There are four completely different kinds of product sitting under the words electrolyte drink, and they are not interchangeable. Buy the wrong one for your training and you will either be drinking sugar you did not plan for, or salt you do not need.
This guide sorts them out. What you actually lose in sweat, how to read a label properly, what separates the four product types on an Australian shelf, and where each one is genuinely the right answer. Including the cases where UCAN is not.
Contents
Sweat is not water. Five minerals leave with it, in roughly this order of quantity.
| Mineral | Roughly how much you lose per litre of sweat | Why it is on the label |
|---|---|---|
| Sodium | 400 to 1,800 mg, varies enormously between people | By far the largest loss, and the one every product leads with |
| Chloride | Tracks sodium closely | The other half of common salt. Often not declared separately, which is a clue about the formula |
| Potassium | 150 to 250 mg | Contributes to normal muscle function. Losses are far smaller than sodium, so the doses are smaller too |
| Magnesium | Small, but it adds up across a long training week | Contributes to normal muscle and nerve function. The mineral most often left out entirely |
| Calcium | Small | The second mineral most products skip |
Two numbers vary so much between individuals that no product can be right for everyone out of the box. Sweat rate in trained athletes commonly runs 0.8 to 1.5 litres per hour, and climbs past two litres in Australian summer humidity. Sweat sodium concentration ranges roughly four-fold. That is why the useful skill is reading a label, not picking a brand.
Every product on an Australian shelf falls into one of these four. Work out which category you need before you compare brands inside it.
| Type | Typical sodium per litre | Carbohydrate | Best for | Wrong for |
|---|---|---|---|---|
| Traditional sports drinks Gatorade, Powerade | 400 to 460 mg | 50 to 60 g of sugar per litre | Anyone who wants fluid and fuel from the same bottle and is not counting either | Anyone already taking gels, because the carbohydrate stacks up unplanned |
| Salt forward mixes LMNT, Sodii | 1,000 to 2,000 mg | Usually none | Very salty sweaters, ultra distance in heat, anyone who has done a sweat test and knows they lose a lot of salt | Drinking across three hours. Most people find that concentration hard to keep taking |
| Rehydration products Hydralyte | Varies, formulated as an oral rehydration solution | Contains sugar by design, which is how the formulation works | Illness and fluid loss outside sport, which is what they are made for | Training. They are not built as a session drink |
| Zero carbohydrate powders UCAN Hydrate, Nuun | 600 to 660 mg for UCAN Hydrate | None | Athletes whose carbohydrate already comes from gels or powder, daily hydration, hot weather, rest days | Anyone expecting the bottle to also fuel them. It will not |
The honest read on that table: if you have done a sweat test and know you are a heavy salt loser, a salt forward mix does that job better than anything else and you should buy one. If your carbohydrate is already sorted and you want minerals without touching your fuelling maths, a zero carbohydrate powder is the category. If you have not planned your fuel at all, a traditional sports drink is doing two jobs adequately and one of them badly.
Five checks, in this order. Most product pages will only volunteer the first one.
The internet argues about 1,000 mg an hour. Most published guidance for endurance events lands lower, between 300 and 600 mg of sodium per hour, with the top of that range for heavy or salty sweaters in heat.
The number that matters is your own, and you can measure it over one long run with a set of bathroom scales. The full protocol, plus how to add up the sodium already sitting in your gels, is in the guide to hydration for marathon training. Do that before you spend money on any of these products.
Zero carbohydrate powder category. Formulated by an Olympic dietitian, sweetened with stevia leaf extract, eight ingredients. Here is the full specification, read from the current pack labels.
| Per 3 g serve in 500 ml | Amount | Per litre |
|---|---|---|
| Sodium | 300 to 330 mg by flavour | 600 to 660 mg |
| Chloride | 150 mg | 300 mg |
| Potassium | 100 mg | 200 mg |
| Magnesium | 50 mg | 100 mg |
| Calcium | 20 mg | 40 mg |
| Carbohydrate | 0 g | 0 g |
| Energy | 0 calories | 0 calories |
Sodium is the only thing that changes between the four flavours. Lemon Lime 300 mg, Watermelon and Berry 310 mg, Pineapple 330 mg. Everything else is identical, and the jar and the sticks carry exactly the same 3 g serve, so choose the flavour on taste and the format on where you drink it.

