Magnesium may reduce blood pressure in people with high blood pressure, according to new findings. The study adds to data from epidemiological studies that have reported more magnesium, potassium and calcium may reduce your risk of hypertension.
Researchers recruited 155 people to take part in a double-blinded, placebo-controlled, randomized trial. The subjects were randomly assigned to receive either daily supplements of magnesium oxide or a placebo for 12 weeks.
At the end of the study, no significant differences were at first observed. However, when the researchers looked specifically at hypertensives, significant decreases in both systolic and diastolic blood pressure were observed in the magnesium group.
