LMNT is one of the top electrolyte supplements, but not necessarily better than all competitors. LMNT's main advantages are its great taste, mixability, and inclusion of magnesium and calcium along with sodium and potassium. The pre-packed servings are convenient. However, some people may prefer other brands based on factors like price, caffeine content, or magnesium forms. There is no definitive "best" electrolyte overall.
