Vitamin D and risk of future hypertension

Posted on: March 15, 2013   by  Vitamin D Council

A meta-analysis published in the European Journal of Epidemiology reports that if you’re sufficient in vitamin D, you may have a decreased risk of high blood pressure. Uncontrolled high blood pressure can lead to heart attack, stroke, metabolic syndrome, and even heart failure.

Researchers included eight publications discussing eleven studies for their analysis. Seven of the studies reported vitamin D status as serum blood levels, and four reported vitamin D intake from the diet. Participants were followed for a range of 1 to 14 years.

Out of 283,500 subjects, 33,800 people reported hypertension, or high blood pressure, during follow-up. The authors found that having vitamin D levels among the top one-third of participants decreased the risk of hypertension by 30%. For every 10 ng/ml increase in vitamin D status there was a 12% decreased risk of hypertension.

The authors didn’t find any significant effect in studies that assessed vitamin D status using intake from dietary sources.

The authors call for further research to “determine whether vitamin D therapy may be beneficial in the prevention or the treatment of hypertension.”
