How to use ENDURE ISOFUEL isotonic drink properly.

A practical guide for maximum endurance.

ENDURE ISOFUEL is an isotonic drink that provides you with constant energy, rapid hydration and effective regeneration during long training sessions and competitions. In this article, you will learn how to best use it in practice — from preparation and professional recommendations to answers to the most frequently asked questions.

 

Why is an isotonic drink key for endurance?

During intense exercise, the body loses water, electrolytes and carbohydrates (OH). Isotonic drink:

  • quickly replaces lost fluid,
  • restores key electrolytes (sodium, potassium, calcium and magnesium),
  • provides easily accessible carbohydrates for continuous energy.

Proper use means fewer muscle cramps, better performance, and faster recovery.

You can see the key role of electrolytes and carbohydrates in this article.

 

How to prepare ENDURE ISOFUEL isotonic drink?

Proper preparation of an isotonic drink allows you to achieve optimal carbohydrate and sodium (salt) intake, which is supported by current sports guidelines:

  • Carbohydrates: for activities longer than 60 minutes, it is recommended to consume between 30–60 g of carbohydrates per hour, and for longer efforts, 60–90 g and more carbohydrates per hour (to achieve such values, we recommend slowly acclimating the digestive system).

  • Sodium: It is recommended to consume 300–700 mg of sodium per hour to prevent sodium deficiency and the possibility of muscle cramps.

Scientific sources are listed at the end of the article.

 

What this means for ENDURE ISOFUEL:

1 serving (2 scoops included) contains 25 g of carbohydrates and 350 mg of sodium (and other electrolytes).

  • Shorter training (30–60 min): mix 2 scoops in at least 400 ml of water to cover basic needs.

  • Longer/more intense efforts (1 hour and more): Mix 4 scoops in 700–800 ml of water . This will provide 50 g of carbohydrates and 700 mg of sodium, which is the upper limit of the sodium recommendation. You can also provide an additional source of carbohydrates by using additional energy gels or bars.

 


 

When to drink an isotonic drink?

Before training/match:
This will ensure you are pre-hydrated and energized. We recommend drinking about 30 minutes before your workout to allow the liquid to settle properly.

During training/match:
Drink small sips – the goal is to consume 400–800 ml of prepared drink per hour, but this depends on several factors (heat and intensity, which dictate thirst, and the calculated desired carbohydrate and sodium intake).

After training/match:
Consuming within the first 30 minutes after exercise helps with rehydration and rapid replenishment of carbohydrate (glycogen) stores. After exercise, it is important to consume a quality and specific meal, rich primarily in carbohydrates and protein.

FREQUENTLY ASKED QUESTIONS and ANSWERS

Can I combine an isotonic drink with gels or bars?

Of course. We recommend that you gradually accustom your digestive system to increased carbohydrate intake.

What if I have a sensitive stomach?

When creating the product, we took care to use high-quality ingredients that minimize the possibility of digestive problems. At the same time, we wanted to create a product without unnecessary substances, such as sweeteners and artificial flavors. Start with the recommended dose — 1 serving (2 included scoops) in 400 ml of water, which you can then gradually increase.

Does an isotonic drink replace a meal?

ENDURE ISOFUEL is designed for convenient and fast energy intake and effective hydration during exercise. Always consume a quality recovery meal rich in carbohydrates and protein after exercise.

Is it suitable for shorter workouts (less than 30 minutes)?

Water is sufficient for short, low-intensity workouts. Use an isotonic drink for longer or more intense workouts.

Can I drink it every day?

It is recommended to use it only during activities that can be daily (or even several times a day). Do not forget about sufficient intake of your usual diet.

Can I mix it with electrolyte tablets?

ENDURE ISOFUEL already contains the recommended amount of electrolytes.

Is it suitable for the keto diet?

Unfortunately not, as it contains carbohydrates.
carbohydrates that are not part of the keto diet.

Can adolescents use it?

The isotonic drink is safe for adolescents (10-18 years). The instructions for use are the same as for adults (see above).

How long can a prepared drink last?

It is best eaten fresh within a few hours. If you make it in advance, you can store it in the refrigerator and use it within one hour.
of the day.

ENDURE ISOFUEL is not just a drink — it is a smartly designed part of your endurance training. Prepare it according to proven guidelines, listen to your body, and enjoy every mile without worrying about energy or dehydration!
