Best Electrolytes in Australia 2026: An Honest Comparison From a Store That Sells All of Them

The short answer: there is no single best electrolyte powder in Australia, because the brands are built for different sodium levels and different people. LMNT and Sodii sit at 1,000mg of sodium per serve. SALTT sits at 969mg with much higher potassium and magnesium. Redmond Re-Lyte sits at 810mg and costs the least per serve of the high-sodium options. Ultima Replenisher sits at 55mg, for people who want the other minerals without much salt. Below is every number side by side, taken from each brand's own nutrition panel, plus an honest view of who each one actually suits.

We are LYTES, a family business in Unanderra, NSW. We have been selling electrolytes since 2021 and we stock all of these brands. That means we have no reason to push you toward one over another. We would rather you buy the right one once than the wrong one twice, because the second outcome usually ends with a half-used tub in the back of a cupboard and a customer who does not come back.

What actually separates one electrolyte powder from another?

Strip away the branding and there are only four variables that matter.

• Sodium per serve. This is the biggest difference between brands, and the range is enormous: from 55mg to 1,000mg. Sodium is the mineral you lose most of in sweat, so the right number depends entirely on how much you sweat.
• Potassium and magnesium. Present in every brand, but in very different amounts. Some formulas are built around a sodium-heavy profile, others spread the load more evenly.
• Sweetener and flavour. Stevia, monk fruit or unflavoured. This is the single most common reason people switch brands, and it is completely subjective.
• Cost per serve. Box price is misleading because serving counts vary from 30 to 90. Per-serve cost is the only fair comparison.

How do the main brands compare on paper?

Every figure below is per single serve, taken from the manufacturer's own published nutrition information.

Prices are LYTES prices in AUD at the time of writing and are for the standard flavoured product in each range. Re-Lyte's unflavoured version runs higher at 1,000mg sodium per serve. Ultima also contains 47mg calcium and 70mg phosphorus per serve. Re-Lyte adds 1,280mg chloride. Always check the pack, because manufacturers reformulate.

How much sodium do you actually need?

This is the question that decides everything else, and the honest answer is that it depends on your sweat rate, not on a brand's marketing.

Sweat is salty. The more you sweat and the longer you sweat for, the more sodium leaves your body. Someone doing a two-hour ride in a Queensland summer is losing a very different amount to someone sitting in an air-conditioned office in Melbourne in July. Sodium losses in sweat vary a lot between individuals, which is exactly why the market has settled into two broad tiers rather than one universal number.

A practical way to think about it:

• Long sessions, heat, heavy sweating, physical trades, endurance training. The 800mg to 1,000mg range is what these products were designed for.
• Everyday use, light activity, air-conditioned work, or you simply do not like salty drinks. The lower-sodium end of the market exists for exactly this, and there is nothing wrong with sitting there.
• Somewhere in between. Half a stick in a full bottle is a completely legitimate way to use a high-sodium product. Plenty of our repeat customers do this.

If you have been told to watch your sodium intake, talk to your GP or dietitian before adding any of these to your routine. That is not a legal disclaimer for its own sake, it is genuinely the right order to do things in.

Which brand suits which person?

LMNT

The one most Australians have heard of, and the one that made high-sodium electrolytes mainstream. 1,000mg sodium, 200mg potassium, 60mg magnesium, zero sugar, no artificial colours. Flavours are bold and unapologetically salty, which people either love immediately or need a few goes to get used to. There are eleven flavours in the Australian range plus four variety packs, and the Raw Unflavoured version is popular with people who want to add it to something else. At $64.95 for 30 sticks it is not the cheapest, but it has the widest flavour range and the most consistent reorder rate of anything we stock.

Best for: heavy sweaters who want a flavour range to rotate through, and anyone who wants the product they have already read about.

