Our verdicts
Hydrating Electrolyte Mix
Cure is one of the cleanest and most transparent everyday electrolyte mixes available, with published batch testing and no added sugar or artificial sweeteners. Its moderate sodium makes it best for daily hydration and ordinary workouts rather than heavy sweating or illness, and you pay a premium for the ingredient list.

Sport Electrolyte Tablets
Nuun Sport is a well-certified, low-sugar and reasonably priced way to add electrolytes to everyday drinking and moderate workouts, which makes it our pick for general and athletic use under an hour or two. Heavy sweaters and anyone battling illness-related dehydration should look to a higher-sodium mix or a medical ORS instead.
