Magnesium supplementation linked to lower blood pressure

Research indicates that magnesium plays a significant role in regulating blood pressure by helping muscles in artery walls relax, which allows blood to flow more easily and reduces resistance for the heart.

Studies, including a major review published in the journal Hypertension, suggest that magnesium supplementation can lead to reductions in both systolic and diastolic blood pressure. Specifically, daily intake of approximately 368 milligrams for three months has been associated with modest decreases in blood pressure readings. Some data suggests that daily doses of 10 to 20 mmol (roughly 360 mg) can achieve an average diastolic reduction of up to 10 mmHg.

Magnesium acts as a natural calcium antagonist and works in exchange with sodium to relax cells, helping to normalize heart rate and protect muscle tissue. Conversely, a deficiency in magnesium is often linked to increased blood pressure, as patients with hypertension frequently exhibit low magnesium levels in their blood and cells.
