Top 9 Best Electrolyte Powder for Endurance & Performance (2026)
01 · Best overall✓ Label verified · Supplement Facts read Sep 7, 2026Best overall: LMNT Zero Sugar Electrolytes — Citrus Salt, 30 Stick Packs
The high-sodium benchmark: 1000 mg sodium per stick is multiples of what mainstream mixes deliver, making it the default pick for keto, fasting, and heavy-sweat training where salt is the limiting electrolyte.
$45$1.50 / stick
Why it wins: all five scores, pros & cons, full label
- 1000 mg sodium per serving — the category's high-salt anchor for keto/fasting/endurance
- Zero sugar, stevia-sweetened, no artificial colors or flavors
- Balanced 200 mg potassium + 60 mg magnesium alongside the high sodium
- Highest cost per serving of mainstream picks (~$1.50/stick)
- The deliberately salty taste is polarizing for some first-time users
- Sodium
- 1000 mg per stick
- Potassium
- 200 mg per stick
- Magnesium
- 60 mg per stick
- Sugar
- 0 g sugar
- Sweetener / form
- Stevia leaf extract; powder stick packs (no artificial sweeteners)
Our take — LMNT is the category benchmark because it solves the problem most mixes ignore: it actually delivers sodium, 1000 mg per stick, several times what mainstream hydration powders give you. Pair that with a clean zero-sugar, stevia-sweetened formula and a sensible 200 mg potassium plus 60 mg magnesium, and it's the default for anyone on keto, fasting, or sweating hard. You pay the most per serving and the salty taste polarizes newcomers — but if sodium is what you're actually short on, nothing here competes.

- ~810 mg per stick
- Potassium
- ~400 mg per stick
- Magnesium
- 60 mg per stick (plus 60 mg calcium)
All five scores, pros & cons, full label
What We Like- High ~810 mg sodium with a 4-electrolyte spread (adds calcium vs. salt-only mixes)
- Real Salt source contributes 60+ trace minerals; zero sugar, stevia-sweetened
- Often cheaper per serving than LMNT while still salt-forward
What You Live With- Stevia + Real-Salt mineral taste reads as salty/earthy to some users
- Single-flavor stick boxes; this listing is Mango specifically
- Sugar
- 0 g sugar
- Sweetener / form
- Stevia leaf extract; powder stick packs (60+ trace minerals from Real Salt)
Our take — Redmond Re-Lyte is the pick for buyers who want LMNT's salt-forward philosophy with a fuller mineral spread: ~810 mg sodium, ~400 mg potassium, plus calcium and 60+ trace minerals from Real Salt, all at zero sugar and usually a little cheaper per serving than LMNT. The trade-off is a stevia-plus-mineral taste that reads earthy to some, and this listing is Mango only. For a complete, high-sodium electrolyte profile rather than a salt-only hit, it's the best all-rounder here — and our premium choice.
- 03
Best budget (zero-sugar): Key Nutrients Electrolyte Recovery Plus Powder Packets — Refreshing Lemonade, 20 Packets
7.8SAC Score™The budget zero-sugar pick: a 6-electrolyte formula bundled with vitamins at a low cost per serving and made in the USA, for value-focused buyers who want a no-sugar everyday mix.

What We Like- Zero sugar, zero calories with a full 6-electrolyte + vitamin/mineral blend
- Low cost per serving; made in the USA, gluten-free
- Bulk canister versions available for even cheaper per-serving cost
What You Live With- Listing leads with the multivitamin angle; per-electrolyte mg amounts are less prominent on the label
- Sodium is moderate — not a salt-forward keto/endurance formula
- Sugar
- 0 g sugar (no calories)
- Sweetener / form
- Stevia (no sugar, no calories); powder packets (6 electrolytes + vitamins)
Our take — Key Nutrients is the value play: a zero-sugar, zero-calorie 6-electrolyte mix bundled with vitamins at roughly $0.85 a packet, made in the USA, with even cheaper bulk canisters available. It's the cheapest credible no-sugar everyday option here. The honest caveats are that the listing leads with its multivitamin angle and is less forthcoming about per-electrolyte mg, and the sodium is moderate rather than salt-forward. For a budget daily zero-sugar mix it's the best-priced pick; for keto/endurance salt loads, spend up for LMNT or Redmond.
- 04
Best magnesium-forward (sugar-free): Ultima Replenisher Daily Electrolyte Powder — Original Variety Pack, 20 Stick Packs
7.5SAC Score™The magnesium-forward, sugar-free pick: low sodium but a strong 100 mg magnesium plus potassium and calcium — ideal for everyday hydration and for users who specifically want minerals without the salt load.
StrongestClean formula9.52WeakestSodium & electrolyte dose4.0- Sodium
- ~55 mg per stick

