RCT: Vitamin D supplementation has no effect on blood pressure in early-stage hypertension

A recent study published in the journal Circulation found that high dose vitamin D supplementation does not significantly reduce blood pressure among patients with pre-hypertension or stage I hypertension.

Approximately one in four U.S. adults have hypertension. Hypertension is a major risk factor for heart disease, which is the number one cause of death in the U.S.

Hypertension is diagnosed based on a blood pressure reading. A systolic blood pressure reading of less than 120 mmHg and a diastolic blood pressure less than 80 mmHg is considered normal.

Slightly elevated blood pressure is known as pre-hypertension. Pre-hypertension is likely to lead to hypertension unless lifestyle changes are made, such as exercising more, losing weight, and eating a low fat, low sodium diet.

One Response to RCT: Vitamin D supplementation has no effect on blood pressure in early-stage hypertension

  1. In my opinion, time duration of this study is only six months. Vitamin acts as a hormone therefore, six month period is quite small to assess its role. They should also check the levels of PTH to correlate it with vitamin D and hypertension.

    Thanks Amber for a nice and informative post again
