Dr. Lawrence Resnick, professor and director of hypertension at Wayne State University, studied the blood pressure of patients who were both diabetic and non-diabetic. He found that all patients with hypertension, whether diabetic or non-diabetic, had lower magnesium levels than people with normal blood pressure. Magnesium is crucial in fighting several common chronic diseases. Resnick says he has treated patients who were hypertensive in spite of taking one or two medications to treat this disease. And that by adding magnesium their pressure returned to normal.
