Uses: In the medical field: As an electrolyte supplement, it can be used to prevent and treat hypokalemia (low potassium levels in the blood) caused by various reasons, and to correct the deficiency of potassium ions in the body. For example, in cases of low potassium levels resulting from the long-term use of potassium-excreting diuretics, potassium aspartate can effectively replenish potassium ions and maintain the body's electrolyte balance. At the same time, it has a certain regulatory effect on the electrical physiological activities of the heart, helping to stabilize the heart rhythm. In other fields: It can be found in some sports drinks or nutritional supplements, where it helps athletes replenish the potassium ions lost through excessive sweating, maintaining the normal contraction and relaxation of muscles, and reducing the occurrence of muscle fatigue and cramps.
