A Simple Guide to Electrolytes & Hydration

Electrolytes are minerals that play an important role in the body's normal functions. They are found naturally in foods and drinks, and they are also available in electrolyte powders, tablets and drinks.

But what exactly are electrolytes, why do people use them, and what should you look for when choosing an electrolyte supplement?

In this guide, we'll explain electrolytes in simple terms and look at how they can fit into an everyday hydration routine.

What are electrolytes?

Electrolytes are minerals that carry an electrical charge when dissolved in fluid.

The main electrolytes include:

  • Sodium

  • Potassium

  • Magnesium

  • Calcium

  • Chloride

These minerals are naturally present in the body and are also found in a variety of foods and drinks.

Because electrolytes are associated with fluid balance and normal bodily functions, they have become increasingly popular in hydration drinks and supplements.

Why are electrolytes important?

Your body needs a balance of fluids and minerals to function normally.

Sodium and potassium, for example, are electrolytes involved in normal body processes, while magnesium contributes to normal muscle function and normal functioning of the nervous system.

This is one reason electrolytes are commonly included in hydration products.

However, an electrolyte supplement isn't a replacement for a varied, balanced diet. Most people can obtain the nutrients they need through a healthy diet, with supplements providing a convenient option in certain circumstances.

Where do electrolytes come from?

Electrolytes are naturally found in many foods.

For example:

Sodium can be found in salt and many everyday foods.

Potassium is found in foods including bananas, potatoes, beans and vegetables.

Magnesium is found in foods such as nuts, seeds, wholegrains and leafy green vegetables.

Calcium is found in dairy products and a range of other foods.

You can therefore get electrolytes from your normal diet as well as from drinks and supplements.

What are electrolyte drinks?

Electrolyte drinks are beverages containing one or more electrolytes.

They come in several forms, including ready-to-drink beverages, tablets and powders that are mixed with water.

Electrolyte powders have become particularly popular because they are convenient to keep at home, in a gym bag, at work or when travelling.

What is electrolyte powder?

Electrolyte powder is simply a powdered formulation containing electrolytes and, depending on the product, other ingredients such as vitamins or amino acids.

The powder is mixed with water before consumption.

When choosing an electrolyte powder, it's worth looking beyond the word "electrolytes" on the front of the pack and checking the full ingredient and nutrition information.

What should you look for in an electrolyte powder?

Not all electrolyte products are formulated in the same way.

Here are some things worth considering when comparing products.

1. Which electrolytes are included?

Check which electrolytes the product actually contains and the amount provided per serving.

Sodium, potassium and magnesium are commonly found in electrolyte formulations.

2. How much sugar does it contain?

Some electrolyte drinks contain added sugar, while others are formulated without added sugar.

If this matters to you, check the nutrition information and ingredient list rather than relying solely on front-of-pack marketing.

3. What other ingredients are included?

Some products contain additional vitamins, minerals or other ingredients.

Consider the complete formulation rather than focusing on one ingredient in isolation.

Can you take electrolytes every day?

Whether you need an electrolyte supplement every day depends on your individual diet, lifestyle and circumstances.

Electrolytes are already present in a normal balanced diet, so supplementation isn't automatically necessary for everyone.

If you choose to use an electrolyte supplement, always follow the product's recommended serving instructions and read the label carefully.

If you have a medical condition, take medication, are pregnant or breastfeeding, or have any concerns about using a supplement, speak to an appropriate healthcare professional before taking it.

Electrolytes and everyday hydration

Water is essential for everyday hydration, and drinking enough fluids throughout the day is an important part of a healthy lifestyle.

Electrolyte products offer another option for people who want to include electrolytes as part of their hydration routine.

This can be particularly convenient when you're looking for something beyond plain water, whether you're at work, travelling, exercising or simply getting on with a busy day.

The bottom line

Electrolytes are minerals that are naturally found in the body and in many foods and drinks.

Sodium, potassium, magnesium and calcium are some of the key electrolytes, and they are involved in a range of normal bodily functions.

You don't necessarily need an electrolyte supplement simply because you exercise or drink water, but electrolyte products can provide a convenient way to include electrolytes as part of your routine.

When choosing an electrolyte powder, look at the complete formulation, nutrition information, ingredients, serving size and sugar content rather than focusing on one feature alone.