Redmond Re-Lyte

810mg sodium, 400mg potassium, 50mg magnesium and 1,280mg chloride per serve, built on Redmond's unrefined Real Salt. The tub format is what makes it stand out commercially: 60 serves for $74.95 works out at $1.25 a serve, the lowest of the higher-sodium options. The trade-off is that you are scooping rather than tearing a stick, so it is a kitchen-bench product more than a gym-bag one.

Best for: daily users who go through a lot of it and want the per-serve cost down, and anyone who prefers a less sweet profile.

Sodii

Australian made, 1,000mg sodium, 210mg potassium, 70mg magnesium. The formulation sits in the same tier as LMNT, so the decision between them usually comes down to flavour preference and whether buying locally made matters to you. For a lot of our customers it does.

Best for: people who want a locally made product at the higher end of the sodium range.

SALTT

969mg sodium, but with 415mg potassium and 178mg magnesium, which is a noticeably different mineral spread to the rest of the high-sodium tier. If you have looked at the other panels and thought the potassium and magnesium numbers seemed small next to the sodium, this is the formula built for that view.

Best for: people who want a high-sodium product without the rest of the minerals being an afterthought.

Ultima Replenisher

The outlier, and deliberately so. 55mg sodium, 250mg potassium, 100mg magnesium, 47mg calcium, 70mg phosphorus, sweetened with stevia and coloured with plant extracts rather than synthetic dyes. Ninety serves for $89.95 is $1.00 a serve, the cheapest on this list. It is a completely different product to the rest and should be judged on its own terms.

Best for: everyday hydration, people who find salty drinks unpleasant, and anyone who wants the other minerals without much sodium.

What does each one cost per serve?

Box price is the number people compare, and it is the wrong one. Ultima looks like the most expensive product on the shelf at $89.95 and is actually the cheapest per serve at $1.00. Re-Lyte looks dearer than LMNT at $74.95 and works out $0.92 a serve cheaper because you get twice as many serves.

The order, cheapest to dearest per serve: Ultima at $1.00, Re-Lyte at $1.25, LMNT at $2.17, SALTT at $2.23, Sodii at $2.30.

Worth saying plainly: the gap between the top and bottom of that list is about $1.30 a day. For most people that is not the deciding factor. Whether you actually enjoy drinking it is.

So how do you actually choose?

After 42,000 orders, the pattern we see is boring but consistent. People do not switch brands because they read a better nutrition panel. They switch because they did not like the taste of the first one they bought, and a 30-serve box is a lot of servings to get through when you are not enjoying it.

So our honest advice is to taste before you commit. That is not a sales line, it is the single thing that best predicts whether someone is still using electrolytes three months later.

Frequently asked questions

What is the best electrolyte powder in Australia?

There is no single best one. LMNT, Sodii and SALTT sit near 1,000mg of sodium per serve and are built for heavy sweating. Re-Lyte sits at 810mg and costs the least per serve in that group. Ultima sits at 55mg for people who want the other minerals without much sodium. Choose based on your sweat rate and your taste preference.

Which electrolyte has the most sodium?

LMNT and Sodii both declare 1,000mg of sodium per serve, the highest of the brands compared here. SALTT is close behind at 969mg.

Is more sodium always better?

No. The right amount depends on how much you sweat. High-sodium products were designed for long sessions, heat and physical work. For light everyday use, a lower-sodium option or a half serve of a high-sodium one is often a better fit.

Are any of these made in Australia?

Sodii is Australian made. LMNT, Redmond Re-Lyte, SALTT and Ultima Replenisher are imported. All of them ship to you from our warehouse in Wollongong, NSW, so delivery times are the same regardless of where the product was manufactured.

Do electrolyte powders contain sugar?

The five compared here are all sugar free. They use stevia, monk fruit or similar sweeteners instead, and unflavoured versions are available in several of the ranges.

How many can I have per day?

Follow the directions on the pack, which vary by brand. If you are unsure how these fit with your own diet or health circumstances, check with your GP or an accredited practising dietitian.

Not sure which one is yours?

Try four brands side by side instead of guessing at a full box.
