This study, conducted by the universities of Rio de Janeiro and Glasgow, aimed to evaluate the effects of oral magnesium supplementation on blood pressure and vascular function in women with high blood pressure. The participants were divided into a group receiving a magnesium supplement (600 mg/day) and a group receiving a placebo. In addition, all women received conventional drugs. Several parameters, blood pressure, and vascular functions were measured at the start of the study and after 6 months. The study showed better control of blood pressure, improved function of cells in heart and blood vessels, and amelioration of early-stage atherosclerosis in the patients supplemented with magnesium. This means that magnesium supplementation should be considered as adjuvant therapy in people with high blood pressure. Further details can be found in the study.
