General – Why hydration is crucial in sport

Whether you are an endurance, strength or hybrid athlete: anyone who pushes themselves to their limits in training or competition loses not only fluid but also valuable electrolytes. Even a fluid loss of 2% of body weight, about 1–2 litres of sweat, can have a negative effect on endurance, concentration and performance. And this happens faster than you might think – especially in hot weather or during long sessions.

Effective rehydration is therefore a fundamental part of any training routine. Water alone is often not enough: it lacks electrolytes and carbohydrates, which support fluid transport and keep the body performing at its best. This is exactly where Hydroload comes in – as a modern carbohydrate-electrolyte solution for ambitious athletes.

Why ESN Hydroload

Hydroload is the first carbohydrate-electrolyte product from ESN – developed for anyone who pushes themselves to the limit during training. The formula delivers:

• 17-18 g of carbohydrates per serving (from dextrose and dextrin)

• a 5-fold electrolyte matrix (sodium, chloride, potassium, calcium, magnesium)

The combination of rapidly available carbohydrates and high-dose electrolytes is exactly what your body needs during intense exercise – no fructose, no added sugar, 100% vegan.

And best of all, Hydroload is available in two varieties – with a neutral flavour for combining with shakes or pre-workouts, and in refreshing flavours for classic mixing with water. This means the product can be adapted to your daily training routine and preferences.

Advantages of Hydroload in detail

1. Carbohydrates + electrolytes – a well-thought-out combination

Hydroload is based on the proven formula: carbohydrates + electrolytes. According to leading sports science organisations (ISSN and EFSA), this combination has the following advantages:

• Improved water absorption during physical exertion

• Maintaining endurance during longer sessions

Dextrin and dextrose provide quickly available carbohydrates that serve as a source of energy for the body during prolonged exertion and support fluid transport into the tissues.

2. Electrolytes for muscle function and fluid balance

The electrolytes contained – sodium, chloride, potassium, calcium and magnesium – fulfil important functions:

• Magnesium contributes to normal muscle function and reduces fatigue

• Potassium supports the normal functioning of the nervous system and muscles

• Calcium also contributes to normal muscle function

• Sodium & chloride together regulate fluid balance

Sodium in particular is excreted in large quantities during heavy sweating – Hydroload therefore provides a specifically higher dosage than conventional isotonic drinks.

3. Hypotonic formula for rapid rehydration

The Hydroload formula is hypotonic, which means it contains fewer dissolved particles than blood plasma – this allows the drink to be absorbed by the body particularly quickly.

A clear advantage for anyone who wants to replenish efficiently during exercise.

Conclusion

Hydroload is the well-thought-out solution for modern athletes who want to not only drink during intense workouts, but also rehydrate in a targeted manner. The combination of 17 g of carbohydrates and five functional electrolytes per serving ensures rapid absorption, clear effects and versatile application.

Whether as a classic sports drink for long runs, at the gym or during CrossFit – or as a neutral-tasting base for your shake: Hydroload delivers what your body needs when exposed to heat and volume. Functional, vegan, fructose-free – and ready to fuel your flow.

FAQ

When should I take Hydroload?

Ideally during or immediately after intense sessions – especially during longer endurance workouts, hybrid sessions or competitions where you sweat heavily. It is particularly recommended if the exertion lasts for more than an hour.

Can I combine Hydroload with other ESN products?

Yes, Hydroload can be combined well with our other pre-workouts, intra-workouts and EAAs – especially in the unflavoured version. However, Hydroload is also designed so that you can consume it during training without taking any other products.

Is Hydroload isotonic?

No – Hydroload is hypotonic, which means that it is absorbed particularly quickly by the body – an advantage in cases of severe fluid loss.

Is Hydroload vegan and fructose-free?

Yes – the product is 100% vegan and contains no fructose. Dextrin and dextrose serve as carbohydrate sources.
