What the studies say
This randomised crossover study assessed the effects of magnesium supplementation on blood pressure in patients with hypertension. For 8 weeks, participants received 20 mmol/day of magnesium in the form of magnesium oxide. The results indicated that supplementation led to small but significant reductions in blood pressure measured in the doctor’s surgery, at home and over a 24-hour period.
