During a long training session or competition, you don't just lose fluid through sweating. Your carbohydrate reserves also decrease. This lowers your energy level and can lead to a decline in performance. The right sports drink helps you maintain both your fluid and energy balance.
But when do you choose a hypotonic, isotonic or hypertonic sports drink? In this blog, we'll explain it simply.
When do you choose a hypotonic, isotonic or hypertonic sports drink?
The difference between these sports drinks lies in the amount of carbohydrates and electrolytes. The more dissolved substances a drink contains, the slower it is usually absorbed.
1) Hypotonic sports drink: when rapid hydration is important
A hypotonic sports drink contains few carbohydrates and is absorbed quickly. This makes it particularly suitable when you primarily want to replenish fluids, for example during shorter efforts, in hot weather or when you sweat a lot.
2) Isotonic sports drink: the best choice during prolonged exertion
An isotonic sports drink contains a balanced amount of carbohydrates and electrolytes. As a result, it replenishes both fluid and energy. For most athletes, this is the ideal choice during training and competitions lasting longer than one hour, such as cycling, running, triathlon, Hyrox and other endurance sports.
3) Hypertonic sports drink: when extra energy is needed
A hypertonic sports drink contains many carbohydrates and provides extra energy. Because this drink is absorbed more slowly, it is less suitable during intensive exertion. Therefore, a hypertonic sports drink is mainly used after a heavy training session or during very long exertions where extra carbohydrates are important.

Why do many athletes choose an isotonic sports drink?
Scientific research shows that isotonic sports drinks offer a good balance between fluid absorption and carbohydrate delivery during prolonged exertion. As a result, they are generally well tolerated and are a suitable choice for many athletes during training and competitions.
Why does Sanas choose an isotonic formula?
Because most athletes need both fluid and energy during prolonged exertion, Sanas deliberately developed an isotonic sports drink. The formula supports an efficient supply of carbohydrates and electrolytes, without unnecessary strain on the stomach.
The Sanas Isotonic offers, among other things:
-
30 grams of carbohydrates per prepared 500 ml bottle for a
constant energy supply - A 2:1 glucose-fructose ratio for efficient carbohydrate absorption
- 250 mg sodium to replenish lost electrolytes during sweating
- A pH-neutral formula without added food acids
- Five flavors without colorants, so there is a suitable choice for every athlete
- Tested for banned substances
This way you get the right combination of fluid, carbohydrates and electrolytes during prolonged exertion.
Note: the ideal amount of fluid and carbohydrates varies per athlete and depends on the duration, intensity and weather conditions of the exertion.
Choose the sports drink that suits your goal
There is no single sports drink that is the best choice in every situation. Do you mainly want to hydrate quickly? Then choose a hypotonic sports drink. Do you need both fluid and energy during a long training session or competition? Then an isotonic sports drink is the best choice for most athletes.

FAQ
Is an isotonic sports drink better than water?
For efforts shorter than one hour, water is usually sufficient. During longer or intensive efforts, an isotonic sports drink helps replenish both fluid and carbohydrates.
Why does a sports drink contain sodium?
Sodium is an electrolyte that you lose through sweat. It helps support fluid balance during prolonged exertion.
