Zero Sugar Electrolyte Powder: How the Top Brands Compare
Liquid IV, LMNT, Cure, and 2THIRTY — broken down by sugar, sodium, calories, ingredients, and price per serving. The complete shopper's guide.
Why Zero Sugar Matters in an Electrolyte Powder
Sugar in a hydration drink is mostly there for two reasons: taste and shelf appeal. Neither helps you hydrate.
In fact, added sugar actively works against the goal:
If you're taking electrolytes for performance, recovery, or to feel better — zero sugar isn't a preference. It's the right tool for the job.
The Top Zero-Sugar Electrolyte Powders Compared
LMNT
Ultima Replenisher
Cure Hydration (Zero-sugar line)
2THIRTY
Side-by-Side Cost Per Serving
| Brand | Sticker Price | Per Serving | Subscription Price |
|---|---|---|---|
| LMNT | $45 / 30 ct | $1.50 | $1.35 |
| Ultima | $20 / 30 ct | $0.67 | $0.55 |
| Cure | $24 / 16 ct | $1.50 | $1.27 |
| 2THIRTY | $45 / 30-serving tub | $1.50 | $1.33 (Club) |
Plain electrolyte powders come in cheaper per serving. 2THIRTY sits at the functional end of the shelf — adaptogens, B-vitamins and liver support in the same scoop — so the fair comparison is a stack of two or three products, not a single salt mix.
The Bottom Line
If you only care about sodium replacement after sweat sessions — LMNT.
If you want the cheapest possible zero-calorie option — Ultima.
If you want clean-label simplicity — Cure.
If you want a zero-sugar electrolyte powder that also supports your energy, your liver, and your morning after — that's the niche 2THIRTY owns.
Pick the one built for the job you're actually trying to do.
