The Isotex+ Gel from Scientific Nutrition provides 40 g of carbohydrates, based on maltodextrin and fructose, per 60 g gel. It also contains 300 mg of sodium as well as potassium, offering a combination of essential minerals to maintain electrolyte balance, regulate hydration, and support proper muscle function.

Maltodextrin is a source of fast-releasing energy. It is a polymer of glucose primarily derived from starch and is quickly absorbed by the body. It has a high glycemic index, meaning it is rapidly released into the bloodstream, serving as an immediate energy source for intense and long-duration sports. Fructose is a type of simple sugar found in fruits, honey, and certain vegetables, with slower absorption and prolonged energy release, which is beneficial during extended high-intensity exercise.

• Transporter SGLT1: Glucose or polymer of glucose (maltodextrin)
• Transporter GLUT5: Fructose

The combination of fructose and glucose increases the rate of carbohydrate absorption to 90-120 g/h, depending on the chosen ratio, thanks to the use of different intestinal transporters. When maltodextrin and fructose are combined, more prolonged absorption is achieved.

Electrolytes play a fundamental role in physical performance and overall health of athletes. During intense exercise, the body loses large amounts of electrolytes (primarily sodium but also potassium, calcium, and magnesium) through sweat. These minerals are essential for maintaining electrolyte balance, regulating hydration, and ensuring proper muscle function. The lack of these salts can lead to fatigue, muscle cramps, and reduced athletic performance. It is important to replenish these salts through diet and the use of supplements specifically designed for hydration and restoring electrolyte levels.

Electrolyte needs vary depending on the type of activity, the duration of exercise, the climate, and the individual characteristics of each athlete. It is important to adjust electrolyte replenishment to individual needs.
