Can Vitamin D Deficiency Cause Heart Palpitations?

Vitamin D deficiency is becoming a widespread health concern in the United States. A 2009 study published in the “Archives of Internal Medicine” estimated as many as 77 percent of Americans are vitamin D deficient. Vitamin D is essential for bone health, but it also helps regulate the levels of minerals in your body -- including minerals important for heart function. As a result, vitamin D deficiency can cause changes in mineral levels, which in turn can negatively affect your heart. If you're suffering from heart palpitations, seek immediate medical attention.

Vitamin D: The Basics

Vitamin D is a fat-soluble nutrient that is essential for bone health. It is responsible for the regulation of certain minerals such as calcium and magnesium. Vitamin D can be obtained by eating oily fish such as salmon or milk that is vitamin D fortified; however, maintaining healthy levels of vitamin D through diet alone is not likely. Vitamin D is also made by your body when you skin is exposed to the ultraviolet B rays from the sun. Recent pushes for sunscreen use and the prevention of skin cancer has led to the increase in vitamin D deficiency as sunscreen blocks these rays.

Vitamin D deficiency can contribute to heart palpitations because if its importance in calcium regulation. Calcium is a mineral that is essential to bone and heart health. It can be found in foods such as dairy products, fish, spinach, kale and broccoli. Calcium is dependent on vitamin D for absorption, and low vitamin D levels also affect the levels of calcium in your body. Hypocalcemia, or low calcium levels, can cause symptoms such as numbness and tingling in the extremities, muscle cramps, poor appetite and abnormal heart rhythms and palpitations.


Vitamin D's interaction with magnesium also affects your heart. Magnesium is an essential mineral in the body and, according to the National Institutes of Health, is responsible for over 300 different chemical reactions in your body. Vitamin D plays a role in the regulation of magnesium in your body, and low levels of vitamin D can affect the levels of magnesium. A magnesium deficiency can cause symptoms such as anxiety, sleep disorders, muscle spasms, seizures and abnormal heart rhythms and palpitations. Increased vitamin D supplementation, according to the National Institutes of Health, is sometimes used to treat people with a magnesium deficiency.