What We Like- Sugar-free and zero-calorie with a notably high 100 mg magnesium per serving
- Full 6-electrolyte profile plus zinc and vitamin C; vegan, keto-friendly, non-GMO
- Variety pack lets buyers sample flavors at a low cost per serving
What You Live With- Very low sodium (~55 mg) — not suited to heavy-sweat or keto-salt needs
- Stevia sweetness is divisive for some palates
- Sugar
- 0 g sugar (zero calorie)
- Sweetener / form
- Organic stevia leaf; powder stick packs (6 electrolytes + zinc & vitamin C)
Our take — Ultima is the sugar-free, mineral-rich everyday option for people who specifically don't want a salt load: a strong 100 mg magnesium, 250 mg potassium and calcium across a full 6-electrolyte profile, all zero-sugar and zero-calorie. The catch is the headline electrolyte — at ~55 mg, its sodium is far too low for heavy sweat or keto salt replacement. If you want minerals and magnesium for daily hydration rather than salt for hard training, it's an excellent fit; if you're sweating buckets, look to the top of this list.
- 05
Best clean label: Cure Hydration — Hydrating Electrolyte Mix — Lemonade, 14 Packets
7.5SAC Score™The clean-label, plant-based pick: an ORS-inspired formula built on coconut-water potassium and sea salt with no added sugar and no artificial or stevia sweeteners — for buyers who want a 'real food' ingredient list.

What We Like- Plant-based, no added sugar, and free of artificial sweeteners and stevia
- Potassium-forward via real coconut water powder; FSA/HSA eligible
- Short, recognizable ingredient list for clean-label shoppers
What You Live With- Lower sodium (~240 mg) — light for heavy-sweat or keto salt needs
- Premium cost per packet for a 14-count pouch
- Sugar
- No added sugar (small amount naturally from coconut water / fruit)
- Sweetener / form
- No stevia or artificial sweeteners — real fruit & coconut water; powder stick packets
Our take — Cure is the clean-label answer for buyers who want a 'real food' ingredient list: sodium from sea salt, potassium from actual coconut water, no added sugar and — unusually — no stevia or artificial sweeteners either. It's potassium-forward and genuinely minimalist. The cost is a lower ~240 mg sodium that's light for heavy sweating or keto, and a premium price on a small 14-count pouch. If a short, recognizable ingredient list matters more to you than maximal salt, it's the pick.
- 06
Best for magnesium + immunity: Trace Minerals Power Pak Electrolyte Powder Packets — Raspberry, 30 Packets
7.4SAC Score™The mineral/immunity-loaded pick: 200 mg magnesium and 1200 mg vitamin C plus 70+ ConcenTrace trace minerals per packet, for buyers who want hydration paired with a high-magnesium, immune-support boost.

What We Like- High 200 mg magnesium plus 1200 mg vitamin C and zinc for recovery/immune support
- 70+ full-spectrum trace minerals from ionic sea minerals; balanced sodium + potassium
- Long-established mineral brand; many flavors and canister options
What You Live With- Contains ~5 g cane sugar — not zero-sugar or strict keto
- Mixes into a small 4–6 oz volume; concentrated, tart taste isn't for everyone
- Sugar
- ~5 g sugar (cane sugar)
- Sweetener / form
- Cane sugar with citric acid; powder packets (1200 mg vitamin C, zinc, 70+ trace minerals)
Our take — Trace Minerals Power Pak is the mineral-and-immunity option: a big 200 mg magnesium, 1200 mg vitamin C, zinc, and 70+ trace minerals on top of balanced sodium and potassium, from a long-established brand. It's effectively a hydration-plus-recovery shot. The downsides are ~5 g of cane sugar (so not keto or zero-sugar) and a concentrated, tart mix in a small 4–6 oz volume that won't suit everyone. If you want electrolytes bundled with a high-magnesium, immune-support hit, it earns its spot; for clean salt replacement, look to the salt-forward picks at the top of this list.
- 07
Best taste (real-fruit): Skratch Labs Hydration Sport Drink Mix — Lemon & Lime, 20 Servings
7.0SAC Score™The athlete's real-food taste pick: light real-fruit sweetness and a small amount of cane sugar to fuel working muscles during exercise, with a clean ingredient list endurance athletes favor over heavily-flavored mixes.
StrongestTaste & mixability9.81WeakestFull mineral spectrum5.5- Sodium
- ~380 mg per serving

