Isotex Gel Natural 60gr

The Isotex+ Gel from Scientiffic Nutrition provides 40g of carbohydrates, based on maltodextrin and fructose, per 60g gel. It also contains 300mg of sodium and potassium, a combination of essential minerals for maintaining electrolyte balance, regulating hydration, and supporting proper muscle function.

Maltodextrin is a fast-release energy source. It is a glucose polymer primarily derived from starch. The body absorbs it quickly due to its high glycemic index, meaning it is rapidly released into the bloodstream. This makes it an immediate energy source for intense and long-duration sports, as well as for replenishing muscle and liver glycogen. However, when only glucose or glucose polymers like maltodextrin are consumed, the absorption rate is ~60 g/h, so we cannot absorb more energy through this carbohydrate, no matter how much we increase its intake.

Fructose is a type of simple sugar (monosaccharide) found in fruits, honey, and some vegetables. Its absorption is slower than that of glucose. It provides sustained energy release, which can be beneficial during prolonged high-intensity exercise, especially when combined with other carbohydrates.

The intestine has two main systems for carbohydrate transport:

• SGLT1 Transporter: Glucose or glucose polymers (maltodextrin)

• GLUT5 Transporter: Fructose.

By combining fructose and glucose, we can increase the carbohydrate absorption rate to 90-120 g/h, depending on the chosen ratio. This is possible due to the use of different intestinal transporters. When we combine maltodextrin and fructose, we achieve similar results but with more prolonged absorption.

Electrolytes play a fundamental role in physical performance and the overall health of athletes. During intense exercise, the body loses large amounts of electrolytes (mainly sodium, but also potassium, calcium, and magnesium) through sweat. These minerals are essential for maintaining electrolyte balance, regulating hydration, and ensuring proper muscle function. A deficiency of these salts can lead to fatigue, muscle cramps, and reduced athletic performance. To prevent the above, it is important to replenish salts through diet and, depending on the intensity of your exercise, through the use of supplements specifically designed for hydration and electrolyte level restoration. Electrolyte needs vary depending on the type of activity, duration of exercise, climate, and individual characteristics of each athlete. Therefore, it is important to pay attention to these factors and adjust electrolyte replenishment to your individual needs.
