Best Sugar-Free Electrolyte Powder: Sodium, Sweeteners and Price Compared
Love Life Supplements
Reviewed by Sarah Law, Dip CNM, Naturopathic Nutritionist
Best sugar-free electrolyte powder: for most people the best sugar-free electrolyte powder carries about 500 mg of sodium and a similar amount of potassium per serving, uses a sweetener you are happy with, and costs around a pound or a dollar a serving. On those three tests our pick is Love Life Supplements Ultimate Electrolytes: 500 mg sodium, 500 mg potassium and 150 mg magnesium per scoop, 0 g sugar, sweetened only with stevia (or nothing at all in the Unflavoured version), at £0.93 a serving on our UK store and $1.27 on our US store. If you are a heavy, salty sweater, LMNT carries twice the sodium (1,000 mg) at $1.50 a stick. Ultima Replenisher is the cheapest per serving at $0.73 but has only 55 mg of sodium, which is little more than flavoured water for sodium. And if you are training hard for more than about 90 minutes, a sugar-free powder alone is the wrong tool: you need carbohydrate too.
Our figures come from our own product data and lab report. Ultimate Electrolytes supplies 500 mg of sodium from Himalayan pink salt, 500 mg of potassium from potassium chloride (25% of the UK NRV) and 150 mg of magnesium from magnesium malate (40% of the NRV) per 5 g scoop, with 30 servings a tub and zero sugar. Lot 33447931 (Orange and Lime) was tested by Certified Group in Tustin, California, an ISO/IEC 17025 accredited laboratory, on 5 December 2025 (report 25-660895): it measured 610 mg sodium, 564 mg potassium and 165 mg magnesium per 5 g, passed the microbiology screen, and was screened for arsenic, cadmium, lead and mercury. A tub is £27.95 on our UK store (Unflavoured £24.95) and $38.07 on our US store. Verified buyers rate it 4.7 out of 5 across 211 ratings, and it is covered by our 60-day money-back guarantee.
Ultimate Electrolytes: 500 mg sodium, 500 mg potassium and 150 mg magnesium per scoop, zero sugar, stevia only, six flavours including Unflavoured.
View product- Sodium is the number to read first. Across the five powders and tablets we compared, sodium per serving runs from 55 mg (Ultima) to 1,000 mg (LMNT). Endurance athletes lose about 1,200 mg of sodium an hour in sweat on average, so a low-sodium mix replaces very little.
- Almost all of them use stevia. LMNT, Liquid I.V. Sugar-Free, Ultima, Nuun Zero Sugar and our flavoured Ultimate Electrolytes all list stevia. Liquid I.V. adds allulose. The stevia-free choices are unflavoured powders.
- "Sugar free" does not always mean zero carbohydrate. Nuun Zero Sugar has 0 g sugar but 4 g carbohydrate and 15 calories a tablet.
- Cheapest per serving: Ultima ($0.73) and Nuun Zero Sugar ($0.75). Cheapest per 500 mg of sodium: LMNT ($0.75), then ours (£0.93 or $1.27).
- For sessions over about 90 minutes, add carbohydrate from food, a gel or a sugared sports drink. A sugar-free powder gives you the minerals, not the fuel.
Best sugar-free electrolyte powder: the comparison table
The table below compares five widely sold sugar-free electrolyte products on what is in one serving, how each is sweetened and what one serving costs. Every competitor figure was read from the brand's own product page on 21 October 2026. Where a brand did not print a value in its page text, we have written "not stated" rather than guess. Prices are each brand's standard one-off price for its usual pack, before subscription discounts.
