Best Electrolyte Powders in 2026, by Evidence

Last verified November 2, 2026. Every label figure, certification and price on this page links to the page we checked. Labels change, so check yours before you rely on a number here.

We have not tested these products ourselves; label figures come from the retailer and brand pages cited below, and lab results come from the named testers.

The short answer

Most people don't need an electrolyte drink. Water and normal meals cover a typical workout. Sodium starts to matter when you sweat heavily for a long time: hot sessions, long runs and rides, or two sessions a day. How much you lose varies widely from person to person.³ The bigger risk in long events is drinking too much plain water, not too little salt.²

• Heavy, salty sweater in long or hot sessions: a high-sodium mix such as LMNT (1,000 mg) or Redmond Re-Lyte (810 mg).⁷¹⁵
• Endurance sessions over about an hour where you also want carbs: a mix with sugar, such as Precision Fuel & Hydration PH 1000 or Skratch.¹³¹⁴
• Vomiting or diarrhea: an oral rehydration solution built on the WHO formula, with sodium and glucose in set amounts.¹ DripDrop is the closest of these products.¹²
• High blood pressure or kidney disease: talk to your clinician first. One LMNT stick holds 1,000 mg of sodium, two-thirds of the AHA's 1,500 mg ideal daily limit for most adults.⁷⁴

Status snapshot: what the labels and marks mean

Electrolyte mixes are sold as foods or dietary supplements. The FDA does not check them before sale. A few carry an independent mark for banned-substance testing.

Product	Independent mark we could cite	Note
LMNT	Informed Choice6	Not listed with NSF Certified for Sport or Informed Sport, per the registry.
Nuun Sport	Informed Choice6	Lemon Lime checked.
Redmond Re-Lyte Hydration	Informed Choice6	Strawberry Lemonade checked.
Liquid I.V. Hydration Multiplier	None found6
DripDrop	None found6	Sold as an ORS-style drink. That is a formulation claim, not a certification.
Ultima Replenisher	None found6
Precision Fuel & Hydration, Skratch	Not covered by the registry we used	Check the brand and certifier directly.

*Certifications come from a third-party registry, not the certifier's own directory, which we could not reach. Confirm before you rely on it for drug testing.

Who actually needs sodium

Sweat rate and sweat sodium differ a lot between people, and they change with heat, fitness and acclimatization.³ Two athletes doing the same session can lose very different amounts of salt. That is why one product can't suit everyone.

• Probably not needed: sessions under about an hour in mild conditions, with normal meals before and after.
• Worth considering: long sessions in the heat, multi-hour endurance events, two-a-day training, or if you see white salt marks on your clothes. Replacement is about matching what you lose, not maxing sodium.³
• Not a fix for overdrinking: the 2015 consensus statement says exercise-associated hyponatremia is mainly caused by drinking more than you sweat, and that sodium in drinks does not prevent it if you overdrink. It recommends drinking to thirst.²

A sweat test (a patch test at a lab or sports clinic) is the only way to know your own sweat sodium. Weighing yourself before and after a session shows your fluid loss: each kilogram lost is about a liter of sweat.

Evidence map: graded by use

A = strong guideline or consistent trials. B = good support in a narrower group. C = plausible, limited direct evidence. D = no good evidence. X = evidence of harm.

Use	Grade	What the evidence says
Rehydration in diarrhea (oral rehydration solution)	A	WHO and UNICEF recommend a reduced-osmolarity ORS (245 mOsm/L). Compared with the older formula, it cut unscheduled IV therapy in children by about 33%, stool output by about 20% and vomiting by about 30%.1 Sports mixes are not the same formula.
Replacing sodium in long, sweaty exercise	B	Sweat sodium losses can be large in some athletes and vary widely, so replacement makes sense for heavy, salty sweaters in long sessions.3
Preventing exercise-associated hyponatremia	D	The consensus statement found sodium supplements do not prevent it when people overdrink. Drinking to thirst is the main prevention.2
Everyday "hydration" for people who aren't sweating much	D	We found no trials showing a benefit over water and food.
High-sodium drinks with high blood pressure	Xcaution	The AHA advises no more than 2,300 mg of sodium a day and an ideal limit of 1,500 mg for most adults.4
Potassium supplements with kidney disease	Xcaution	People with kidney disease can build up too much potassium. NIH advises talking to a clinician before taking potassium.5

Our picks and how we chose them

We set these criteria before we looked at any product. Commission is not one of them.

1. The sodium, potassium and sugar per serving are on a label we could check.
2. The formula fits a specific use (heavy sweating, endurance with carbs, illness, or low-sodium daily use).
3. We could cite an independent banned-substance mark, or we say clearly that we couldn't.
4. Cost per serving at a named retailer on November 2, 2026.
5. No proprietary blend that hides electrolyte amounts.

Some links on MoveWell earn us a commission. That played no part in which products are listed here or in what order.

Heavy sweaters, no sugar: LMNT

1,000 mg sodium, 200 mg potassium and 60 mg magnesium per stick, with no sugar.⁷ Informed Choice, per the registry.⁶ About $1.50 a stick. It is a lot of sodium for a sedentary day. Our LMNT review has more on the product.

