Best Electrolytes in Australia: A Buyer's Guide

The electrolyte shelf in Australia has gone from two sports drinks in a fridge to dozens of sachets, tubs and tablets, all promising much the same thing in slightly different words. Prices run from about forty cents a serve to well over two dollars, and the fronts of the packs are close to interchangeable.

This is not a ranked list of brands. It is a guide to reading the back of the pack, because that is where the differences sit. Australian electrolyte products are governed by the Food Standards Code, and once you know what the Code requires and what it leaves to the manufacturer, the label starts to make sense.

What Formulated Supplementary Sports Food actually means

Most electrolyte powders sold here carry the phrase Formulated Supplementary Sports Food somewhere on the back. It looks like a certification. It is not. It is a food category defined in Standard 2.9.4 of the Australia New Zealand Food Standards Code, in one sentence: a product that is specifically formulated to assist sports people in achieving specific nutritional or performance goals.

The status carries real obligations. Standard 2.9.4 caps a one day quantity at 70 mmol of sodium, roughly 1,600 mg, and 95 mmol of potassium, roughly 3,700 mg. It requires directions, a recommended daily intake, a nutrition information panel, and a statement that the food is not a sole source of nutrition. For a product with no added caffeine it also requires the warning statement Not suitable for children under 15 years of age or pregnant women: Should only be used under medical or dietetic supervision. And the label must not make an express or implied representation linking the food to enhanced athletic performance or beneficial physiological effects unless the Code specifically permits it.

Here is what it does not mean. It is not a Therapeutic Goods Administration listing, so there is no AUST L number attached to it, and nobody assesses an individual product against the Code before it goes on sale. It tells you the product sits inside a set of composition and labelling rules. It is not a finding that the formula works, and it is not a quality mark.

Two categories, and why it matters which one you are holding

Australia has two separate regulatory homes for these products, and they are not interchangeable. This is the part almost nobody knows, and it explains most of the confusion on the shelf.

The term electrolyte drink is a prescribed name under Standard 2.6.2, which covers non-alcoholic beverages. The Code defines one as a drink formulated for the rapid replacement of fluid, carbohydrate and electrolytes during or after 60 minutes or more of sustained strenuous physical activity. That is the regulator saying plainly what the category is for, and it is a narrower purpose than most marketing suggests. A product sold under that name, or as a powder or tablet that makes one up, has to meet a composition test:

An electrolyte drink or electrolyte drink base must contain no less than 10 mmol/L of sodium, and no less than 20 g/L and no more than 100 g/L in total of dextrose, fructose, glucose syrup, maltodextrin and sucrose.

— Standard 2.6.2, Australia New Zealand Food Standards Code

Read that second half again. A legal electrolyte drink in Australia must contain sugar, at a minimum of 20 grams per litre. That floor came down from 50 g/L after a FSANZ review of the standard, but it is still a floor.

Which is why the zero sugar products you see everywhere are not sold as electrolyte drinks. They cannot be, so they sit under Standard 2.9.4 as formulated supplementary sports foods instead. The category name is therefore a real signal: electrolyte drink tells you the product contains carbohydrate, Formulated Supplementary Sports Food usually tells you it does not. Neither is better in the abstract, but it is worth knowing which one you have picked up.

Read the per serve column, not per 100 g

Standard 1.2.8 requires a nutrition information panel to give two columns: one for a serving of the food and one for a unit quantity, which is 100 g for a powder and 100 mL for a liquid. Both columns are compulsory, and for electrolyte powders the second one is close to useless.

The reason is scale. A sachet might weigh 5 grams, so the per 100 g column is describing twenty sachets at once, and a sodium figure of 20,000 mg per 100 g sounds alarming while meaning nothing. Standard 2.6.2 goes further for electrolyte drinks and requires each electrolyte to be declared both per serving and per unit quantity, so the per serve number is always there. Use it.

Two habits make comparison honest. Check the stated serving size and the servings per pack, both of which the panel must declare, because some brands define a serve as half a sachet or half a scoop. Then check the water volume the serve is meant to go into, since the same serve in 250 mL and in 750 mL are very different drinks.