| Product (format) | Sodium | Potassium | Magnesium | Sugar / carbs | Sweetener | Price per serving |
|---|---|---|---|---|---|---|
| Love Life Supplements Ultimate Electrolytes (powder, 5 g scoop, 30 servings) | 500 mg | 500 mg | 150 mg (malate) | 0 g sugar | Stevia (steviol glycosides); Unflavoured has none | £0.93 (Unflavoured £0.83) / $1.27 |
| LMNT Recharge (powder stick, 30 per box) | 1,000 mg | 200 mg | 60 mg | No sugar | Stevia in flavours; Raw Unflavored has none | $1.50 ($1.13 in the 120-stick bundle); ships to the US and Canada only |
| Liquid I.V. Hydration Multiplier Sugar-Free (powder stick, 14 per pack in the US, 16 in the UK) | 510 mg | 380 mg | Not stated | Sold as sugar free | Allulose + stevia leaf extract (Reb A) | $1.56 ($1.09 on subscription) / £1.25 |
| Ultima Replenisher (powder, 30-serving canister) | 55 mg | 250 mg | 100 mg (citrate) | 0 g sugar, 0 g carbs | Organic stevia leaf extract (Reb A) | $0.73 ($0.53 in the 90-serving canister) |
| Nuun Zero Sugar (effervescent tablet, 10 per tube) | 200 mg | 125 mg | 20 mg (oxide) | 0 g sugar, 4 g carbs, 15 kcal | Stevia leaf extract; tapioca syrup solids | $0.75 |
Sources: drinklmnt.com, liquid-iv.com and liquid-iv.co.uk, ultimareplenisher.com and nuunlife.com product pages, read 21 October 2026. Liquid I.V. figures are from the US product page FAQ (the UK page does not print the panel in its text). Our figures are from our product data (the ingredient panels on our product page) and our live store prices. Price per serving is the pack price divided by the servings in the pack. Magnesium forms are shown where the ingredient list names them.
Two things stand out. First, the products are not interchangeable: a serving of LMNT has 18 times the sodium of a serving of Ultima. Second, "sugar free" covers three different things: no sugar listed, with nothing but minerals, acid, flavouring and stevia in the tub (ours, LMNT, Ultima), a rare sugar such as allulose that is labelled as not counting (Liquid I.V.), and a small amount of carbohydrate from a filler (Nuun). If you want to compare the full-sugar versions, our LMNT vs Liquid I.V. vs Ultimate Electrolytes comparison covers the original Liquid I.V. as well.
Which sugar-free electrolyte powder is best for you?
The best sugar-free electrolyte powder is the one whose sodium matches how much you sweat and whose sweetener you will drink every day. Here is how we would choose.
Pick by how you will use it
About 500 mg of sodium with a similar amount of potassium. Ultimate Electrolytes or Liquid I.V. Sugar-Free fit; ours adds 150 mg of magnesium and costs less per serving.
More sodium per serving. LMNT (1,000 mg) is the obvious choice in the US; elsewhere, two servings of a 500 mg powder across the session gets you to the same total.
Zero sugar. Ours and LMNT list no sugar and Ultima lists 0 g carbohydrate; Nuun Zero Sugar has 4 g of carbohydrate a tablet.
Go unflavoured: Ultimate Electrolytes Unflavoured or LMNT Raw. Our Electrolyte Balance capsules (UK store) are tasteless and contain no sweetener at all.
Ultima is the one we would steer people away from as a main electrolyte. At 55 mg of sodium per serving, you would need about nine servings to match one scoop of ours for sodium. It is a pleasant, low-mineral flavouring for water, and some people like it for exactly that reason, but it is not a sodium replacement after a sweaty session.
How much sodium should a sugar-free electrolyte have?
For most people, between 300 and 1,000 mg of sodium per serving, scaled to how much you sweat. Sodium is the electrolyte you lose most of in sweat, and it is the one that decides whether a drink helps you hold on to the water you drink.
A 2019 analysis of 1,303 athletes tested by the Gatorade Sports Science Institute found that endurance athletes lost sodium at an average rate of 51.7 mmol an hour, which is about 1,200 mg of sodium an hour, with a wide spread: one standard deviation either side runs from roughly 550 to 1,830 mg.1 A 2017 review from the same group showed how much sweat sodium varies from one person to the next and within the same person, with heat, fitness, acclimatisation and diet all playing a part.2 That is why there is no single right number for everyone.
The sodium in the drink matters for how much of it you keep. In a classic 1995 study, men who had sweated off about 2% of body mass drank the same large volume of one of four drinks that differed only in sodium. Over the next five and a half hours, the more sodium the drink held, the less urine they passed. Only the two higher-sodium drinks (52 and 100 mmol per litre, about 1,200 and 2,300 mg per litre) brought them back to fluid balance; on the low-sodium drinks they ended up 0.4 to 0.7 litres short.3 One scoop of Ultimate Electrolytes in 500 ml of water, as the label directs, gives about 1,000 mg of sodium per litre, close to the lower of the two drinks that worked in that trial.
More is not always better. If you are not sweating much, one serving a day is plenty, and most people already eat more salt than the NHS recommends. On the other side, drinking large volumes of plain water during very long events can dilute blood sodium: a study of the 2002 Boston Marathon found 13% of the runners tested at the finish had low blood sodium (hyponatraemia), and the strongest risk factors were gaining weight during the race, which means drinking more than they sweated, and a finishing time over four hours.4 Drink to thirst, and use sodium when you are sweating heavily.
