LMNT scored 70/100, the top of our electrolyte coverage — a clean, fully disclosed product whose only real question is whether 1,000 mg of sodium suits you. Unusually for a supplement category, every major rival discloses its amounts, so choosing an alternative is really choosing a sodium dose.

The alternatives, by sodium dose

01Step down slightly — Earth Energy Daily Hydration (750 mg): the everyday middle path, zero sugar, 2.5:1 potassium ratio, every amount printed, at $0.71–$1.33 a serving. Our pick if LMNT’s gram is more than you need, below.
02Step down more — Nuun Sport (300 mg, 54/100): the light, portable tablet for everyday hydration rather than hard sweat — cheapest sticker, priciest per milligram.
03Lowest sodium — Just Ingredients (100 mg, 54/100): a real-food, potassium-forward option for people who already get plenty of salt — the opposite end of the ladder from LMNT.

The checklist to judge any electrolyte

This category makes it easy: check the sodium per serving against your needs, the sugar (0 g to 11 g across the field), and the cost per 100 mg of sodium rather than the sticker. The full five-product comparison runs every number.
