Hydration
Electrolyte drinks and mineral salts for when plain water falls short. Find the format that fits you: electrolyte powder for your bottle, isotonic gel and pocket-sized chews for hard efforts, and flavorings that give water some taste and help you drink more through the day.
Pick the one that matches the moment. For everyday drinking, try a water flavoring. If your session runs past the hour or the heat kicks in, grab isotonic drink powder. And if you train without stopping to drink, the gel and chews go in your pocket.

Drinking isn't always hydrating
Electrolytes and mineral salts for every type of session
Electrolytes, or mineral salts, are the minerals you lose in sweat: sodium, potassium, magnesium, calcium and chloride. This category gathers the ways to replace them, with carbohydrates and without, for the one-hour gym workout and for long summer outings alike.

Electrolyte drinks: which format fits you
We carry powder, gel and chews; there are also salt capsules and effervescent tablets, which provide sodium without carbohydrates and are taken with water. Decide by duration, heat and whether you can stop to drink.
Water flavoring
A flavoring gives water taste with barely any calories and helps you drink more, but it provides very little sodium: it won't replace what you sweat out in a long workout. It's the format for everyday drinking and short sessions: find them in water flavorings.
Isotonic powder
Isotonic drink powder adds carbohydrates to the electrolytes: one dose in the water the label states, and one or two bottles an hour when it's hot out. For efforts over an hour.
Isotonic gel
Isotonic gel concentrates the dose in one sachet, taken with a sip of water. Guide: one every 30-45 minutes. It fits running, cycling or padel, when you can't stop to mix a bottle. More options for what to take during training.
Electrolyte chews
Electrolyte chews are chewed instead of drunk. Count their grams of carbohydrate within the 30-60 g per hour reference, together with whatever is in your bottle. They fit when your stomach has had enough of sweet liquid.
Daily combo
The combo brings together creatine, electrolytes, magnesium and collagen in one tub. For anyone who already takes creatine daily and doesn't want more tubs piling up.
Water, electrolytes or isotonic
What separates an electrolyte drink from an isotonic drink is the final concentration, and in practice carbohydrates are what raise it.
Short sessions
Water alone
Water covers sessions under an hour at moderate intensity. It doesn't replace the sodium you sweat out, and the American College of Sports Medicine advises against drinking large volumes of sodium-free water in long efforts.
Every day
Electrolyte drink
An electrolyte drink provides water and minerals — sodium, potassium, magnesium — with barely any calories. In practice it's hypotonic: it replaces fluid and salts, not carbohydrates. Its place is everyday drinking and hot days.
Over an hour
Isotonic drink
An isotonic drink adds carbohydrates to the electrolytes, at a concentration close to that of body fluids. It's the only one of the three that can say it contributes to the maintenance of endurance performance during prolonged endurance exercise, and only if it meets the composition the rules require.
What to check before you buy
Four facts on the label, always for the liter as prepared, not the dose.
Milligrams of sodium per liter
Sodium is the mineral you lose most in sweat, and the figure labels hide best. To use its claims, Regulation (EU) No 432/2012 sets 460-1,150 mg per liter for carbohydrate-electrolyte solutions. If the label only gives salt per dose, divide it by 2.5 and scale it up to a liter.
Which minerals come with it
Sodium always; potassium and magnesium add up. Check the declared amount of each, not just the "mineral salts" on the front label: natural flavorings and colorings don't replace those figures.
Sugars and kilocalories
Zero sugar for every day; carbohydrates for long efforts. EU rules require 80 to 350 kcal per liter from carbohydrates to claim prolonged endurance performance: a sugar-free drink doesn't reach that, and it isn't meant to.
The liters you get from the tub
Divide the grams in the tub by the grams per dose: that's the real number of liters you'll prepare. It's how you compare tubs of different sizes without trusting the front label.
Tip: sip from the start, not once you're already thirsty. In the heat, drink more volume at the label dose; if you dilute it to drink more, add sodium separately. How to spread your drinking across the day is covered in how to hydrate the right way.
Frequently asked questions
What are electrolytes and what do they do?
Electrolytes are electrically charged minerals — sodium, potassium, magnesium, calcium and chloride — dissolved in your body's fluids. Potassium, magnesium and calcium contribute to normal muscle function. You lose them when you sweat, sodium most of all, which is why sports drinks add them back. More in why we need to replenish electrolytes.
What's the difference between an electrolyte drink and an isotonic drink?
Concentration. An isotonic drink has an osmolality close to that of blood, around 275-295 mOsm/kg; a sugar-free electrolyte drink usually sits well below that: it's hypotonic. What brings a sports drink close to isotonic is the dissolved carbohydrate, and only with 80-350 kcal from carbohydrates and 460-1,150 mg of sodium per liter can it use the EU claims. More in isotonic, hypotonic and hypertonic drinks.
Which do I need: sugar-free electrolytes or an isotonic drink?
It depends on whether you need carbohydrates. For everyday use or sessions under an hour, water is enough; a sugar-free flavoring helps you drink more, though it provides very little sodium. For efforts over an hour, isotonic drink powder: it provides sodium plus the carbohydrates the rules require to claim prolonged endurance performance.
Are there electrolyte drinks without sugar?
Yes: sugar-free electrolytes come as powders, effervescent tablets or capsules, providing sodium with barely any calories. Flavorings are something else: they give water taste and help you drink more, but they provide very little sodium. One catch: without 80 kcal of carbohydrates per liter, EU rules don't allow the claim that a drink contributes to the maintenance of endurance performance during prolonged endurance exercise.
Where can I buy electrolytes?
At pharmacies, supermarkets, sports shops and nutrition stores like this one. The channel doesn't change the product: what changes is the label. In supermarkets, drinks with little sodium and plenty of sugar sit next to others that comfortably meet the rules. Compare the milligrams of sodium per liter as prepared, the declared minerals, and the liters you get from the tub.
Is an oral rehydration solution from the pharmacy the same as an electrolyte drink?
No. Oral rehydration solution is a medicine for dehydration caused by diarrhea: it carries about 90 mmol of sodium per liter, over 2 g. A sports drink that uses the EU claims has 20 to 50 mmol per liter and usually more carbohydrates, because it's designed for exercise. They aren't interchangeable.
Do I need electrolytes if I train for under an hour?
Usually not: water is enough for a short session at moderate intensity. Replacing sodium pays off once you pass the hour mark, when it's hot, or if you sweat especially salty. You lose between 0.5 and 2 liters of sweat per hour, with 10 to 70 mmol of sodium per liter.
Is it good to take electrolytes every day?
Not if you eat normally: a varied diet covers the sodium, potassium and magnesium most people need. Daily use makes sense if you sweat heavily on a regular basis, and in that case go sugar-free, so you don't add calories you're not burning. When it pays to replace them, in why we need to replenish electrolytes.
How do I know if I need to replenish electrolytes?
By objective signs: you've sweated for more than an hour, or the scale shows at least 2% less weight than before you trained. Those are the two figures that actually tell you it's time to replace fluid and sodium, more reliable than how you feel in the moment.
