title: Cardio-protective contribution of hard waters to magnesium in-take.
abstract: The reported inverse correlation between water hardness and incidence of cardiac fatalities has led to tentative hypotheses concerning the role of magnesium intake in this phenomenon. The present article reviews the evidence in favor of the magnesium hypothesis, with emphasis on differentiating between diet-derived and water-borne magnesium intake, and their respective cardio-protective potentials.
