Hydration support for training, sport and hot days

Hydration supplements are designed to make it easier to replace fluids and electrolytes around training, sport and active days. They’re especially useful when you’re sweating heavily, exercising for longer periods or simply want something more than plain water.

Formulas can be very different. Some focus on electrolytes with little or no sugar, while others include carbohydrates for longer or more demanding sessions. The right choice depends on how hard you’re training, how much you sweat and whether you want hydration alone or hydration plus extra fuel.

Electrolyte powders Easy-to-mix powders for adding electrolytes to your water bottle before, during or after training.
Hydration tablets Portable, pre-measured tablets that dissolve in water — useful for gym bags, travel and training away from home.
Low-sugar & sugar-free Choose lighter formulas when you want electrolytes without adding many extra calories or carbohydrates.
Carbohydrate hydration Some products combine electrolytes with carbohydrates for longer or more demanding sessions where you also want energy in the drink.

When hydration supplements can make sense

If you sweat a lot

Sweat contains water and electrolytes, including sodium. If you finish training drenched or regularly leave salt marks on your clothes, an electrolyte drink may be more useful than plain water alone.

If you train for longer

Longer sessions give you more time to lose fluid through sweat. Having a drink you actually enjoy sipping can make it easier to stay on top of hydration throughout the session.

If it’s hot

Heat can increase how much you sweat, whether you’re in the gym, running, cycling or training outdoors. Hydration products can be a convenient way to add electrolytes to the fluid you’re already drinking.

If you train more than once a day

When sessions are close together, staying on top of fluid intake between them becomes more important. A convenient electrolyte drink can make that easier to manage.

If you don’t enjoy plain water

A flavoured hydration drink can make your bottle more appealing, which can be useful if plain water tends to sit untouched beside you for most of the session.

If you want carbs as well

Some hydration products also contain carbohydrate, giving you fluid, electrolytes and energy in one drink. That can make more sense for longer endurance-style training than a zero-calorie electrolyte formula.

How to choose a hydration supplement

Start with sodium

Sodium is one of the main electrolytes lost in sweat and can vary significantly between hydration formulas. Compare how much is provided by the full serving rather than assuming every electrolyte product is similar.

Look at the wider electrolyte blend

Depending on the product, you may also see minerals such as potassium and magnesium. Different formulas use different combinations, so choose based on what you actually want from the drink.

Decide whether you want carbohydrates

If you’re mainly looking for hydration with minimal calories, a low-sugar or sugar-free formula may suit you. If you’re training for longer and want energy in the drink too, a carbohydrate-containing option may make more sense.

Powder or tablet?

Powders are great for regular use and can offer plenty of flavour choice. Tablets are compact, easy to carry and remove the need for measuring a scoop.

Choose a flavour you’ll actually drink

Hydration only works if you’re actually drinking the fluid. A flavour you enjoy can make it easier to keep sipping throughout a session or active day.

Think about bottle size

Different products are designed to be mixed with different amounts of water. Check the preparation instructions and choose something that works with the bottle or hydration system you normally use.

Electrolytes or plain water?

For shorter, easier sessions

Plain water may be perfectly adequate for many normal gym sessions, particularly if the session is short, the environment is cool and you’re not sweating heavily.

For longer or sweatier sessions

Electrolyte products become more relevant when fluid losses are higher, especially during long sessions, hot conditions or activities where you’re sweating heavily.

For everyday hydration

You don’t need an electrolyte supplement every time you drink water. They’re best thought of as another hydration option for the situations where the format, flavour or electrolyte content is useful to you.

For endurance training

Longer endurance sessions may call for more than fluid alone, which is why some sports drinks combine electrolytes with carbohydrates. Choose the formula based on the demands of the session rather than assuming every hydration drink serves the same purpose.

Good to know: Hydration supplements aren’t just flavoured water. They can provide electrolytes such as sodium, potassium and magnesium, while some formulas also include carbohydrates. The best choice depends on how long you train, how much you sweat and what you want from the drink.

Hydration supplement questions

What are hydration supplements?

Hydration supplements are products mixed with or consumed alongside fluid and commonly provide electrolytes such as sodium, potassium and magnesium. They’re available as powders, tablets, sachets and ready-to-drink products.

What are electrolytes?

Electrolytes are minerals that carry an electrical charge when dissolved in fluid. Sodium, potassium and magnesium are common examples found in sports hydration products.

Do I need electrolytes for the gym?

Not necessarily for every session. Water may be enough for shorter or less demanding workouts, while electrolytes can become more relevant when you’re training for longer, sweating heavily or exercising in hot conditions.

What is the difference between electrolytes and hydration drinks?

Electrolytes are minerals, while a hydration drink is the finished product you consume. Hydration supplements often contain electrolytes, but some also include carbohydrates, vitamins or other ingredients.

Do electrolyte drinks contain sugar?

Some do and some don’t. You’ll find sugar-free and low-calorie electrolyte products as well as carbohydrate-containing sports drinks designed to provide energy alongside hydration.

When should I take electrolytes?

They can be used before, during or after activity depending on the product and your routine. Many people use them during longer or sweatier sessions, but follow the directions for the individual formula.

Are hydration tablets better than powder?

Neither is automatically better. Tablets are compact and pre-measured, while powders often give you more flavour choice and can be convenient for regular use. Choose the format that best fits your routine.

Can I drink electrolytes every day?

That depends on the individual product and your overall diet and activity. Hydration supplements can fit into everyday routines, but they aren’t something everyone needs with every drink. Follow the serving guidance on your chosen product.

What should I look for in an electrolyte drink?

Look at the sodium and other electrolytes per serving, whether it contains carbohydrates or sugar, how much water it is mixed with, flavour and the format that works best for how you train.