Sodium is the number that separates products

If you only compare one figure, make it sodium per serve. It is the largest point of difference between products on the Australian shelf, it varies by roughly an order of magnitude, and it is almost never on the front of the pack. The spread runs from around 100 mg per serve, common in effervescent tablets and flavoured hydration sachets, to well over 1,000 mg at the high end. Standard 2.9.4 caps a formulated supplementary sports food at 70 mmol of sodium in a one day quantity, about 1,600 mg, so a single serve product will always sit under that.

For context, the Australian and New Zealand Nutrient Reference Values set an adequate intake for adults of 460 to 920 mg of sodium a day, and a suggested dietary target of 2,000 mg for adults aged 18 and over. A 1,000 mg serve is half that target in one glass. For someone who has been sweating hard for an hour, that is the entire point of the product. It is simply a number worth knowing before you make it a daily habit, and worth raising with your doctor if you have been told to watch your sodium.

One note on arithmetic: salt and sodium are not the same figure. The panel declares sodium, and a salt figure quoted elsewhere on the pack is roughly two and a half times larger, so never compare one against the other.

Potassium and magnesium, the supporting cast

Almost every electrolyte product names potassium and magnesium on the front. Far fewer carry a meaningful amount of either, and the Code is uneven about when a brand has to back the word up with a number. For minerals with a labelling reference value there is a floor. Standard 2.9.4 allows a formulated supplementary sports food to claim a vitamin or mineral only if a serve, or the amount that makes up a normal serve for something you dilute, delivers at least 10 per cent of the reference daily intake in Schedule 1 of the Code. Magnesium's listed value there is 320 mg, so 32 mg per serve is the threshold for putting the word magnesium on the pack at all. A product sitting just above that is meeting a minimum, not making a statement.

Potassium is different, because it does not appear in that Schedule 1 mineral table at all. There is no equivalent reference value, and so no equivalent floor tied to the word. Potassium on a front of pack is not, by itself, evidence of any particular amount. Read the milligrams.

And a hydration sachet is not a substitute for a standalone magnesium supplement. The amounts sit well below what a dedicated product delivers, as we have set out in our guide to reading a magnesium label.

Sugar, sweeteners and the rest of the ingredient list

Under Standard 1.2.4, ingredients are listed in descending order of ingoing weight, so the order tells you something real. For a powder meant to be mixed with water, the Code also allows the list to be ordered by weight in the made up drink, provided the label says so. Either way, whatever sits first is the bulk of the product.

That matters because a sachet has to be made of something. If the first ingredient is dextrose or maltodextrin rather than a salt, you are buying mostly carbohydrate with electrolytes added, which is what a traditional sports drink is and not what most people picture when they buy a hydration sachet. Cross check it against the carbohydrate and sugars lines in the panel, per serve.

Additives must be declared by class name followed by the specific name or code number in brackets, which is why labels read anti caking agent (silicon dioxide) or sweetener followed by a name or a number. Intense sweeteners such as steviol glycosides and monk fruit extract appear the same way. That is a transparency rule working as intended, and an anti caking agent in a fine powder is a processing necessity rather than a red flag.

The one genuine blind spot is flavour. Standard 1.2.4 lets a flavouring substance be declared as simply flavouring or flavour, and does not require its own ingredients to be listed. So natural flavour is a legal black box, on every product on the shelf. It is not a scandal, but the ingredient list stops being fully informative at that line, and a brand willing to tell you more when asked is giving you something the label does not have to.

Cost per serve, not price per pack

Pack prices are close to meaningless here, because pack counts run from 8 to 60 and serve sizes vary with them. Divide the price by the number of servings the panel declares, which the Code requires the label to state, and you have a figure you can compare.

Then do it once more against sodium, because that is largely what you are paying for. A product at 40 cents a serve delivering 250 mg of sodium costs more per gram of sodium than one at 90 cents delivering 1,000 mg. Both are legitimate, and if a low sodium serve is what you want the first is the better buy. You just cannot tell until you compare like with like. Two things quietly change the maths: a subscription price is not the shelf price, and single sachets almost always cost more per serve than a tub.

