A study recently published in the Journal of Hypertension suggests that lower intake of magnesium may boost risk of hypertension or commonly known as high blood pressure. Researchers from the University of Hertfordshire analyzed data from previous studies and found that taking a magnesium supplement in a dose ranging from 120 to 973 mg for three to 24 weeks reduced both systolic and diastolic blood pressure.

In a recent study entitled: "Effect of magnesium supplementation on blood pressure..." There was greater blood pressure reduction in crossover trials, which means when people with high blood pressure were not on magnesium, their blood pressure was higher; when they were on magnesium their blood pressure was lower. Also, the higher the magnesium dosage, the lower the blood pressure.

Doctors at the Harvard School of Public Health have completed a study to determine the relationship between diet and hypertension (high blood pressure). The study involved over 30,000 male health professionals 40 to 75 years old.

A double-blind controlled trial was recently carried out by Dutch and Belgian researchers in order to determine if oral supplementation with magnesium is an effective way of lowering blood pressure in women suffering from mild to moderate hypertension.

The researchers conclude that replacing common table salt with a low sodium, high potassium, high magnesium mineral salt is an effective way of lowering blood pressure in older people suffering from mild to moderate hypertension.
