Vitamin D deficiency occurs when there is not enough vitamin D in the body. This deficiency weakens bones, but its relationship to blood pressure is not completely clear. However, research has revealed a potential link between vitamin D deficiency and high blood pressure.
Research shows that vitamin D can influence the body’s blood pressure regulation by influencing certain chemicals that keep the lining of blood vessels healthy and flexible. When vitamin D levels are low, arteries become stiffer, making it harder for blood to flow through them.

A study published in the journal Cureus found that for every 10 percent increase in 25-hydroxyvitamin D levels, the risk of high blood pressure decreased by 8.1 percent. Although this correlation is not necessarily alarming, it does suggest a potential link between vitamin D deficiency and high blood pressure.
Importance of vitamin D screening
Screening for vitamin D deficiency is especially important for people with brown or black skin, as they have higher levels of melanin and have a harder time making vitamin D from sunlight. People with low sun exposure, older adults, and people with certain health conditions that affect vitamin D absorption may also benefit from screening.
What you can do
If you’re concerned about your vitamin D levels and their potential impact on your blood pressure, take a simple blood test to check your vitamin D levels.
Increasing your vitamin D intake may require spending more time in the sun and consuming vitamin D-rich foods such as eggs, milk, and cheese. However, it’s important to note that while vitamin D is essential for overall health, more isn’t necessarily better. According to the National Academies of Sciences, Engineering, and Medicine, adults should aim for 600 to 800 international units (IU) of vitamin D per day, with an upper limit of 4,000 IU per day.
