4. Smoking:

Smoking is one of the deadliest forms of external harm to the body as it affects not only the heart but many other systems. A healthy heart is one that is not exposed to smoke.

5. Excessive alcohol:

Just like smoking excessive amounts of alcohol not only damages the heart but affects major organs like the liver.

Hence it is important to note that having Vitamin D in one’s diet or using supplementation is not enough to benefit heart health. For improved heart health one must also maintain a balanced diet and get adequate exercise.


Vitamin D has an important role in the maintenance and well-being of the heart. It is proven to promote better heart health because of its beneficial features such as reducing hypertension, reducing cholesterol and improving muscle and bone health. A holistic approach to heart health, including a balanced diet, exercise, and regular check-ups, is essential for overall well-being. It is also vital to consult with a healthcare specialist when starting additional supplementation.


Can you take Vitamin D with heart medication?

Taking Vitamin D with heart medications is considered safe but it depends on the type of medication being taken.

Is Vitamin D good for heart palpitations?

Vitamin D may help with heart palpitations depending on the dosage of the vitamin.

How long does it take to see improvements in heart health with Vitamin D supplementation?

The results are varied but it is estimated that it takes around 12 months to see improvements in heart health with Vitamin D supplementation.
