In a report published in the European Journal of Clinical Nutrition, the researchers also discovered that the measure of the effect increased in proportion with increased dosage.
Cardiovascular diseases cause almost 50% of deaths in Europe and contribute heavily to escalating healthcare costs. Elevated blood pressure or hypertension is a major risk factor for mortality from cardiovascular and renal disease.
Causes of hypertension include smoking, an inactive, sedentary lifestyle, a diet high in sodium and an inadequate intake of specific nutrients, especially minerals such as potassium, calcium and magnesium.
“Until now, there’s been inconclusive evidence regarding the effect of magnesium supplements on blood pressure,” explained the researchers from the University of Hertfordshire. “So we conducted a meta-analysis by analysing data from twenty-two trials involving 1,173 people to assess the effect of magnesium on blood pressure.”
In the trials, the magnesium supplementation doses ranged from 120 to 973 mg with between 3 to 24 weeks of follow-up. Although not all individual trials showed significance in blood pressure reduction, by combining the trials, the overall data indicated that daily magnesium supplementation reduced both systolic and diastolic blood pressure. The best results were observed at the higher dosages.
“The clinical significance in the reductions found from this meta-analysis may be important in helping to prevent hypertension and associated risks around cardiovascular disease,”the researchers reported … “And is worthy of future trials using solid methodology.”
