The September 2017 issue of the American Journal of Clinical Nutrition reported the results of a meta-analysis (looking at many different studies and results, and crunching the numbers), which concluded supplementing with magnesium reduces blood pressure in men and women with insulin resistance, prediabetes, or non-communicable chronic diseases including diabetes and cardiovascular disease.
“To our knowledge, the effect of magnesium supplementation on blood pressure in individuals with preclinical or non-communicable diseases has not been previously investigated in a meta-analysis,” writes Daniel T. Dibaba of Indiana University.
For their analysis, the researchers selected 11 randomized, controlled trials that included a total of 543 participants. Magnesium doses ranged from 365 milligrams (mg) per day to 450 mg per day consumed for 1 to 6 months. Control groups received a placebo or no treatment. Blood pressure was measured at the beginning and end of the trials.
In a pooled analysis of all trial participants, supplementing with magnesium was associated with a greater reduction in systolic and diastolic blood pressure compared to the controls. When blood-pressure measurements obtained at the beginning of the trials were compared to those at the trials’ conclusions, supplementing with magnesium was associated with an average reduction of 4.18 mmHg systolic blood pressure and a 2.27 mmHg decrease in diastolic blood pressure.
The authors observed that magnesium may directly lower blood pressure as well as improve preclinical conditions and chronic diseases that predispose people to develop hypertension. “Magnesium supplementation may play a role in breaking the cycle between the preclinical conditions and type-2 diabetes and cardiovascular diseases through the lowering of blood pressure,” they write.
“The pooled results suggest that magnesium supplementation significantly lowers blood pressure in individuals with insulin resistance, prediabetes, or other non-communicable chronic diseases.” Dr. Dibaba and colleagues conclude.
Are you supplementing with magnesium? If not, it’s something you may want to consider.
