Magnesium may lower blood pressure

Taking daily magnesium may modestly lower blood pressure.

Data from 34 clinical trials, involving more than 2000 participants, found a small but significant association between magnesium intake and reduced blood pressure, according to a report in the American Heart Association journal Hypertension.

People receiving a median dose of 368mg of magnesium a day for an average of three months had overall reductions in systolic and diastolic blood pressure.

Taking 300mg per day for just one month was enough to elevate blood magnesium levels and reduce blood pressure.

"With its relative safety and low cost, magnesium supplements could be considered as an option for lowering blood pressure in high-risk persons or hypertension patients," says lead author Yiqing Song. - AAP
