Electrolyte drinks vs sports drinks
These get shelved together and used interchangeably, but they are built to solve different problems. The distinction is carbohydrate, and it decides which one is right for you.

Three categories, not two
It is cleaner to think in three groups, because the third is the one people most often reach for at the wrong moment.
1. Electrolyte mixes
Minerals with little or no carbohydrate. The job is replacing what you lose in sweat, or topping up sodium on a low-carb diet. LMNT Zero Sugar Electrolytes, Raw Unflavoured is the clearest example here: 1000 mg of sodium, 0 g of sugar, 0 calories. There is no fuel in it because fuel is not what it is for.
2. Sports drinks
Carbohydrate solutions with sodium added. The job is delivering energy during sustained exercise, with fluid and minerals alongside. Skratch Labs Sport Hydration Drink Mix sits here deliberately: 19 g of sugar and 80 calories per serving, alongside 400 mg of sodium. The sugar is the point, not a compromise.
3. Oral rehydration solutions
A specific formulation with a defined ratio of glucose to sodium, designed to maximise fluid absorption rather than energy delivery. Glucose and sodium are absorbed together in the small intestine through a shared transporter, and moving them together pulls water across with them. That mechanism is what makes oral rehydration therapy effective, and it is why DripDrop ORS contains 7 g of sugar rather than being sugar-free.
The short version
Replacing minerals → electrolyte mix. Fuelling something long → sports drink. Recovering from illness or serious fluid loss → oral rehydration solution. Trouble starts when a product from one category gets used for another category's job.
How to decide, by duration
| Situation | What you need | Why |
|---|---|---|
| Desk, daily hydration | Water, usually | Diet already supplies ample sodium for a sedentary day. |
| Under 60 min exercise | Water | Glycogen covers the effort; losses are small enough to replace at the next meal. |
| 60–90 min, or hot | Electrolyte mix | Sweat losses become worth replacing; fuel generally does not yet. |
| Over 90 min | Sports drink | Carbohydrate starts to matter for performance, and one bottle can do both jobs. |
| Illness, vomiting, diarrhoea | Oral rehydration solution | The glucose-to-sodium ratio is formulated specifically for fluid absorption. |
Where the marketing blurs it
Almost every product in this category is sold with the same visual language — athletes, heat, exertion — regardless of which of the three groups it actually belongs to. A zero-sodium daily mix and a 1,000 mg sweat-replacement stick can look near-identical on a shelf.
The panel resolves it in seconds. Sugar tells you whether it is a fuel product; sodium tells you whether it is a sweat-replacement product. Our comparison table lays both out for all ten, and the sodium guide covers how much you need.
Common questions
Is Gatorade an electrolyte drink?
It is a sports drink — a carbohydrate solution with sodium added. It contains electrolytes, but its primary design purpose is delivering carbohydrate during exercise. Gatorade also makes Gatorlyte, which is positioned differently, with a wider mineral spread and less sugar.
Can I just use an oral rehydration solution for exercise?
You can, and for rehydrating after heavy losses it works well — that is the formulation with the strongest evidence behind it. What it is not designed to do is fuel a long effort, because the carbohydrate concentration is deliberately kept low to optimise fluid absorption rather than energy delivery.
Do I need carbohydrate in my drink for a one-hour workout?
Generally no. Muscle glycogen comfortably covers efforts around an hour, so for most sessions of that length a drink with sugar in it is providing calories you did not need. Carbohydrate during exercise starts to matter as sessions extend well past that.
