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