Q: What are electrolytes and hydration supplements?

Hydration supplements are powders, tablets and ready-to-drink formulas containing electrolytes, the charged minerals your body loses through sweat. The main ones are sodium, potassium, magnesium, calcium and chloride. Some formulas also include carbohydrates or amino acids.

Q: What is the difference between electrolytes and water?

Water replaces fluid, while an electrolyte formula replaces fluid and the minerals lost through sweat, such as sodium and potassium. For shorter or lighter sessions, water is often enough.

Q: Which hydration supplement should I choose?

It depends on how much you sweat and how you prefer to drink it. Heavy sweaters and endurance athletes often choose a higher sodium formula, while a lighter daily formula suits general use. Powders offer the most value per serve, tablets and sachets are easiest to carry, and ready-to-drink formulas need no mixing.

Q: Do I need electrolytes if I only train for an hour?

For most sessions under an hour in mild conditions, water is generally sufficient. Electrolytes become more useful as sessions get longer, as conditions get hotter, or if you are a heavy sweater and notice salt marks on your training gear.

Q: Can I take a hydration supplement every day?

Many people use a lighter electrolyte formula daily to help meet their fluid intake, particularly in summer or in physically demanding jobs. Follow the serving instructions on the label, and speak with your doctor first if you have a health condition affecting sodium or fluid intake.

Q: Are there sugar-free electrolytes?

Yes. Many electrolyte powders are sugar free, such as Hydrate Perform (Sugar Free) by Switch Nutrition. Check the nutrition panel for sugar and carbohydrate per serve.

Q: Do electrolyte drinks contain caffeine?

Most don't, but some do, such as Hydrate + Caffeine by Switch Nutrition. Check the label, and count the caffeine if you also take a pre-workout or drink coffee.

Q: Are electrolyte tablets or powders better?

Both contain electrolytes, so it comes down to convenience. Tablets are easy to carry and drop into a bottle, while powders usually offer more serves for the price and a wider range of flavours.

Q: Can I mix electrolytes with my pre-workout or aminos?

Many people add electrolytes to a training bottle with amino acids. Some prefer to take them separately from a pre-workout so they can control each one. Follow the directions on each label.

Q: Where can I buy electrolytes in Australia?

You can buy electrolytes and hydration supplements online at Nutrition Warehouse with free shipping over $150, or in-store at over 120 locations with same-day Click & Collect.

Electrolytes Buying Guide

Shop electrolyte powders, tablets, sachets and ready-to-drink hydration from Dr. Hydrate, Genetix Nutrition, Sodii, Pillar Performance and Switch Nutrition.

Last Updated: Wednesday 28th October 2026

What Are Electrolytes and Hydration Supplements?

Electrolytes and hydration formulas replace the fluid and minerals you lose through sweat. When you train hard or train in the heat, water alone does not always keep up, and an electrolyte supplement helps you stay on top of both.

Electrolytes are charged minerals involved in fluid balance, nerve signalling and normal muscle function. The main ones lost through sweat are sodium, potassium, magnesium, calcium and chloride. Hydration supplements, also called electrolyte supplements or hydration formulas, are powders, tablets and ready-to-drink products designed to put those minerals back alongside the fluid you have lost.

At Nutrition Warehouse, we stock electrolytes from Dr. Hydrate, Genetix Nutrition, Sodii, Pillar Performance, Switch Nutrition, Science in Sport and more. Want to see which ones customers rate highest? Check out our Top 10 Electrolytes.

Key Electrolytes and What They Do

Sodium: the electrolyte lost in the largest amount through sweat, and central to fluid balance
Potassium: works alongside sodium and contributes to normal muscle function
Magnesium: contributes to normal muscle function and energy metabolism
Calcium: involved in muscle contraction
Chloride: supports fluid balance alongside sodium

Looking for magnesium on its own? Shop our full magnesium supplements range.

Types of Electrolyte Supplements

Electrolytes come in a few different formats. Here's how they compare:

Type	What it is	Example
Electrolyte powders	Mix into a bottle, usually the best value per serve, in a wide flavour range	Hydration Drink Mix (Jar) by Dr. Hydrate
Electrolyte sachets	Single-serve sticks or sachets for your bag or desk	Everyday Hydration Salts (Sachets) by Sodii
Electrolyte tablets	Drop into water, easy to carry in a gym bag or race belt	Hydro Tablet by Science in Sport
Ready to drink	No mixing required, useful mid-session or on the go	Sparkling Electrolyte Hydration RTD by Pillar Performance
Electrolytes with caffeine	Electrolyte powders with added caffeine	Hydrate + Caffeine by Switch Nutrition

Electrolyte levels vary by product, so always check the label for sodium, sugar and caffeine per serve.

When to Use an Electrolyte Supplement

Electrolyte supplements are most useful when fluid loss is high. Common situations include:

Long or high-intensity sessions: anything over an hour, where sweat loss adds up
Training in heat or humidity: Australian summers push sweat rates well above normal
Endurance events: running, cycling, triathlon and team sports with extended play. Browse our running supplements and energy gels
Everyday use: some people use a lighter formula through the day to help meet their fluid intake

How to Choose the Right Hydration Formula

Sodium per serve: higher sodium formulas suit heavy sweaters, hot conditions and long endurance efforts, while lighter daily formulas suit general use.
Sugar and carbs: choose a sugar-free formula for everyday use, or one with carbohydrate for longer sessions.
Caffeine: some electrolyte formulas contain caffeine, so check the label if you also take a pre-workout.
Format: powders for value, sachets and tablets to carry, or ready-to-drink cans and bottles.
Flavour: a formula you enjoy drinking is one you'll actually finish.
