Label Comparison

LMNT vs Liquid I.V.: zero-sugar sodium vs ORS-style sugar

Both are mainstream electrolyte powders, but the labels live in different lanes: LMNT is a high-sodium, zero-sugar formula; Liquid I.V. is an ORS-inspired sugar-and-salt formula. Same shelf, different chemistry.

Formula summary

LMNT is the high-sodium, zero-sugar profile; Liquid I.V. is the moderate-sodium, carbohydrate-containing ORS-inspired profile.

The honest read

These two products get cross-shopped constantly, but the labels encode different design choices. LMNT is a 1000mg-sodium / 0-sugar electrolyte mix where the priority is sodium without carbohydrate. Liquid I.V. is a 500mg-sodium / 11g-sugar drink built around ORS-style sodium-glucose cotransport logic; the sugar is part of the formula architecture, not only flavoring.

On absolute price, both sit in the same neighborhood: LMNT at roughly $1.50 a stick and Liquid I.V. at roughly $1.56 a stick at full retail. Per-serving cost is not a meaningful differentiator. The cost-per-mineral story does diverge because LMNT delivers about 6x the sodium for the same dollar, while Liquid I.V. spends more of the formula budget on sugar and potassium.

On magnesium, LMNT includes 60mg of magnesium malate per stick; Liquid I.V. includes none. That is a label difference, not a medical promise. A label-matched DIY version can preserve either profile and can also model a magnesium addition separately if you want to explore that variant.

For reverse engineering, the clean read is category-based: LMNT models a high-sodium zero-sugar powder, while Liquid I.V. models a moderate-sodium sugar-plus-electrolyte packet. Either label-matched DIY version is buildable in Lyte Lab from bulk ingredients at a much lower ingredient cost.

Formula profiles

LMNT label profile

LMNT Electrolyte Drink Mix

  • ·1000mg sodium per stick, the highest sodium dose in this pairing.
  • ·0g sugar and no carbohydrate-driven cotransport component.
  • ·Includes 60mg magnesium malate; Liquid I.V. lists no magnesium.
  • ·Single-serve powder stick with a premium direct-to-consumer brand position.

Liquid I.V. label profile

Liquid IV Hydration Multiplier

  • ·500mg sodium per stick, about half of LMNT's sodium.
  • ·11g sugar per stick, aligned with an ORS-inspired sodium-glucose formula.
  • ·380mg potassium per stick, nearly double LMNT's potassium.
  • ·Single-serve powder stick with broad retail distribution.

Or skip both — label-matched DIY versions are ~5-10¢/serving

Both formulas are reproducible from bulk minerals at a fraction of retail. Lyte Lab has tool-generated DIY recipes for each, with shopping lists and per-ingredient SKU links.

Frequently asked

Which label is closer to an ORS-style formula?+
Liquid I.V. is closer because it combines 500mg sodium with 11g sugar and 380mg potassium. That makes it the sugar-plus-electrolyte profile in this pairing. LMNT intentionally removes sugar and pushes sodium higher.
Which label is lower carb?+
LMNT. It lists 0g sugar, while Liquid I.V. lists 11g sugar per stick. Lyte Lab treats that as a formula-category difference, not a diet recommendation.
Why does Liquid I.V. have so much potassium relative to LMNT?+
Liquid I.V. lists 380mg potassium per stick versus LMNT's 200mg. That is roughly double on the label. This comparison treats it as a formulation choice and does not infer that either potassium amount is appropriate for a particular person.
Is the sugar in Liquid I.V. really necessary?+
Sugar is part of the ORS-style design. SGLT1 (sodium-glucose cotransporter 1) moves sodium most efficiently when glucose is present in roughly a matching molar range. Removing sugar would create a different label profile rather than a lower-sugar version of the same formula.
Can I model both formulas in Lyte Lab?+
Yes. The builder can model LMNT's high-sodium zero-sugar profile and Liquid I.V.'s moderate-sodium sugar-plus-potassium profile as separate presets. That is useful for cost comparison and ingredient exploration, not medical guidance.
What if I want LMNT's sodium dose but with the cotransport sugar?+
That is a custom formula, not a label match. In Lyte Lab terms it would be a high-sodium, sugar-containing variant: 1000mg sodium plus 11g sugar. That should be treated as a modeling exercise unless a clinician or qualified sports-dietitian has told you otherwise.
