Study Identifies Level of Vitamin D Deficiency That Puts People at Risk of Cardiovascular Problems

While vitamin D is best known for its positive effects on bone health, recent research suggests deficiency in this essential vitamin may also be linked to coronary artery disease, heart attacks, and strokes. A new study has found the level of vitamin D deficiency that puts people at risk of developing heart problems.


Participants in the study included more than 230,000 people in the Intermountain Healthcare clinical database. The researchers split the participants into four groups: those with blood levels of vitamin D that were under 15 ng/ml, between 15 and 29 ng/ml, between 30 and 44 ng/ml and greater than or equal to 45 ng/ml.


The researchers followed all of the participants for three years in order to track major adverse cardiac events like death, coronary artery disease, heart attack, stroke, and incidents of heart or kidney failure. They found that the 9% of the patients in the less than 15 ng/ml group had a 35% increased risk of cardiovascular events when compared with the other three groups. Not much difference was found to exist between the risk levels of the other three groups.


The researchers concluded that a deficiency level under 15 ng/ml puts people at higher risk of an adverse cardiovascular event.


Researchers from the Intermountain Medical Center Heart Institute conducted the stud. It was presented at the 2015 American Heart Association Scientific Session in Orlando on Monday, November 9, 2015.


Previous studies have associated vitamin D with reducing the risk of skin damage, reducing the risk of osteoporosis, combating diabetes, and improving age related macular degeneration.


Vitamin D can be found in milk, fortified cereals, fish, and eggs. Your body also processes vitamin D from the sun but it becomes harder for our bodies to process it as we age. A high quality vitamin D supplement is always a good option if you feel that you’re not getting enough through diet and sun.
