Brief Summary:

Objective : to test the BP lowering-effect of oral magnesium supplementation, as magnesium chloride (MgCl2) solution, 2.5 g daily, in uncomplicated hypertensive type 2 diabetic subjects with decreased serum magnesium levels Design : Randomised double blind placebo controlled trial. Setting : Outpatients with type 2 diabetes from Durango, city in northern Mexico Subjects : 82 subjects between 40 and 75 years of age with type 2 diabetes serum magnesium deficiency and uncomplicated hypertension.

Interventions : During 4 months the intervention group received 2.5 gr of magnesium chloride (50 ml of a solution containing 50 gr of MgCl2 by 1000 ml of solution ). Controls received inert placebo.

Main outcome measure: Change in blood pressure. Increase of serum magnesium Secondary outcomes measures: Changes in lipid profile
