Electrolyte Water: Benefits and Myths

In the world of wellness, electrolyte water has become one of those buzzwords you hear everywhere... from gym bottles to supermarket shelves. But what is it, really? And more importantly, is electrolyte water good for you, or is it another health fad riding on clever marketing?

This blog gently walks you through the benefits, the myths, and what to keep in mind if you're curious about hydration with electrolytes, especially if you're over 40, feeling a little more tired than usual, or just looking for smarter ways to support your daily wellbeing.

Let’s start with the basics. 

Electrolytes are essential minerals like sodium, potassium, magnesium, and calcium—that help regulate fluid balance, nerve signals, and muscle function. 

Without enough of them, the body can feel a bit “off,” whether that means fatigue, light-headedness, or muscle cramps. When the body is seriously depleted it can contribute to more serious health problems. 

You lose electrolytes when you sweat, go to the loo, or experience illness. That’s why they matter—not just during intense workouts, but also as we age or deal with daily stress.

So why electrolyte water instead of just... water?

Plain water is great for basic hydration, but in some situations—like a hot summer day, a bout of the flu, or after a long walk—you may need more. That’s where hydration with electrolytes comes in.  If the body is seriously depleted then they may need to regularly take additional electrolytes to restore balance. 

Electrolyte water is simply water with added minerals. It can help replenish what your body loses and may support steadier energy, better focus, and easier recovery when you’re feeling depleted.

Some people also prefer it when doing intermittent fasting, following low-carb diets, or as part of active ageing routines, especially if they notice signs of electrolyte imbalance symptoms, such as fatigue, cramps, or brain fog.

Sometimes, water alone doesn’t quite hit the spot... especially after a sweaty walk, a tummy bug, or even just a long day outdoors. Electrolyte water may help your body absorb and retain fluids more effectively, making you feel rehydrated faster without needing to gulp litres all at once.

If you’ve ever felt a little foggy or sluggish, it might not always be from tiredness, it could be mild dehydration or low electrolyte levels. Topping these up can help some people feel more clear-headed, more focused, and less drained, especially during warm weather or after being active.

You don’t need to be running marathons to feel the effects of physical exertion. Even gardening, walking the dog, or doing the weekly shop can leave you needing to replenish. Electrolyte water may help your body bounce back more smoothly by supporting fluid balance and muscle function.

Let’s be honest, not everyone enjoys the taste of plain water. If that’s you, lightly flavoured or naturally enhanced electrolyte drinks can be a useful way to make hydration feel easier (and a bit more exciting). It’s about finding what works for you.

And remember, the best electrolyte water in the UK doesn’t have to be a bright-coloured sports drink packed with sugar. Natural options are often simpler and just as effective—think coconut water, electrolyte powders with clean ingredients, or even filtered water with a squeeze of citrus and a pinch of sea salt. It can be that straightforward.  Salt is the most natural electrolyte and adding it to water is a great option. Always use a natural sea salt or Himalayan salt. For best results use a deep sea salt, because of the mineral balance, including trace minerals. 

We've noticed that there is a lot of confusion online, so let’s clear up a few common myths about electrolyte water:

Not necessarily! Most people eating a balanced diet and staying moderately active don’t need added electrolytes every day. However few people eat a balanced diet so there is frequently a need for mineral supplementation. Plain filtered water  with alkaline minerals often does the job. However If you are drinking reverse osmosis filtered water or distilled water which strip everything from the water it is essential to supplements with mineral electrolytes. 

Too much of anything can be unhelpful. Overdoing electrolyte drinks, especially high-sodium ones, can throw your balance off. Listen to your body and stay mindful.

Many commercial sports drinks are high in sugar, artificial flavourings, or unnecessary additives. Electrolyte water can be a cleaner, simpler alternative, depending on the brand or mix you choose.  It is vitally important not to consume sugars or sugar substitutes in your water. 

If you're wondering if electrolyte water is good for you, the answer depends on your lifestyle. 

You might benefit from adding it to your routine if you:

• Are physically active or exercise regularly
• Spend time in the sun or heat
• Are over 50 and noticing new energy dips or dehydration signs
• Follow a low-carb or fasting-based diet
• Are recovering from illness or feeling run down
• If you are struggling with a sluggish digestive system.

It doesn’t have to be complicated, hydration with electrolytes can be as simple as adding salt to your water or choosing an option with natural ingredients.
