Correction of Furosemide-Induced Magnesium Deficiency with Different Stereoisomers of Organic Magnesium Salts: A Comparative Study

Abstract

We compared the efficiency of different stereoisomers of organic magnesium salts (Mg DL-, Mg D-, and Mg L-aspartate and Mg L- and Mg DL-glutamate) after oral administration under conditions of furosemide-induced magnesium deficiency. The time to complete compensation of erythrocyte magnesium level was 5 days for Mg L-aspartate, 10 and 8 days for Mg L-glutamate and Mg D-aspartate, respectively, and 11 days for Mg DL-aspartate and Mg DL-glutamate. These findings attest to better bioavailability of Mg complex with L-stereoisomer of aspartate in comparison with DL and D-stereoisomers and stereoisomers of Mg glutamate.
