Frequently Asked Questions
Is hydration important in sports? The role of isotonic drinks
Hydration is key in sports to maintain performance, avoid muscle cramps, and prevent dehydration. During intense exercise, the body loses fluids and minerals through sweat, which can affect endurance and muscle recovery.
Isotonic drinks are essential because they help replenish electrolytes.(sodium, potassium, magnesium and calcium), carbohydrates and water, allowing for better absorption and maintaining the body's water balance.
At FANTÉ you will find the best isotonic drinks for athletes, designed to optimize hydration before, during and after physical exercise.
What is the difference between isotonic, hypotonic, and hypertonic drinks?
Sports drinks are classified into three types according to their solute concentration compared to blood:
- Isotonic drinks:They have a concentration similar to that of blood plasma, which facilitates rapid fluid and electrolyte replenishment, making them ideal for endurance sports such as cycling, running, or triathlon. Fanté's flagship isotonic drink is Iso Drink at 6% concentration. With it, you'll achieve the best hydration on the market, as we pay close attention to the drink's osmolarity and its function in the body. In this case, it's used during exercise at a 6% concentration.
- Hypotonic drinks:They contain a lower concentration of solutes, promoting ultra-fast absorption. They are recommended for short, intense sessions or in very hot climates. You can obtain this beverage by adding more water than recommended to our sports hydration products.
- Hypertonic drinks:They contain a higher amount of carbohydrates, used to replenish energy after exercise, like ourGlycogen Recovery Drink.
What are the benefits of choosing natural isotonic drinks without additives?

Benefits of natural isotonic water:
- They replenish essential electrolytes such as sodium, potassium, and magnesium, improving endurance
- They promote hydration without artificial chemicals, avoiding digestive discomfort.
- They use natural carbohydrates such as corn maltodextrin or honey, providing sustained energy.
- They improve absorption and digestion, without causing glucose spikes.
What is the difference between a conventional carbohydrate drink and a natural carbohydrate drink?
Thepowdered carbohydrate drinksThey are an essential source of energy for long-duration workouts. However, it is important to differentiate between them.conventional formulasand thedrinks with natural carbohydrates and no additivesbecause their impact on performance and health is very different.
Theconventional carbohydrate drinksThey are usually formulated withglucose, palatinose, isomaltulose or refined maltodextrinFurthermore, they containcolorings, artificial sweeteners, preservatives and flavoringsThese combinations provide quick energy, but they can also generateglucose spikes, affect thegut microbiotaand provokeearly fatigueEven so, they are usually a more economical option.
On the other hand, thenatural carbohydrate drinksThey use sources such asmaltodextrin with less than 50,000 ppm and fructoseIt contains no preservatives, artificial sweeteners, or added flavors.absorption is more progressive and stable, which favors asustained energy, aeasier digestionand a better intestinal balance.
