Vitamin D Deficiency Linked to Heart Disease


Chapter 12


Vitamin D Deficiency


Heart Disease

When it comes to heart disease, everyone thinks of cholesterol. What most people don’t know is that vitamin D deficiency is also linked to heart disease. Is there any scientific evidence to show the relationship between vitamin D deficiency and heart disease?


Evidence For The Link Between

Vitamin D Deficiency And Heart Disease

Scientific evidence to show the link between vitamin D deficiency and heart disease continues to grow. In an article (1) published in 1989 in Lancet, a respected British Medical Journal, a researcher noted a relationship between latitude and heart disease: the farther you live from the equator, the lower you are in vitamin D and the higher your risk for heart disease. 

Over the years, numerous studies continue to show a relationship between low vitamin D level and heart disease.  However, this vital information hardly received any public attention until 2008 when two studies finally got the attention of the news media.

In the first study (2), published in January 2008 in Circulation (the official journal of the American Heart Association), researchers of Framingham Heart Study in Framingham, USA, followed 1739 participants for the development of heart disease. The mean follow-up was 5.4 years. These researchers found a nearly 2-fold increase in the risk for heart disease in individuals who had a low level of vitamin D. 

In the second study (3), published in the June 9, 2008 issue of the Archives of Internal Medicine (the official journal of the American Medical Association), investigators from Harvard School of Public Health in Boston, USA, looked at the level of vitamin D in 18,225 men in the Health Professionals Follow-up Study: These men were free of any heart disease at baseline. During a 10 year follow-up period, 454 men developed a heart attack. The results were stunning: the lower the vitamin D level, the higher the risk for heart attack. Men whose 25 (OH) vitamin D level was at least 30 ng/mL (75 nmol/L) had roughly half the risk of a heart attack compared to men who had a 25 (OH) vitamin D level below 30 ng/mL (75 nmol/L).........................