Potassium and magnesium matter too, in smaller amounts. In the authorised wording used in Great Britain, potassium contributes to normal muscle function and to normal functioning of the nervous system, and magnesium contributes to electrolyte balance, to normal muscle function and to the reduction of tiredness and fatigue.5 We chose a 1:1 sodium to potassium ratio for Ultimate Electrolytes because most diets are short of potassium rather than sodium; our formula breakdown explains the reasoning.
Which sweetener is in a sugar-free electrolyte powder?
Almost always stevia. Every flavoured product in our table lists a stevia extract, and Liquid I.V. Sugar-Free pairs it with allulose. The differences between brands are less about which sweetener and more about how much flavour, acid and filler sits around it.
Stevia
Stevia sweeteners (steviol glycosides, often written as Reb A) are extracted from the leaf of the stevia plant and are many times sweeter than sugar, so only a tiny amount is used. In a 2010 trial, a stevia-sweetened preload before a meal gave lower blood glucose after eating than a sucrose preload, and lower insulin than both sucrose and aspartame.6 The common complaint is taste: some people find a liquorice-like aftertaste, which is the main reason people search for electrolytes without stevia. We explain why we chose it over sucralose and acesulfame K in zero sugar electrolytes: why stevia.
Allulose
Allulose is a rare sugar, about 70% as sweet as table sugar, with almost no calories, and US labels allow it to be left out of the "total sugars" line. A 2021 randomised crossover trial in 30 adults without diabetes found that 7.5 to 10 g of allulose taken with a 50 g sucrose drink slightly lowered the blood glucose peak at 30 minutes.7 The trial was small and several of its authors worked for an allulose manufacturer, so read it as early evidence. Larger amounts of rare sugars can upset some stomachs, so start with one serving.
Sugar alcohols and other sweeteners
None of the five products we compared uses erythritol, but some sugar-free drink mixes do. A 2023 study linked higher blood erythritol levels with a higher rate of major cardiovascular events in people being assessed for heart disease, and showed that a drink sweetened with erythritol raised blood levels for days.8 That is an association, not proof that erythritol causes harm, but it is a reason to read the ingredient list rather than the front of the pack.
Ultimate Electrolytes has six ingredients in its flavoured versions (Himalayan pink salt, potassium chloride, magnesium malate, citric acid, natural flavouring and steviol glycosides) and three in Unflavoured: the salt, the potassium chloride and the magnesium malate. There are no artificial colours or sweeteners.
"Most clients who ask me for a sugar-free electrolyte are really asking about the sweetener. The small amount of stevia in a drink mix suits most people, but a few find the aftertaste strong, and they usually get on better with an unflavoured powder stirred into water with a squeeze of lemon. The best mix is the one you will drink."

Are sugar-free electrolytes better than ones with sugar?
For everyday use, yes for most people; for long endurance sessions, not on their own. It depends on what the drink is for.
Sugar does a real job in a rehydration drink. Glucose is absorbed in the gut together with sodium, which pulls water with it, and that is why medical oral rehydration solutions contain both. In the 2016 Beverage Hydration Index trial, an oral rehydration solution (sodium plus glucose) and milk kept more of the drunk fluid in the body over four hours than water, while a standard sports drink, cola and the other everyday drinks tested did no better than water.9 In Great Britain the authorised claims that a sports drink "enhances the absorption of water during physical exercise" and helps maintain endurance performance are only allowed for carbohydrate-electrolyte solutions that supply 80 to 350 kcal per litre from carbohydrate along with set amounts of sodium.5 A sugar-free powder cannot make that claim, and we do not make it for ours.
For training, carbohydrate is fuel. Current guidance suggests small amounts of carbohydrate for sessions of about an hour, up to about 60 g an hour for two to three hours, and up to about 90 g an hour for ultra-endurance events.10 A sugar-free electrolyte supplies none of that, which is fine for a 45-minute gym session and not fine for a marathon.
For daily use, the sugar is a cost without a benefit. If you are sipping electrolytes through a working day, fasting, following a low-carbohydrate diet or simply trying to cut back on sugar, a zero-sugar powder gives you the minerals without the extra sugar a regular sports sachet carries. Our electrolytes vs sports drinks guide compares the two side by side, and electrolytes on keto and fasting covers low-carbohydrate diets.
"For a desk day or a normal gym session, a sugar-free electrolyte in a big glass of water is plenty for most people. For a long run or ride of more than about 90 minutes, I ask clients to bring some carbohydrate as well, from a banana, a gel or a sports drink, because the sugar-free mix gives you the minerals but not the fuel."

