The Verdict
LMNT scores meaningfully higher on our rubric (68 vs 57 on our 0-100 execution score), mainly because its 1000mg sodium with zero sugar fits the actual purpose of an electrolyte mix better than Liquid I.V.'s lower sodium and added sugar. On cost, LMNT runs about $1.50 per serving versus Liquid I.V.'s $1.28. In our view, LMNT is the stronger pick for hydration performance - especially for low-carb, endurance, or heavy-sweat use - while Liquid I.V. is a sweeter everyday option if you do not mind the added sugar and lower sodium.

Why This Comparison Matters
LMNT and Liquid I.V. are two of the most-marketed electrolyte brands, but they are built for different jobs. LMNT is a high-sodium (1000mg), zero-sugar mix aimed at low-carb, heavy-sweat, and endurance users; Liquid I.V. is a lower-sodium mix that leans on added sugar and its glucose-based transport system for everyday hydration. This is the high-sodium-no-sugar-versus-sweeter-everyday decision.
Sodium is the electrolyte that matters most for rehydration, and the two products sit far apart on it. Added sugar drives Liquid I.V.'s taste and its osmotic transport claim but is a downside for anyone watching sugar.
We scored both on evidence, quality, cost per serving, and transparency.
Detailed Score Breakdown
Recharge Electrolyte Drink Mix - Citrus Salt
LMNT
1,000mg sodium, 200mg potassium, 60mg magnesium per stick - the highest sodium dose in the category. Appropriate for heavy sweaters, low-carb dieters, and endurance athletes; excessive for sedentary daily use
Clean ingredient list (salt, citric acid, magnesium malate, potassium chloride, natural flavor, stevia) but NOT third-party certified - no NSF, Informed Sport, or BSCG seal despite premium positioning
$1.50/serving at 30 sticks for $45 - premium pricing for a product that is essentially salt, potassium chloride, and magnesium malate
Fully transparent label, exact mineral doses disclosed, no proprietary blends
1,000mg sodium per serving - by far the highest in the category. Zero sugar, stevia-sweetened. Marketing implies daily use, but a single stick delivers 43% of the AHA-recommended daily sodium ceiling. Best for endurance athletes and strict keto, NOT a daily wellness product
Hydration Multiplier - Lemon Lime
Liquid I.V.
500mg sodium, 370mg potassium plus 11g added sugar - intentionally formulated around WHO oral rehydration ratio using sodium-glucose cotransport. The sugar is not a flaw, it is the mechanism
Owned by Unilever; manufactured in cGMP facilities but NOT third-party certified for sport (no NSF or Informed Sport seal)
$1.28/serving at 16 sticks for ~$20 - pricing has crept well past the mid-range tier it used to occupy
Full label disclosure, but markets 'Cellular Transport Technology' which is just the well-known sodium-glucose cotransport mechanism rebranded
11g added sugar per stick is the SGLT1 cotransport mechanism at work - the same principle as WHO ORS. Useful for actual rehydration; unnecessary for healthy adults sipping it daily as a 'wellness' habit
How We Compared These Products
Every product in our database is scored on four equally-weighted pillars: dosing accuracy and form quality, purity verification (third-party testing), cost per clinically effective dose (not cost per pill), and label transparency. Each pillar is worth 25 points for a total of 100.
Cost per effective dose is calculated using the clinically studied dose from published research, not the manufacturer's suggested serving. If a product requires multiple servings to reach the dose used in clinical trials, that cost is reflected in the value score.

Frequently Asked Questions
Is LMNT or Liquid I.V. better?
LMNT scores higher on our rubric (68 vs 57 on our 0-100 execution score) because it delivers 1000mg of sodium with zero added sugar, which suits the core purpose of an electrolyte mix - replacing the sodium lost in sweat. Liquid I.V. has less sodium and relies on added sugar for taste and its glucose transport system. Choose LMNT for endurance, low-carb, or heavy-sweat hydration; Liquid I.V. if you want a sweeter everyday drink and do not mind the sugar.
Does the added sugar in Liquid I.V. matter?
It depends on your goal. Liquid I.V. uses glucose partly to drive its co-transport hydration claim, and some sugar can aid fluid absorption during intense exercise. But for daily hydration or low-carb diets, the added sugar is an unnecessary calorie and carb load. LMNT's zero-sugar formula avoids that. If you are using electrolytes casually or on a low-carb diet, the no-sugar option is generally the cleaner choice.
