ESN Electrolytes is an electrolyte-carbohydrate powder for intense and prolonged sporting efforts. It combines five electrolytes with dextrin and dextrose in a slightly hypotonic formula.

ESN Electrolytes combines sodium, potassium, magnesium, calcium and chloride. Magnesium contributes to electrolyte balance, while magnesium, potassium and calcium contribute to normal muscle function.¹

The carbohydrates are a deliberate part of the performance formula. Carbohydrate-electrolyte solutions enhance the absorption of water during physical exercise and contribute to the maintenance of endurance performance during prolonged endurance exercise.² Dextrin and dextrose are used as the carbohydrate sources.

Electrolytes is designed for performance, Daily Drip for an active everyday routine. Electrolytes combines electrolytes with carbohydrates for long and intense efforts.

Daily Drip delivers electrolytes without sugar and is geared towards everyday hydration. Available with added extras, depending on the flavour.

Depending on your needs, you can drink ESN Electrolytes before, during and/or after training – whether that's endurance sports like running and cycling, or strength training at the gym. It's especially worth considering for long, intense or sweat-heavy sessions, as well as on particularly hot days.

Hypotonic means a drink contains fewer dissolved particles than blood plasma. As a result, a hypotonic fluid can be absorbed by the body more quickly than an isotonic or hypertonic solution. When prepared as recommended, ESN Electrolytes is formulated to be slightly hypotonic. The carbohydrate-electrolyte solution it contains supports the absorption of water during physical exercise¹ and contributes to the maintenance of endurance performance during prolonged endurance exercise.²

1. What is ESN Electrolytes?

ESN Electrolytes is an electrolyte-carbohydrate powder for intense and prolonged sporting efforts. The formula combines five electrolytes (sodium, potassium, magnesium, calcium and chloride) with the carbohydrate sources dextrin and dextrose.

Mixed with water, it creates a slightly hypotonic drink that combines electrolyte and carbohydrate intake in one. Carbohydrate-electrolyte solutions enhance the absorption of water during physical exercise and contribute to the maintenance of endurance performance during prolonged endurance exercise.¹

Electrolytes is therefore designed specifically for situations that go beyond everyday hydration — for fuelling during sporting exertion.

2. What problem does ESN Electrolytes solve?

During long and intense sessions, the body loses fluid and electrolytes through sweat. At the same time, carbohydrates become relevant as an energy source during exertion. Electrolytes therefore brings both components together in one balanced performance formula.

Hydration meets performance

The combination of electrolytes and carbohydrates is a deliberate choice. Carbohydrate-electrolyte solutions enhance the absorption of water during physical exercise and contribute to the maintenance of endurance performance during prolonged endurance exercise.¹

Magnesium also contributes to electrolyte balance, while magnesium, potassium and calcium contribute to normal muscle function.²

Carbohydrates are part of the concept here

While many electrolyte products deliberately leave out sugar, Electrolytes specifically contains carbohydrates from dextrin and dextrose. When prepared as recommended, the formula delivers around 37 g of carbohydrates per litre.

That's an important part of the positioning: Electrolytes isn't meant as everyday lifestyle hydration but as a performance product for longer, intense efforts.

The result is a 5x electrolyte matrix designed specifically for sporting exertion.

3. What is ESN Electrolytes used for?

Depending on individual needs, Electrolytes can be used before, during or after sport. It's especially relevant for longer, intense or sweat-heavy efforts.

Typical use cases include:

  • longer running and cycling sessions
  • hybrid and endurance training
  • intense or long workouts
  • competitions
  • sport in high temperatures

How much fluid you need depends, among other things, on the duration and intensity of the effort, ambient temperature and your individual sweat rate.

4. Who is ESN Electrolytes suitable for?

Electrolytes is aimed primarily at athletes and sporty people who, during longer or intense sessions, want to take in not just fluid and electrolytes but carbohydrates at the same time.

The product is therefore particularly well suited to endurance and hybrid sports, as well as long or heavily sweat-inducing training sessions. If you mainly want to take in electrolytes in everyday life while avoiding sugar, Daily Drip is the better hydration solution for an active everyday routine.

This creates a clear distinction: Daily Drip for everyday Lifestyle Hydration in an active daily routine, Electrolytes for Performance Hydration.

5. What should you look for when choosing an electrolyte product?

Not every electrolyte product serves the same purpose. What matters first is when and for what it will be used.

Sodium content, the electrolytes it contains, carbohydrates and osmolality are all particularly relevant when choosing a product. Training duration, intensity, temperature and individual sweat rate also influence personal needs.

A key distinction is whether or not the product contains carbohydrates. For everyday hydration, a sugar-free electrolyte solution can make sense. For longer sporting efforts, on the other hand, carbohydrate-electrolyte solutions combine hydration with an additional carbohydrate intake.

What does hypotonic mean?

"Hypotonic" describes the ratio of dissolved particles in the drink to those in blood plasma. A hypotonic drink contains fewer dissolved particles — such as electrolytes and carbohydrates — than blood plasma.

When prepared as recommended, Electrolytes is formulated to be slightly hypotonic. The combination of around 1,100 mg of sodium and 37 g of carbohydrates per litre was put together specifically for fluid and carbohydrate intake during sporting exertion.

6. What sets ESN Electrolytes apart from similar products?

The key difference lies in its performance approach. Electrolytes doesn't simply combine several electrolytes — it pairs a 5x electrolyte matrix with carbohydrates from dextrin and dextrose in a slightly hypotonic formulation.

This means the product addresses exactly the situations where hydration and energy intake both matter. Carbohydrate-electrolyte solutions enhance the absorption of water during physical exercise and contribute to the maintenance of endurance performance during prolonged endurance exercise.¹

With around 1,100 mg of sodium and 37 g of carbohydrates per litre, five electrolytes and a fructose-free carbohydrate combination, Electrolytes is purpose-built for long, intense efforts.

Do not exceed the stated daily intake. Food supplements are not a substitute for a balanced and varied diet and healthy lifestyle. Store out of reach of youngchildren.

¹ Carbohydrate-electrolyte solutions contribute to the maintenance of endurance performance during prolonged endurance exercise.

² Magnesium contributes to electrolyte balance.

³ Magnesium contributes to normal muscle function. Magnesium contributes to the normal function of the nervous system.

⁴ Electrolytes has been tested for heavy metals, microbiology, nutritional values and osmolarity to substantiate better hydration.
