Magnesium intake of 500 mg/d to 1000 mg/d may reduce blood pressure (BP) as much as 5.6/2.8 mm Hg. However, clinical studies have a wide range of BP reduction, with some showing no change in BP.
For those who have hypertension, regular physical activity can bring blood pressure down to safer levels. Some examples of aerobic exercise that can help lower blood pressure include walking, jogging, cycling, swimming or dancing. Another possibility is high-intensity interval training.
