The research, done at Aristotle University in Greece, found that supplementation with 600 milligrams of magnesium pidolate per day (which supplies about 60 milligrams of magnesium as an amino acid chelate), produced a small decrease in 24-hour blood pressure among people with mildly elevated blood pressure.
People in the study taking the magnesium supplement had an increase in the levels of magnesium and potassium inside their blood cells and a decrease in the levels of calcium and sodium.
