  • Title: Effects of magnesium, sodium, calcium or potassium intakes on magnesium content in rat skeletal muscle.
    Author: Gros P, Escanero JF, Alda JO.
    Journal: Rev Esp Fisiol; 1995 Mar; 51(1):1-5. PubMed ID: 7569274.
    Abstract:
    Magnesium skeletal (myocardium and gastrocnemius) content has been studied in rats supplemented with 30 mM dissolutions of Mg2+, Na+, Ca2+ and K+ in drinking water, for 7 or 30 days. In both muscles, the ingestion of Mg2+ for 30 days increased Mg2+ content, while Ca2+ and K+ supplementation caused a significant drop. The increase in Na+ ingestion reduced Mg2+ content in gastrocnemius. There were no significant differences between control and animals supplemented for 7 days. These results suggest that, in the case of supplementation situations, the control mechanisms of the Mg2+ tissular content have a lower gain than those of Na+ and K+ of one order of magnitude.
