Based on the results from two prospective studies, (one of which included more than 38,000 men) researchers found that people with low serum Vitamin D have an increased risk of developing high blood pressure. They concluded that Vitamin D may be an independent risk factor for hypertension.
Diet contributes very little to vitamin D levels. Most multivitamins have 200-400IU of vitamin D. An extra 30-60 minutes of sun exposure to the face and arms can generate 4,000IU of vitamin D. This relationship can vary based on latitude and time of year. With fall and winter approaching, our bodies’ ability to make its own Vitamin D is minimal for people in the northern latitudes of the U.S.
Data was collected from the Health Professionals Follow-up Study which began in 1986. The conclusion was that there was a significant increased risk of developing hypertension with vitamin D deficiency.
So, if you have a family history of high blood pressure or other risk factors (diabetes, smoking, overweight, etc.), ask your practitioner to get a serum Vitamin D level. It may reduce your risk for developing hypertension.
