Social media is full of influencers promoting electrolyte supplements or giving advice on how to make them at home[1]. Experts say that many claims about the health benefits of these drinks should be taken with a grain of salt[1]. Most people get enough electrolytes from their normal diet and drinks[1]. Sodium supplements help to restore fluid balance after prolonged exposure to heat, illness or use of diuretics[1]. Children with prolonged vomiting or diarrhea may be given electrolyte drinks because they lose fluids more easily than adults[1]. People working long hours outside in hot climates or athletes doing intense exercise for more than an hour can benefit from them[1][2]. Excessive use of electrolytes can cause heart rhythm problems, fatigue or nausea[1][3]. The symptoms of an excess of electrolytes resemble the symptoms of their deficiency [1].