A checklist you can take shopping

What to check	What good looks like
Category	Stated plainly, either electrolyte drink or Formulated Supplementary Sports Food, so you know whether it carries carbohydrate
Sodium per serve	Read from the per serve column in milligrams, not per 100 g, and matched to how hard you actually sweat
Serve size and water volume	Both stated, so you can compare two products on the same basis
Potassium and magnesium	Declared in milligrams per serve, not just named on the front
Sugars and carbohydrate	Per serve, and a deliberate choice rather than a surprise
Ingredient order	Salts near the front, bulking carbohydrate not doing most of the work unless you want it there
Additives	Declared by class name plus the specific substance, a short list, nothing unexplained
Required statements	Directions, daily intake and the warning statement present and legible
Value	Cost per serve, then cost per gram of sodium, not price per pack

The bottom line

Little of what is printed on the front of an electrolyte pack is regulated in a way that helps you choose. The back is. Two categories, a sodium figure per serve, the milligrams behind the mineral names, an ingredient list in weight order, and a price divided by the number of serves will separate the shelf faster than any amount of front of pack copy.

Australia has several good electrolyte products in both categories, at very different sodium levels, and the right one depends on what you are doing and how much you sweat doing it. Run the checklist across whatever is in front of you.

For transparency, Ritua Hydrate is one of them, and it is a Formulated Supplementary Sports Food rather than an electrolyte drink, which is why it carries no added sugar. Apply exactly the same checklist to it that you would to anything else on the shelf.

Frequently asked questions

What does Formulated Supplementary Sports Food mean on an Australian label?

It is a food category under Standard 2.9.4 of the Food Standards Code, defined as a product specifically formulated to assist sports people in achieving specific nutritional or performance goals. The category sets limits on sodium and potassium in a one day quantity, requires directions, a recommended daily intake and a nutrition information panel, and requires a warning statement about children under 15 and pregnant women. It is not a Therapeutic Goods Administration listing and it is not an assessment of whether a particular product works.

Why are some products called electrolyte drinks and others are not?

Electrolyte drink is a prescribed name under Standard 2.6.2, and a product using it has to meet a composition test: at least 10 mmol per litre of sodium, and between 20 and 100 grams per litre of specified sugars. A zero sugar product cannot meet that test, so it is sold under Standard 2.9.4 as a formulated supplementary sports food instead. The name on the pack is telling you which set of rules applies.

How much sodium should an electrolyte product have per serve?

There is no single right answer, and it depends on how long and how hard you are sweating. What matters when comparing is that you read the figure from the per serve column rather than per 100 g, and know what it represents. For reference, the Australian and New Zealand Nutrient Reference Values set an adequate intake of 460 to 920 mg of sodium a day for adults and a suggested dietary target of 2,000 mg. Speak to your doctor if you have been advised to limit sodium.

Why is the per 100 g column on the label so misleading?

Standard 1.2.8 requires both a per serving and a per 100 g column, and for a 5 gram sachet the per 100 g column is describing about twenty serves at once. Every number in it is roughly twenty times what you will actually drink. It is useful for comparing two powders gram for gram and useless for working out what is in your glass.

Does naming magnesium or potassium on the front mean there is much in it?

Not necessarily. For magnesium there is a floor: a formulated supplementary sports food may only claim a mineral if a serve delivers at least 10 per cent of the reference value in Schedule 1 of the Code, and magnesium's listed value is 320 mg, so the threshold is 32 mg. Potassium is not in that Schedule 1 mineral table, so no equivalent floor is attached to the word. In both cases the milligrams per serve are the only figure that tells you anything.

Are anti caking agents and sweeteners in an electrolyte powder a problem?

They are permitted food additives and have to be declared by class name plus the specific substance or its code number, which is why you see anti caking agent followed by a name in brackets. An anti caking agent is a normal necessity in a fine powder. The less transparent line is flavour, because the Code allows a flavouring to be declared as simply natural flavour without listing what is in it.
