Magnesium reduces blood pressure
Up until now, evidence linking magnesium to better blood pressure has been inconclusive.

Researchers in one review looked at all the magnesium studies to date and found 22 trials involving 1,173 people who took 120 mg to 973 mg of magnesium per day for 3 to 24 weeks. Combining the data, doctors found that overall, magnesium reduced systolic blood pressure by 3 to 4 mmHg, and diastolic blood pressure by 2 to 3 mmHg, with the best results for doses over 370 mg of magnesium per day. The blood pressure measurements, systolic and diastolic, relate respectively to when the heart contracts to pump blood out, and when it relaxes to refill.

In discussing their findings, doctors said supplementing with magnesium appears to achieve a “small but clinically significant reduction in blood pressure,” and they suggest larger controlled trials to confirm these results.
