Main uses: In the medical field: Magnesium aspartate is a commonly used electrolyte supplement medication that can be used to treat arrhythmias, especially those caused by electrolyte imbalance. It regulates the electrophysiological properties of cardiac muscle cells and stabilizes the cell membrane potential, thereby improving heart rhythm. Additionally, it has an adjunctive therapeutic effect on chronic and acute hepatitis, cirrhosis, and other liver diseases, helping to improve liver function and promote the repair and regeneration of liver cells. This is because magnesium ions activate various enzymes within liver cells, participating in the metabolic processes of the liver. In other fields: Magnesium aspartate may also be found in some sports nutrition supplements. Athletes who take it can replenish the magnesium ions lost through intense exercise, which helps to alleviate muscle fatigue and enhance athletic performance.
