Introduction
LMNT and Liquid I.V. are two widely compared electrolyte drink mixes sold as stick packs. This guide compares publicly available label information — sodium, potassium, magnesium disclosure, sugar, sweeteners, serving format, and dated price per serving — not medical hydration outcomes.
SuppCheckr does not endorse either product for dehydration treatment, hangover-recovery, cramp-prevention, or medical superiority claims. Liquid I.V. Hydration Multiplier is a product/marketing name only — not evidence of superior hydration. LMNT is not better for everyone; high-sodium formulas require individual context and professional guidance when appropriate.
Quick comparison table
Label facts below are for the cited SKUs (Citrus Salt 30-count LMNT; Lemon Lime 16-count Liquid I.V. Hydration Multiplier). Confirm flavor and count before purchase.

| Potassium per serving | 200 mg | 370 mg |
| Magnesium per serving | 60 mg (disclosed) | Not disclosed on cited US Nutrition Facts panel |
| Total sugars | 0 g | 11 g |
| Calories | 0 | 45 |
| Sweeteners | Stevia leaf extract | Cane sugar, dextrose; trace rebiana (stevia) |

Scores reflect label transparency and sourcing — not personal medical suitability.
Sodium difference
LMNT lists 1,000 mg sodium per stick — roughly double the 500 mg sodium listed on Liquid I.V. Hydration Multiplier Lemon Lime sticks in cited Nutrition Facts.
Sodium is an essential mineral involved in normal body processes, including fluid balance, according to NIH Office of Dietary Supplements materials. High supplemental sodium may be inappropriate for some people, including those managing blood pressure, kidney disease, heart disease, fluid restrictions, or certain medications. LMNT's higher sodium per serving is a label fact, not a universal recommendation.
Sugar, carbs, and calories
LMNT lists 0 g total sugars and 0 calories per stick. Liquid I.V. lists 11 g total sugars and 45 calories per stick, with cane sugar and dextrose in the ingredient list.
Sugar and calorie content are label-comparison fields — not medical judgments about which profile is "healthier" for any individual. Shoppers comparing sugar-free versus sugar-containing electrolyte sticks should read Nutrition Facts panels directly.
Sweetener difference
LMNT is sweetened with stevia leaf extract and lists no added sugars on the cited panel. Liquid I.V. uses cane sugar and dextrose as primary carbohydrates, with rebiana (stevia leaf extract) also listed among ingredients.
Sweetener and sugar profiles affect taste and label reading — not medical outcomes. See our sugar-free vs sugar electrolytes guide for category-level context.
Potassium and magnesium on labels
Liquid I.V. lists more potassium per serving (370 mg) than LMNT (200 mg) on cited Nutrition Facts.
Magnesium: LMNT discloses 60 mg magnesium (as magnesium malate) per stick. Magnesium is not listed on the cited US Nutrition Facts panel for Liquid I.V. Hydration Multiplier Lemon Lime — SuppCheckr documents this as not disclosed, not as zero. Do not assume magnesium content from Liquid I.V. marketing copy alone.
Label clarity and claim-risk differences
Both products disclose core sodium and potassium amounts on cited Nutrition Facts. Differences that affect SuppCheckr scoring and shopper scrutiny include:
- LMNT: strong dose transparency for sodium, potassium, and magnesium; high-sodium context; keto/fasting brand positioning (mirrored as brand claims only)
- Liquid I.V.: clear sodium, potassium, and sugar disclosure; magnesium absent from US panel; Hydration Multiplier and faster-hydration marketing — higher claim-risk; SuppCheckr does not endorse hydration outcome claims
Neither product had a verified NSF Certified for Sport or similar program listing matched in the cited review. Thorne Catalyte is the only shortlist product with verified NSF documentation — see the electrolyte supplements comparison for the full five-product table.
Serving format and price per serving
Both are single-serve stick packs mixed into water. LMNT sticks are smaller by weight (~6 g vs 16 g) but list higher sodium per serving.
At the 2026-07-15 manual price check, LMNT Citrus Salt 30-count was $1.50/serving and Liquid I.V. Lemon Lime 16-count was $1.56/serving — similar per-serving cost despite very different sodium and sugar profiles. Retail prices change; verify current price at the retailer before purchase.
Who should be cautious with high-sodium products
According to NIH materials, high sodium intake may be a concern for some people. LMNT's 1,000 mg sodium per stick is materially higher than many daily-hydration formulas (for example, Ultima Replenisher lists 55 mg sodium per stick in the cited product review).
SuppCheckr does not recommend high-sodium or lower-sodium products for any medical condition. People managing blood pressure, kidney disease, heart disease, fluid restrictions, or prescription medications should consult a qualified healthcare professional before using high-sodium electrolyte drink mixes.
When to talk to a healthcare professional
Consult a qualified healthcare professional before starting or changing electrolyte supplements or drink mixes, especially if pregnant, nursing, under 18, taking medication, managing blood pressure, kidney disease, heart disease, fluid restrictions, or a medical condition.
Electrolyte drink mixes are not oral rehydration therapy, IV fluids, or treatment for dehydration, electrolyte imbalance, illness-related fluid loss, heat illness, or hangover recovery.
How SuppCheckr scores them
SuppCheckr product reviews and the comparison table score both products using the electrolytes scoring profile: sodium/potassium/magnesium dose transparency, sugar and sweetener disclosure, label clarity, third-party testing documentation, dated price per serving, formula quality, and claim conservatism.
Published scores for the cited SKUs: LMNT 77, Liquid I.V. 61. Scores are not medical recommendations.
