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.

Replenisher Daily Electrolyte Drink Mix

Ultima is an excellent choice if you want a clean, sugar-free, low-sodium way to make plain water more appealing and add some potassium and magnesium. It is not a replacement for a sodium-rich sports or rehydration drink, so heavy sweaters, endurance athletes and anyone recovering from illness should look elsewhere.
