This article discusses dietary supplements and is for general information only — it is not medical advice. Electrolyte products are concentrated sources of sodium and other minerals, which can interact with certain medications and health conditions, including high blood pressure. Talk with your doctor or a registered dietitian before adding one to your routine.

The best electrolyte powder for most people is LMNT Recharge. It delivers 1,000 mg of sodium per serving for $1.50. That’s the lowest cost per 1,000 mg of sodium among the three brands here — LMNT, Nuun Sport, and Liquid I.V. Hydration Multiplier. Nuun Sport flips that ranking over a full year. At one serving a day, it’s the cheapest electrolyte powder to use daily — $273.75 a year. Most people don’t need LMNT’s full 1,000 mg dose every single day anyway.
I’ve done hurricane-season cleanup work in Gulf Coast heat, the kind where plain water alone doesn’t cut it past the first hour or two outside. A shirt crusted white with dried salt by early afternoon is a decent clue. Your body needs more sodium than tap water alone is giving it.
Liquid I.V. is the weakest value of the three. It costs the most per 1,000 mg of sodium delivered, and carries up to 11 grams of added sugar. Which of the other two wins depends on how much sodium you actually lose through sweat. Heavy training and low-carb diets favor LMNT’s per-milligram price. Everyday hydration favors Nuun’s lower total cost.
The Sodium-Per-Dollar Table, Before Any Interpretation
Price, sodium, sugar, and the cost-per-1,000-mg-of-sodium figure are what this comparison is built around. We verified each one directly against the brand’s own product page and nutrition panel this week.
| Electrolyte powder | Price per serving | Sodium per serving | Sugar per serving | Cost per 1,000 mg sodium |
|---|---|---|---|---|
| LMNT Recharge | $1.50 ($1.13 on the 120-stick bundle) | 1,000 mg | 0 g | $1.50 |
| Nuun Sport Electrolyte Tablets | $0.67–$0.75 | 300 mg | 1 g | $2.50 |
| Liquid I.V. Hydration Multiplier | $1.56 (~$1.09 on subscription) | ~500–560 mg | up to 11 g | $2.79 |
The arithmetic is simple: price per serving divided by (sodium per serving ÷ 1,000). LMNT’s $1.50 for 1,000 mg comes out even. Nuun’s $0.75 for 300 mg scales to $2.50 per 1,000 mg. Liquid I.V.’s $1.56 for roughly 560 mg scales to about $2.79 per 1,000 mg — the worst ratio of the three. It also carries the most sugar.
The One-Year Cost of a Daily Habit
All three brands are effectively subscription products in practice — one serving a day empties a box or tube on a predictable schedule. Here’s one year (365 servings) at both list price and each brand’s cheapest published bulk or subscription price.
| Electrolyte powder | Cost per year (list price) | Cheapest published price/serving | Cost per year (cheapest) |
|---|---|---|---|
| Nuun Sport | $273.75 | $0.67 (sale price) | $244.55 |
| LMNT Recharge | $547.50 | $1.13 (120-stick bundle) | $412.45 |
| Liquid I.V. Hydration Multiplier | $569.40 | ~$1.09 (subscription) | $397.85 |
Prices are approximate, current as of publication, and change frequently — confirm the latest price with the retailer before buying.
Nuun’s own site doesn’t list a standing subscription discount at checkout. Its list price already beats both competitors’ subscription prices anyway. That’s the whole reason it wins the annual column despite losing the per-milligram one.
Do You Need an Electrolyte Powder at All, or Is Water Enough?
For most people on most days, plain water is enough. Emily Paonessa, RDN, a clinical dietitian quoted in Forbes Health’s review of Liquid I.V., put it directly: “For most people, water is sufficient for adequate hydration. This product, if used daily, could put someone over their added sugar and sodium needs.” Physician guidance compiled by NBC Select makes a related point. Water alone “doesn’t cut it” for strenuous exercise, physically demanding jobs, or long stretches in the heat. Those are the situations where a supplemental product earns its cost. Most healthy adults can safely drink one serving daily if they choose to. But daily use is a habit these products are priced around — not a requirement any of them impose.
An electrolyte powder earns its cost in a few specific situations. Workouts or outdoor work lasting over an hour. Heavy sweating in heat. Illness with vomiting or diarrhea. Low-carb or keto diets that flush sodium faster than typical eating patterns. Outside of those, a daily electrolyte habit is mostly paying for minerals a normal diet and tap water already supply.
Best Electrolyte Powder by Use Case
Endurance training, heavy sweat, and low-carb diets: LMNT Recharge is the strongest fit. Its 1,000 mg sodium dose matches expert guidance for prolonged intense activity, and it contains zero sugar. At $1.50 per 1,000 mg of sodium, it’s the cheapest way in this comparison to replace sodium at that scale. Sports dietitian Kelly Jones told NBC Select: “For those with very high sweat rates, I often suggest incorporating LMNT to aid in rehydration and maintaining energy levels during exercise.”
Casual daily hydration: Nuun Sport fits best — light workouts, hot commutes, or just drinking more water with some flavor and minerals attached. Its 300 mg dose covers moderate activity without excess, and its added sugar is negligible at 1 gram. Its $273.75 annual cost undercuts both alternatives by more than $100.
Occasional recovery, not daily use: Liquid I.V.’s added vitamin C and B vitamins make it a reasonable pick after heat exposure, illness, or a hard workout. Eleven grams of sugar matters less as a once-in-a-while drink than as a 365-day habit. Pediatric clinical dietitian Lindsey Donovan, RDN, told Forbes Health she likes that “the ingredients are naturally sourced and contain electrolytes close to their most simple form.” Skip it for daily use specifically because of the sugar load and the worst cost-per-sodium ratio of the three. LMNT’s sugar-free formula is the common substitute when sugar is the concern.
Dealbreakers Worth Knowing
LMNT Recharge: the highest one-time price per dose ($1.50), and 1,000 mg of sodium is more than most casual users need. Check with a doctor before regular use if you have high blood pressure or a related condition.
Liquid I.V. Hydration Multiplier: up to 11 grams of added sugar per serving and the highest cost per 1,000 mg of sodium delivered ($2.79). It’s also the least sodium-efficient of the three for anyone training hard.
Nuun Sport: at 300 mg of sodium per tablet, it isn’t enough on its own for marathon-length or extreme-heat sweat loss without doubling the dose. It also doesn’t publish a subscription discount the way its two competitors do.
All three: none of these replace medical guidance for conditions involving sodium restriction, kidney disease, or heart conditions. Kelly Jones’s general advice, per NBC Select, applies across the category. Avoid products with unnecessary artificial coloring or flavoring. Check whether a brand discloses third-party lab testing before assuming its purity claims — elite athletes specifically need NSF Certified for Sport or Informed Sport certification if drug testing applies to them.
Sourcing: Brand Product Pages and Dietitian-Reviewed Guides
We checked current prices and nutrition facts against each brand’s own product pages — LMNT, Liquid I.V., and Nuun — this week. We cross-checked sodium guidance and expert framing against NBC Select’s dietitian-sourced roundup, Forbes Health’s review of Liquid I.V., and BarBend’s review of Liquid I.V.’s label. Every figure and expert quote here comes from those published sources, named throughout. Read more about how we work on our editorial standards page.