What We Like- Real-fruit flavor with no artificial sweeteners/colors — widely praised taste
- Light, drinkable sweetness with functional carbs for endurance efforts
- Vegan, non-GMO, gluten- and dairy-free; trusted endurance-sport brand
What You Live With- Contains real cane sugar — not zero-sugar or strict keto
- Low potassium and modest sodium; tuned for taste/light fueling, not max electrolytes
- Sugar
- ~4 g sugar (real cane sugar; glucose + fructose for working muscles)
- Sweetener / form
- Real cane sugar and real fruit (no artificial sweeteners); powder (resealable bag)
Our take — Skratch Labs is the taste pick, and endurance athletes know it: light real-fruit flavor, a small amount of cane sugar to fuel working muscles, and a clean ingredient list with no artificial sweeteners or colors. It's the mix you'll actually enjoy on a long ride. The trade-offs are that it isn't zero-sugar or keto, and it's tuned for palatable light fueling rather than maximal electrolytes — potassium in particular is low. For training-day taste and gentle carbs, it's excellent; for salt replacement, it's mid-pack.
- 08
Best for rehydration (ORS): DripDrop ORS Electrolyte Hydration Powder Sticks — Berry, 32 Sticks
6.9SAC Score™A doctor-developed oral rehydration solution (ORS): the precise sodium-to-glucose ratio targets fast rehydration with about 3x the electrolytes and half the sugar of typical sports drinks — best for sickness, heat, and acute dehydration.
StrongestValue per serving8.53WeakestClean formula6.0- Sodium

What We Like- Medically-styled ORS ratio for rapid rehydration (illness, heat, hard efforts)
- More electrolytes and less sugar than a standard sports drink; adds zinc + vitamin C
- Small 8 oz mix volume and portable single sticks
What You Live With- Contains ~7 g sugar/glucose — not a zero-sugar or strict-keto option
- Moderate sodium; built for rehydration ratio, not maximal salt replacement
- Sugar
- ~7 g sugar (glucose, ORS ratio)
- Sweetener / form
- Glucose (functional ORS sodium-glucose cotransport) + stevia; powder stick packets
Our take — DripDrop is the pick for acute rehydration rather than everyday topping-up: a doctor-developed ORS whose deliberate sodium-to-glucose ratio is built to pull fluid in fast when you're sick, overheated, or wrung out from a hard effort. That ~7 g of glucose is the mechanism, not a flaw — but it does rule the product out for strict keto or zero-sugar goals, and the sodium is tuned for the rehydration ratio rather than maximal salt replacement. For a sick day or a brutal heatwave, it's the right tool.
- 09
Most popular (mainstream): Liquid I.V. Hydration Multiplier — Lemon Lime, 16 Servings
6.7SAC Score™The mainstream, widely-recognized hydration pick: its Cellular Transport Technology pairs sodium with glucose for fast fluid uptake — best for general daily/everyday-dehydration use rather than zero-sugar diets.

