Zero-sugar, stevia-sweetened mix with potassium and magnesium but only 55 mg sodium. Great for flavoring daily water, far too light for heavy sweating or illness.

Our verdicts
Hydration Multiplier
Liquid I.V. is a convenient, good-tasting (to most) way to get a moderate dose of sodium and potassium when you are genuinely sweating, and it earns its popularity on convenience. For daily desk hydration, though, the 11 g of sugar, the $1.50-plus price per stick and the lack of third-party testing make it hard to recommend over water or a cheaper, better-certified mix.

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.