How do the electrolytes compare with UK and US daily amounts?
One serving of a 500 mg sodium powder is about a fifth of the daily sodium maximum in both the UK and the US, and a quarter of the UK reference intake for potassium. The UK and US use different reference figures, so the table shows both, each under its own name.
| Mineral | UK reference | US reference (NIH ODS / Dietary Guidelines) | One scoop of Ultimate Electrolytes | One stick of LMNT |
|---|---|---|---|---|
| Sodium | NHS: no more than 6 g salt a day (about 2.4 g sodium) | Less than 2,300 mg a day (Dietary Guidelines; FDA Daily Value 2,300 mg) | 500 mg (1.25 g salt equivalent) | 1,000 mg (2.5 g salt equivalent) |
| Potassium | NRV 2,000 mg; NHS: adults need 3,500 mg a day, and 3,700 mg or less a day from supplements is unlikely to cause obvious harm | Adequate Intake 3,400 mg (men), 2,600 mg (women) | 500 mg (25% NRV) | 200 mg (10% NRV) |
| Magnesium | NRV 375 mg; NHS: 300 mg (men), 270 mg (women); 400 mg or less a day from supplements unlikely to cause harm | RDA 400 to 420 mg (men), 310 to 320 mg (women); upper limit 350 mg a day from supplements | 150 mg (40% NRV) | 60 mg (16% NRV) |
UK: NRVs from Regulation (EU) No 1169/2011 Annex XIII as retained in GB law; NHS vitamins and minerals guidance and NHS salt guidance. US: NIH Office of Dietary Supplements fact sheets for potassium and magnesium (RDA, AI and the supplemental upper limit), and the Dietary Guidelines for Americans / FDA for sodium. Salt equivalent = sodium x 2.5.
If you take a separate magnesium supplement, add the 150 mg in a scoop of Ultimate Electrolytes to it. One scoop a day plus a 300 mg magnesium supplement already comes to 450 mg, above both the NHS 400 mg guide and the US supplemental upper limit of 350 mg.
What does a sugar-free electrolyte powder cost per serving?
Between $0.73 and $1.56 a serving on the brands' own US sites, and £0.83 to £1.25 on the UK sites we checked. Because sodium varies so much, price per serving alone can mislead, so the table also shows what each product costs for every 500 mg of sodium it delivers.
| Product | Pack and price (read 21 Oct 2026) | Per serving | Per 500 mg sodium |
|---|---|---|---|
| Ultimate Electrolytes (Love Life Supplements) | 30 servings: £27.95 (Unflavoured £24.95) / $38.07 | £0.93 (£0.83) / $1.27 | £0.93 (£0.83) / $1.27 |
| LMNT Recharge | 30 sticks: $45.00 | $1.50 | $0.75 |
| Liquid I.V. Sugar-Free | 14 sticks: $21.84 (US); 16 sticks: £19.99 (UK) | $1.56 / £1.25 | $1.53 (US) |
| Ultima Replenisher | 30-serving canister: $21.99 | $0.73 | $6.66 |
| Nuun Zero Sugar | 10 tablets: $7.49 | $0.75 | $1.87 |
One-off prices from each brand's own website; subscription and bundle prices are lower for most brands, including ours. We have not converted any currency: GBP prices are from UK sites and USD prices from US sites. Liquid I.V.'s UK page does not print a sodium figure in its text, so we have not calculated a UK cost per 500 mg.
On cost per 500 mg of sodium, LMNT is the best value in the US, because each stick carries 1,000 mg. Ours comes next, at £0.93 or $1.27. Ultima looks cheap per serving but is the most expensive way to buy sodium by a wide margin.
How we test Ultimate Electrolytes
Each flavour of Ultimate Electrolytes has a certificate of analysis on its product page, and the Orange and Lime lot below was also sent to an independent US laboratory. Certified Group in Tustin, California, accredited to ISO/IEC 17025, tested lot 33447931 and reported on 5 December 2025 (report 25-660895).
| Test (lot 33447931, Orange and Lime) | Label per 5 g | Measured per 5 g |
|---|---|---|
| Sodium (ICP-OES) | 500 mg | 610 mg |
| Potassium (ICP-OES) | 500 mg | 564 mg |
| Magnesium (ICP-OES) | 150 mg | 165 mg |
| Microbiology (total aerobic count, yeast, mould, coliforms; E. coli, Salmonella, S. aureus, P. aeruginosa) | Not on label | Counts below 10 CFU/g; pathogens absent |
| Heavy metals (ICP-MS) | Not on label | Lead 0.47 mg/kg, arsenic 0.26 mg/kg, mercury 0.04 mg/kg, cadmium not detected |
Source: Certified Group report 25-660895, linked from the Test Results section of the Ultimate Electrolytes product page. The lead result is below the 3.0 mg/kg legal maximum for food supplements in Great Britain and the EU.22
All three minerals came in above the label figure, so a scoop delivers at least what the label says. Salt from the earth carries trace metals, which is why our certificates of analysis include a heavy metal screen.