Northern hemisphere hydration advice assumes you race in the cold and build in autumn. Australians do the opposite, so most of it arrives with the seasons inverted.
| Conditions | What to change |
|---|---|
| Hot and dry Adelaide, Perth | Sweat evaporates fast, so you feel less wet and drink less than you should. Set a schedule instead of drinking to thirst. |
| Hot and humid Darwin, Brisbane, Cairns | Sweat drips rather than evaporating, so you lose fluid with no cooling benefit. This is where the highest hourly targets apply. |
| Variable Melbourne, Hobart | Two numbers rather than one. Run the sweat test twice, once cool and once warm, and use whichever matches the day. |
| Altitude Snowy Mountains, Blue Mountains | Faster breathing means more fluid lost through respiration, and cool air hides it. Keep drinking on schedule even when you do not feel hot. |
| 5 am starts, any city | An early start does not remove the need. Humidity is often highest just after dawn. |
One practical detail worth more than any of the above: freeze half your bottle overnight and top it with water in the morning. People drink noticeably more when it stays cold.
| When | What to do |
|---|---|
| 20 to 30 minutes before | One serve in 500 ml of cold water. Matters most before early starts and hot afternoon sessions. |
| Sessions under 60 minutes | In cool conditions, water is enough. In summer heat, one serve is worth having. |
| 60 to 120 minutes | One serve every hour to hour and a half, adjusted to your sweat rate and the day. |
| Past two hours | Keep the same rhythm rather than increasing volume late. Small amounts often beats large amounts occasionally. |
| After | Around 1.2 to 1.5 litres for every kilogram lost, spread across four to six hours rather than drunk in one go. |
| Rest days in summer | One serve a day is reasonable. There is no carbohydrate in it, so it costs you nothing nutritionally. |
If you are drinking for more than 90 minutes at a time or backing up long sessions on consecutive days, there is a version with six amino acids added, covered in the guide to amino acids for endurance athletes. For everything shorter, standard Hydrate is the simpler and cheaper choice.
Electrolytes are one of three decisions, and the easiest one. The other two are how much carbohydrate you take per hour, and in what format. Both are covered on the marathon, triathlon and running pages.
Where they intersect is worth knowing. UCAN Edge gels carry 50 mg of sodium each, and the Edge + Electrolyte version carries 200 mg, which counts toward your hourly total. Three of the four Energy Powder flavours carry 130 to 170 mg. Add them all up before you decide what goes in the bottle. The carbohydrate in all of them is LIVSTEADY, and the comparison against sugar based fuel is set out in sugar based vs sugar free energy gels.
The mistake worth avoiding is spending $54.90 on 30 serves of a flavour you cannot drink at hour three. Every Hydrate flavour is available as a single sachet for $2.50. Test one on a real long run before you commit.
Decide first whether you want carbohydrate in the bottle, because that splits the market in half. Then convert sodium to a per litre figure so you can compare brands with different serve sizes. Then check whether magnesium and calcium are in the formula at all, and finally check the sweetener, because that is what determines whether you can still drink it at hour three.
One to three serves is a reasonable range depending on how much you train, how hot it is and how much you sweat. In Australian summer, one serve a day on rest days is normal for people training regularly. Because it carries no carbohydrate and no kilojoules, it does not affect anything else you are eating.
Better is the wrong frame. They do different jobs. A sports drink is trying to be your fluid and your fuel at once, which works if you have no other fuelling plan. If your carbohydrate is already coming from gels or powder, a sports drink adds carbohydrate you did not plan for and cannot easily measure. That is when a zero carbohydrate option is the right call.
If you have done a sweat test and know you lose a lot of salt, yes, and salt forward mixes are built for exactly that. They carry two to three times the sodium of UCAN Hydrate. The trade is drinkability across a long session, which is why some athletes carry a high sodium mix for the first hour and something lighter after that.
Coconut water carries useful potassium but very little sodium, which is the mineral you lose most of. It also carries natural sugars. It is a pleasant drink and it is not a training electrolyte solution, which is a different thing.
Yes. An eight ingredient electrolyte powder with no carbohydrate mixes with protein powders, amino acids and most other performance products without complicating anything. The reason it is easy to combine is precisely that it carries nothing but minerals and flavour.
All four are the same formula except for sodium, which runs from 300 mg on Lemon Lime to 330 mg on Pineapple. So the decision is taste, not formulation. Pineapple is the one to reach for on the hottest days. Buy a $2.50 sachet before you buy a $54.90 jar.
Identical formula and the same 3 g serve. The jar is around a third of the price per serve and lives at home. The sticks travel, fit a race belt and dose accurately without a scoop. Most people training seriously end up with both.
Nutrition figures read from current Australian pack labels. Competitor figures from published nutrition panels and dosing guidance, correct as at August 2026. Guidance here is general and not individual advice. Sweat rate and sweat sodium concentration vary widely between individuals and change with heat, humidity and fitness. Adjust from here based on your own testing.