What We Like- Best-known, easy-to-find brand with a glucose-driven fast-absorption formula
- Includes a B-vitamin + vitamin C blend on top of the electrolytes
- Non-GMO, gluten/soy/dairy-free; pleasant, well-reviewed flavors
What You Live With- 11 g of added sugar per packet — disqualifying for keto, fasting, or sugar-free goals
- Sodium is moderate (~500 mg), far below dedicated high-salt mixes
- Sugar
- 11 g sugar (cane sugar + dextrose)
- Sweetener / form
- Cane sugar / dextrose (functional for absorption); powder stick packets
Our take — Liquid I.V. is the brand most people already know, and its glucose-paired formula genuinely drives fast fluid uptake — useful for everyday dehydration, travel, or a rough morning after. But you have to be honest about what it is: an 11 g sugar drink. That sugar is functional for absorption, yet it disqualifies the product for keto, fasting, or anyone cutting sugar, and the ~500 mg sodium is moderate next to the dedicated salt mixes. Great mainstream everyday pick; wrong tool for a zero-sugar goal.
The Guide In Four Short Lessons
Read the sodium per serving first.
Sodium is what you lose most in sweat. Serious mixes deliver about 1000 mg a serving; many 'hydration' mixes hand you 50 to 250 mg.
Check the sugar.
Some best-known products carry about 11 g of added sugar per packet. That sugar helps absorption, but it rules the mix out for keto, fasting or cutting sugar.
Ask whether you need one at all.
Most people eating normally are covered by food and water. These mixes earn their place for heavy sweaters, keto or fasting protocols, endurance athletes and work in real heat.
Framing backed by 5 peer-reviewed PubMed sources on sodium, sweat losses and rehydration: ACSM position stand (Sawka 2007, PMID 17277604), Baker 2017 (PMID 28332116), Sharp 2006 (PMID 16772634), Shirreffs 1996 (PMID 8897383) and the 3rd hyponatremia consensus (Hew-Butler 2015, PMID 26227507). Nine most-purchased Amazon powders scored on sodium & electrolyte dose (30%), clean formula (25%), full mineral spectrum (20%), value per serving (15%), and taste & mixability (10%) — full scoring in the methodology below.
Electrolyte powders look interchangeable on the shelf and behave nothing alike in the glass, so we weighted the thing that actually separates them: sodium and total electrolyte dose, at 30%. This is decisive because sodium is the electrolyte you lose most and the one mixes most often skimp on — a powder with real content (LMNT's ~1000 mg, Redmond's ~810 mg) earns the points; a token 50–250 mg sprinkle does not, no matter how many electrolytes the label lists. Clean formula is next at 25%, and here we're deliberately honest about the sugar-bombs: a zero- or low-sugar mix with no artificial colors or junk scores high, while a product that's effectively a sugar drink (Liquid I.V. at 11 g, the ORS-style mixes at 5–7 g) gets marked down for anyone outside its rehydration use-case. Full mineral spectrum is worth 20% — we credit a genuine potassium-and-magnesium profile alongside the sodium, because a complete electrolyte spread beats a salt-only or magnesium-only formula for most buyers. Value per serving is the 15% tiebreaker, ranging here from under $1 to about $1.50 a serving. Taste and mixability rounds it out at 10%, the lowest weight because it's the most personal axis — but it's the difference between a tub you finish and one that stalls. Every sodium, potassium, magnesium and sugar number below is from the real product label; nothing was invented, and no third-party certification was claimed for any product because none was recorded.
Sodium & electrolyte dose · 30%
The decisive axis. Sodium is the electrolyte you lose most in sweat and deplete fastest on keto or fasting, and it's the one mixes most often under-dose. We reward real content — LMNT's ~1000 mg and Redmond's ~810 mg per serving anchor the top — and penalize token 50–250 mg amounts dressed up with a long electrolyte list. Total electrolyte load counts, but sodium leads.
Clean formula · 25%
Zero or low sugar and no artificial colors, flavors or junk. We're blunt about the sugar-bombs here: Liquid I.V. (~11 g) and the ORS-style mixes (5–7 g glucose) score down for everyday, keto and fasting use even where that sugar is functional for absorption. Stevia and real-fruit sweetening with 0 g added sugar score highest; cane-sugar and dextrose formulas score lowest unless rehydration is the explicit goal.
Full mineral spectrum · 20%
Potassium and magnesium alongside the headline sodium. A complete electrolyte spread — and useful extras like calcium or trace minerals — beats a salt-only or magnesium-only formula for most buyers. We credit a genuine potassium-and-magnesium dose; a powder that nails sodium but ignores the rest, or pads magnesium while starving sodium, loses ground here.
Value per serving · 15%
Real cost per stick or scoop, which runs from under $1 to about $1.50 a serving across this lineup. Judged against what the serving actually delivers — a high-dose salt-forward stick and a budget everyday mix are scored on different value propositions, not just the raw number. The tiebreaker between picks of similar substance.
Taste & mixability · 10%
How it tastes and how cleanly it dissolves — the daily-compliance factor. Lowest weight because it's the most personal axis, and because a deliberately salty high-sodium mix is polarizing by design. But the best electrolyte powder is the one you'll actually reach for on a hot day, so flavor and clean mixing still count.
How electrolytes work
- 1
Sodium holds the water
Sodium is the main extracellular electrolyte: it sets fluid balance, blood volume and nerve drive. Sweat loses 500-1,500 mg per hour — plain water after heavy sweating dilutes what is left, which is why you can drink and still fade.
- 2
Potassium balances the cell
Inside the cell, potassium partners with sodium to keep the gradient that muscles and nerves fire on. Cramping, flatness and heart-flutter feelings under heat often trace to this pair, not to willpower.
- 3
Magnesium runs the enzymes
Hundreds of enzymatic reactions — including muscle relaxation — need magnesium; sweating and low intake drain it. A modest daily dose in the mix quietly supports what the loud minerals get credit for.
- 4
Dose honesty decides everything
The category splits into real formulas (500-1,000 mg sodium per serving) and flavored water (100 mg and vibes). Sugar is a legitimate co-transporter for endurance racing, unnecessary for a desk day — we scored both honestly.
What to expect from proper electrolytes
The heavy-sweat fix
After a sauna, hot training session, or long fast: a real sodium dose restores sharpness and kills the woozy, flat feeling within the hour. If you were not depleted, you will taste salt and feel nothing — that is honest.
Fewer cramps, better sessions
Training in heat with a 500 mg+ sodium mix, expect fewer cramps and steadier late-session output. Keto and fasting users typically feel the biggest lift — carb restriction dumps sodium fast.
Calibration
Match dose to sweat: salty-sweater marks on dark shirts mean the high-sodium picks; light days need half a stick. Chronic over-salting a sedentary day buys nothing — scale with output.
Situational, not superstition
Keep it for sweat, heat, fasting and illness. With normal food and mild activity your kidneys manage fine — the honest limit most brands will not print.
The bottom line
LMNT (#1) is the high-sodium benchmark.
At ~1000 mg sodium per stick with zero sugar, plus sensible 200 mg potassium and 60 mg magnesium, it's the default for keto, fasting and heavy-sweat training where salt is the limiting electrolyte. You pay the most per serving (~$1.50/stick) and the salty taste polarizes newcomers, but if sodium is what you're short on, nothing here competes.
Past #1, match the tool to the job.
Redmond Re-Lyte (#3) is the premium all-rounder, adding calcium and 60+ trace minerals to ~810 mg sodium; Key Nutrients (#8) is the cheapest credible zero-sugar daily mix at about $0.85 a packet. Liquid I.V. (#2) absorbs fast but is an 11 g sugar drink; Ultima (#4) is magnesium-forward sugar-free; DripDrop (#5) is a doctor-developed ORS for acute rehydration; Cure (#6), Skratch Labs (#7) and Trace Minerals Power Pak (#9) cover clean label, taste and magnesium-plus-immunity.
Buy for your actual sodium need — and skip it when you don't need it.
Most people eating a normal diet do not need one every day; these mixes are for a specific job (heavy sweat, keto/fasting, endurance, heat), and even then sodium is what usually matters, not the length of the electrolyte list. The page was blunt about the sugar-bombs (Liquid I.V. at 11 g, ORS mixes at 5–7 g) and claimed no third-party certification for any product because none was recorded.
Quick Answers
Which pick is the best overall?
Zero Sugar Electrolytes — Citrus Salt, 30 Stick Packs by LMNT is our #1 pick (SAC score 8.9/10). LMNT is the category benchmark because it solves the problem most mixes ignore: it actually delivers sodium, 1000 mg per stick, several times what mainstream hydration powders give you. Pair that with a clean zero-sugar, stevia-sweetened formula and a sensible 200 mg potassium plus 60 mg magnesium, and it's the default for anyone on keto, fasting, or sweating hard. You pay the most per serving and the salty taste polarizes newcomers — but if sodium is what you're actually short on, nothing here competes.