Where Love Life Supplements is not the best choice
We sell one of the products on this page, so here is where another product would suit you better.
- You sweat heavily and live in the US. LMNT gives 1,000 mg of sodium a stick and costs less per 500 mg of sodium than ours.
- You want the lowest cost per serving and do not need much sodium. Ultima and Nuun Zero Sugar both cost about $0.75 a serving.
- You are fuelling a long race or ride. A carbohydrate-electrolyte sports drink is the right tool, not a sugar-free powder (ours included).
- You want single-serve sticks for travel. Ultimate Electrolytes comes as a tub with a scoop; LMNT, Liquid I.V. and Ultima all sell sticks.
- You have been told to limit salt. Check with your doctor before using any electrolyte powder, including ours.
Who should check with a doctor before using electrolytes?
Most healthy adults can use one serving of a sugar-free electrolyte powder a day without any problem. Speak to your doctor or pharmacist first if any of these apply to you:
- You have been advised to follow a low-salt diet, or you have high blood pressure.
- You have kidney disease, because the kidneys clear excess potassium and magnesium.
- You take medicines that raise potassium, such as some blood pressure tablets (ACE inhibitors and angiotensin receptor blockers) or potassium-sparing diuretics.
- You are pregnant or breastfeeding, or you are buying for a child.
For everyone else, the practical rules are short: one serving in water on most days, a second on hot or sweaty days, and carbohydrate as well for long sessions. Our guide to drinking electrolytes every day goes into more detail.
Frequently asked questions
What is the best sugar-free electrolyte powder?
It depends on how much you sweat. For everyday use and most gym sessions, a powder with about 500 mg of sodium and a similar amount of potassium suits most people: Love Life Supplements Ultimate Electrolytes gives 500 mg sodium, 500 mg potassium and 150 mg magnesium per serving with zero sugar, at £0.93 or $1.27 a serving. For heavy, salty sweaters LMNT carries more sodium (1,000 mg). Ultima Replenisher is the cheapest per serving but has only 55 mg of sodium.
Are sugar-free electrolytes better than ones with sugar?
For everyday use, yes for most people, because you get the minerals without the sugar a regular sports sachet carries. For long endurance sessions, not on their own: glucose helps the gut absorb sodium and water, sports nutrition guidance suggests up to about 60 g of carbohydrate an hour for sessions of two to three hours, and in Great Britain the authorised hydration claim for sports drinks applies only to drinks that contain carbohydrate.
Do sugar-free electrolytes break a fast?
A powder with no sugar and no carbohydrate adds next to no calories, so for most fasting plans it does not count as breaking the fast. Check the label: some sugar-free mixes still carry a few grams of carbohydrate from fillers, such as the tapioca syrup solids in Nuun Zero Sugar (15 calories and 4 g carbohydrate per tablet).
Is Liquid I.V. Sugar-Free actually sugar free?
It is sold as sugar free. It is sweetened with allulose and stevia leaf extract, and the US ingredient list notes that allulose adds a dietarily insignificant amount of sugar. Allulose is a rare sugar with almost no calories; a small 2021 crossover trial, co-authored by staff of an allulose maker, found it slightly lowered the blood glucose rise from a sugary drink.
Is there a sugar-free electrolyte powder without stevia?
Yes. Every flavoured powder in our comparison uses stevia, so the stevia-free options are unflavoured ones: Love Life Supplements Ultimate Electrolytes Unflavoured (Himalayan pink salt, potassium chloride and magnesium malate only) and LMNT Raw Unflavored. Electrolyte Balance capsules are another option if you do not want to taste anything.
Is it safe to drink sugar-free electrolytes every day?
For most healthy adults one serving a day sits comfortably inside daily guidance: 500 mg of sodium is about a fifth of the NHS maximum of 6 g of salt (2.4 g sodium) and the US limit of 2,300 mg. Check with your doctor first if you have been told to cut down on salt, have kidney problems, or take medicines that affect potassium, such as some blood pressure tablets.
