A study published in the JAMA Internal Medicine has found that vitamin D supplements have not been found effective in reducing blood pressure. Therefore, the research team recommends that it should not be used as an antihypertensive agent.

The study findings have challenged the earlier suggestions that the vitamin D could be used as treatment for high blood pressure. The researchers have conducted a review of trials and patients.

Study's lead researcher Dr. Miles Witham, of the School of Medicine at Dundee, Scotland, affirmed that large-scale studies have shown that people with low vitamin D levels have more chances to have higher blood pressure.

"It hasn't been clear though whether giving vitamin D to people actually lowers their blood pressure as individual trials have been too small to find out the answer", affirmed Witham. Researchers from the UK, the US, Australia, New Zealand, India and Europe have worked in unions to assess trial and patient data.

The data was of 46 trials in which vitamin D was used to lower blood pressure. Individual patient data was from 27 trials. The researchers affirmed that they extracted data to know vitamin D levels, systolic and diastolic blood pressure, changes in blood pressure over time and participant demographics.

Dr. Witham affirmed that by gathering all these things and putting them into one analysis, they have been able to show that vitamin D supplements do not lower blood pressure.

The researchers think that the study findings are important as many doctors recommend and have already recommended that patients with hypertension should take vitamin D. Dr. Witham said that their work has already proved this would not work. Therefore, the vitamin cannot be recommended as a way to help control high blood pressure.

To lower blood pressure, one should eat healthy foods, consume less salt, limit alcohol intake, reduce stress and quit smoking.