Lower-cost high sodium: Redmond Re-Lyte Hydration

810 mg sodium, 400 mg potassium, 50 mg magnesium and 60 mg calcium per scoop, with 0 g sugar. 30 scoops for $27.21, about $0.91 per serving.¹⁵ Informed Choice, per the registry.⁶

Long endurance sessions with carbs: Precision Fuel & Hydration PH 1000

500 mg sodium and 16 g sugar per sachet. PF&H designs it for 500 ml, which works out to 1,000 mg of sodium per liter, the number in the name; the retailer listing says 16 oz (473 ml), which is slightly saltier.¹³ About $1.75 a sachet. PF&H sells several strengths, so you can match the dose to your sweat test.

Lighter endurance option: Skratch Sport Hydration

400 mg sodium, 40 mg potassium and 19 g sugar in 12–16 oz of water.¹⁴ $1.95 for a single packet; tubs cost less per serving. Better for moderate sweaters than for very salty ones.

Illness and travel: DripDrop

330 mg sodium, 180 mg potassium and 7 g sugar per stick, mixed in 8 oz (237 ml).¹² That is about 1,390 mg sodium per liter, closer to the WHO ORS than most sports mixes (WHO ORS: 75 mmol/L sodium, about 1,725 mg per liter).¹ About $1.00 a stick. For a child or for severe or ongoing diarrhea, use a pharmacy ORS and call a clinician.

Low-sodium daily use: Ultima Replenisher

Only 55 mg sodium, with 250 mg potassium and 100 mg magnesium, and no sugar or calories.¹⁶ $20.99 for 20, about $1.05 a stick. Not enough sodium for heavy sweating. Its magnesium counts toward the 350 mg supplement limit in our magnesium guide.

Cheapest per serving: Nuun Sport

300 mg sodium, 150 mg potassium, 25 mg magnesium and 1 g sugar per tablet.¹⁰¹¹ About $0.65 a tablet. Informed Choice, per the registry.⁶

For context, sweat sodium varies with heat, fitness, heat acclimation, diet, sex and age, and with how it is measured.³ Compare the per-liter column with your own sweat test, not with an average.

Products we held or excluded

• Liquid I.V. Hydration Multiplier: in the table but not a pick. It costs more per serving than our picks, has 11 g of added sugar, and we found no independent mark.⁸⁹⁶ Prices vary a lot by store.
• Sugar-free versions of several brands exist. We compared the flagship formula of each.
• Thorne, Transparent Labs and BUBS electrolytes carry NSF Certified for Sport, per the registry. We did not check their labels or prices for this update.

How to choose

• Start with the session, not the brand. Short or cool: water. Long and hot: sodium. Long and hard: sodium plus carbs.
• Compare sodium per liter, not per stick. A small stick in a small glass can be saltier than a big stick in a big bottle.
• Count the sugar. Sugar helps during long efforts and in ORS. For desk days, it is just extra sugar.
• Check magnesium if you also take a magnesium supplement. Ultima has 100 mg, LMNT 60 mg.
• Drug-tested? Look for NSF Certified for Sport or Informed Sport, and check the certifier's own directory.

Safety and who should be careful

Situation	What to know
High blood pressure	AHA: no more than 2,300 mg sodium a day, ideally 1,500 mg for most adults. The AHA notes the ideal limit may not fit people who lose a lot of sodium in sweat, such as competitive athletes and workers in heavy heat.4 High-sodium mixes can use most of a 1,500 mg budget in one serving.
Kidney disease	Potassium and magnesium can build up. Ask your clinician before using any electrolyte supplement.5
Heart failure or a fluid limit	Follow your care team's fluid and sodium plan, not a product label.
Drugs that raise potassium (some blood pressure drugs, potassium-sparing diuretics)	NIH notes these can raise potassium. Ask your clinician before adding potassium.5
Long endurance events	Don't drink beyond thirst. Overdrinking causes hyponatremia even with salty drinks.2
Children with diarrhea or vomiting	Use a pharmacy ORS and call a clinician.1

Myths

Myth	What the evidence says
"Everyone should drink electrolytes daily."	We found no evidence of benefit for people who aren't losing much sweat.
"Salt tabs prevent hyponatremia."	The consensus statement says hypotonic sodium-containing sports drinks "will not prevent EAH in athletes who overdrink". Drinking to thirst is the main prevention.2
"More sodium is always better."	Needs vary several-fold between people.3 Too much adds to your daily sodium.4
"A sports drink is the same as ORS."	ORS uses a set ratio of sodium to glucose for diarrhea.1 Most sports drinks don't match it.

FAQ

Do I need electrolytes after a normal workout?

Usually not. Water and your next meal replace what an hour of moderate exercise uses.

How much sodium should I take during long exercise?

It depends on your sweat rate and sweat sodium, which vary widely.³ A sweat test gives you a personal number. Many endurance mixes are built around 500–1,000 mg per liter.¹³

Is LMNT too much sodium?

For a heavy sweater in the heat, maybe not. For a desk day, one stick is 1,000 mg, two-thirds of the AHA's 1,500 mg ideal limit.⁷⁴

LMNT vs Liquid I.V.: which is better?

They do different jobs. LMNT has about twice the sodium and no sugar. Liquid I.V. has 11 g sugar and more potassium.⁷⁸ See the table above.

Can electrolyte drinks help with a hangover or illness?

For vomiting or diarrhea, an ORS helps you rehydrate.¹ We found no good trials on hangovers.

Are sugar-free electrolytes worse?

Not for everyday use. Glucose helps sodium absorption, which is why ORS contains it, and sugar adds fuel for long efforts.¹
