Complementary vascular-protective actions of magnesium and taurine: A rationale for magnesium taurate

Abstract 

By a variety of mechanisms, magnesium functions both intracellularly and extracellularly to minimize the cytoplasmic free calcium level, [Ca²⁺]_i. This may be the chief reason why correction of magnesium deficiency, or induction of hypermagnesemia by parenteral infusion, exerts anti hypertensive, anti-atherosclerotic, anti-arrhythmic and antithrombotic effects. Although the amino acid taurine can increase systolic calcium transients in cardiac cells (and thus has positive inotropic activity), it has other actions which tend to reduce [Ca²⁺]_i. Indeed, in animal or clinical studies, taurine lowers elevated blood pressure, retards cholesterol-induced atherogenesis, prevents arrhythmias and stabilizes platelets — effects parallel to those of magnesium. The complex magnesium taurate may thus have considerable potential as a vascular-protective nutritional supplement, and might also be administered parenterally, as an alternative to magnesium sulfate, in the treatment of acute myocardial infarction as well as of pre-eclampsia. The effects of magnesium taurate in diabetes deserve particular attention, since both magnesium and taurine may improve insulin sensitivity, and also may lessen risk for the micro- and macrovascular complications of diabetes.
