No, you don’t need to ‘earn’ your electrolytes

Cheers to debunking the electrolyte myths on your ‘FYP’.

Electrolyte tablets and powders are expected to account for 36.2% of the global hydration supplement market in 2026. Once the preserve of endurance athletes, they have officially moved beyond the sports bottle and into everyday hydration. But as electrolytes become increasingly difficult to escape, the question is no longer about how they are having their moment, but if we actually need them.

There is something slightly funny about electrolytes' trajectory. For years, it belonged almost exclusively to people who could tell you their average kilometre pace without looking at their Strava. Then it found a second life as the unofficial hangover accessory, promoted as a way to recover from the previous night's excesses. Now it has become part of the wider hydration economy. You can’t walk through Tesco without seeing one at the tills.

The expansion makes sense as electrolytes are minerals including sodium, potassium, and magnesium, and they play important roles in fluid balance, muscle function, and nerve signalling. We lose electrolytes when we sweat, which makes them particularly relevant during prolonged or intense exercise, in hot conditions, or when we experience substantial fluid loss. But the fact that something is useful in certain circumstances doesn't make it essential in all of them. Most healthy people can meet their everyday electrolyte requirements through food and ordinary fluids.

The current hydration market increasingly suggests that every glass of water represents an opportunity for optimisation, as though plain water is the basic model and electrolytes are the premium upgrade. It is an appealing idea, particularly in a wellness culture that has become very good at turning ordinary biological functions into projects. Hydration does not, however, need to become another thing to get “right”.

Take an entirely unremarkable Tuesday. You wake up, have breakfast, walk to work, sit at a desk, drink coffee, eat lunch, and perhaps head to a Pilates class after work or for a drink with your mates. Nothing special, and you could meet your daily hydration intake. But by moving around in your busy day, that means significantly greater fluid and electrolyte losses. That's where an electrolyte product becomes less of a wellness accessory and more of a practical bit of sports nutrition. There are daily situations in which replacing what you've actually lost makes physiological sense.

The hangover is slightly more complicated. Electrolytes have become synonymous with the morning-after recovery ritual, and rehydration can help when you've lost fluids, but an electrolyte sachet cannot erase alcohol's effects or compensate for a night without sleep. Unfortunately, time remains the most reliable hangover treatment.

This is perhaps why the electrolyte boom is worth looking at with a little more nuance. The category has escaped the gym, and that is not necessarily a bad thing. Making hydration more convenient, portable, and appealing can be useful, particularly for people who struggle to drink enough during travel, exercise or hot weather.

At Balance, that distinction is the interesting bit. An electrolyte isn't something you need to earn by running ten kilometres, nor is it something you need to add automatically to every glass of water. It is simply another tool, useful in the circumstances where your body has actually given you a reason to reach for it. And in an increasingly crowded hydration market, knowing when you don't need something might be just as valuable as knowing when you do.