The ACSM's authoritative position stand on hydration: the goal is to begin exercise euhydrated with normal plasma electrolyte levels, to limit fluid deficits, and — because sweat contains substantial sodium — to include sodium in fluids during prolonged exercise and recovery to offset losses and stimulate thirst and fluid retention. The foundational evidence that electrolyte (especially sodium) replacement, not water alone, matters when sweat losses are large.
- [2] Baker 2017 PMID 28332116 — Sweating Rate and Sweat Sodium Concentration in Athletes: A Review of Methodology and Intra/Interindividual Variability. A review documenting that athletes lose water and electrolytes through thermoregulatory sweating, and that both sweating rate and sweat sodium concentration vary widely within and between individuals. The basis for the page's core point — heavy sweaters can lose large, person-specific amounts of sodium, which is exactly the gap a high-sodium electrolyte mix is meant to fill.
- [3] Sharp 2006 PMID 16772634 — Role of sodium in fluid homeostasis with exercise. A review of the interactive effects of sodium and fluid ingestion in maintaining fluid balance during and after heat and exercise. Heavy sweating can produce fluid deficits of 1–8% of body mass, and including sodium chloride in the replacement beverage is recommended to maintain fluid homeostasis and reduce the risk of hyponatremia from over-drinking plain water during efforts longer than four hours.

In a controlled rehydration trial, both the volume consumed and the drink's sodium content interacted to determine fluid recovery: a drink volume greater than sweat loss must be ingested to restore balance, but unless the beverage's sodium content is sufficiently high, the extra fluid is simply lost as urine. Direct experimental evidence for why sodium — not just water — is the limiting electrolyte for effective rehydration.

The honest counterweight on this page: more is not better — electrolyte (sodium) balance, not maximal fluid intake, is what protects endurance athletes, and most casual exercisers don't need aggressive supplementation at all.
