Sports drink or electrolyte drink – what is the difference between them?
Share
Short answer: A sports drink usually contains a significant amount of carbohydrates and serves as a source of both energy and fluid. An electrolyte drink primarily contains water and electrolytes, and may contain little to no carbohydrates. Which one you should choose depends on how you get your energy during your performance.
A sports drink and an electrolyte drink are not the same thing
| Sports drink | Electrolyte drink | |
|---|---|---|
| Carbohydrates | Usually significant | Little or none |
| Electrolytes | Usually yes | Yes |
| Main purpose | Energy + hydration | Hydration + electrolytes |
| Best use | Long workouts and competitions where carbohydrates are needed | When energy comes from gels/food or a high amount of carbohydrates is not needed |
When should you choose a sports drink?
A sports drink is practical when you want to get some or even a large portion of your carbohydrates during a workout from the drink. It is particularly suitable for cycling, running, triathlons, and other endurance sports.
Carbohydrates help maintain available energy during a long performance. In established sports nutrition guidelines, the amount of carbohydrates increases as the performance duration increases. For performances lasting over 2.5–3 hours, the target has long been around 90 g/h using products consisting of multiple transportable carbohydrates. A 2026 review estimates that for well-trained athletes, the upper limit may in some situations rise towards 120 g/h, but this amount should not be interpreted as a new general recommendation.
High carbohydrate intakes should be practiced gradually, also for the sake of gastrointestinal tolerance.
When is an electrolyte drink better?
An electrolyte drink often makes sense when carbohydrates come from elsewhere. If you use gels, energy chews, or bars, for example, a low-carbohydrate drink makes it easier to calculate your fueling and prevents unintentional doubling of carbohydrates.
An electrolyte drink can also be useful in hot weather, when you need a lot of fluid but do not want to increase your carbohydrate intake proportionally.
What about a short workout?
For a workout of about an hour or less, plain water is often sufficient, provided the workout is not exceptionally hot, intense, or cause heavy sweating. Not every workout needs a separate sports or electrolyte drink.
The carbohydrate target determines the role of the drink
Fueling should be considered as a whole hour's total, not through an individual product.
Example: if your goal is 90 g of carbohydrates per hour and you get 45 g/h from gels, the task for the drink and other nutrition remains about 45 g/h. If you already get 90 g/h from the drink, the gels consumed in the same hour would be in addition to that.
This is one reason why some athletes use a very carbohydrate-rich sports drink as the foundation for almost their entire fueling, while others combine an electrolyte drink with gels.
What about sodium?
Both sports drinks and electrolyte drinks can contain sodium, but the amounts vary greatly. "Electrolyte" in a product's name does not automatically mean a high sodium content.
If you sweat a lot or the workout lasts for several hours, check the label for the amount of sodium or salt per serving and per liter. Read also Electrolytes and sodium in endurance sports.
Can you combine a sports drink and an electrolyte drink?
Yes, but usually they don't have to be in the same bottle. For example, on a long bike ride, one bottle can contain a carbohydrate-rich sports drink and the other a lighter electrolyte drink or water. This gives more flexibility in regulating energy and fluid.
Sports drink or gels + electrolyte drink?
Both strategies can work. The choice is practical:
- Sports drink-oriented: little to chew or open, energy is carried in the bottle.
- Gels + electrolyte drink: energy and hydration can be adjusted independently of each other.
- Combination: often the easiest way to get variety in a long race.
Stomach tolerance and personal preferences count for a lot. It is worth practicing race fueling during long workouts.
Choose this way
- I need energy and fluid at the same time: sports drink.
- I eat gels/bars and mainly want fluid from my drink: electrolyte drink.
- Short workout: water may be enough.
- Long race: calculate the total carbohydrates from all sources and plan fluid/sodium separately.
Frequently asked questions
Is an electrolyte drink a sports drink?
Not necessarily. A sports drink usually contains a significant amount of carbohydrates, whereas an electrolyte drink can be almost calorie-free.
Can you replace gels with an electrolyte drink?
Only if the product has enough carbohydrates. A low-carbohydrate electrolyte drink is not a significant source of energy.
Is a sports drink needed for a workout under an hour?
Most often, no. Water may be enough, but heat, the intensity of the workout, and individual sweating affect this.
Is 120 g of carbohydrates per hour the new recommendation for everyone?
No. The 2026 research review considers higher amounts, up to about 120 g/h, as possible for some well-trained athletes, but the research evidence is still evolving. For many, 60–90 g/h is already a large amount and requires training.
