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.
