How long can I use Energy gels during the exercise?

The evolution of Neapharma energy gels is such that they are nearly as digestible as solid food. Therefore, there is almost no difference in digestibility between gels and solid food. However, solid food is less aggressive in terms of insulin response and has a less significant impact on blood sugar levels, making solid food a more stable and long-lasting source of energy. Energy gels are quicker to be absorbed but also have a faster onset and decline.

Moisture in gels for Speed of Absorption
An additional benefit of moisture in energy gels is the quicker and more complete absorption of carbohydrates. Thick, sticky gels can cause up to 50% loss in absorption. Therefore, moisture in gels is advantageous to increase the efficiency of carbohydrate absorption.”

isotonic gels
Isotonic gels are an outdated concept where you receive fewer carbohydrates and overly focus on fluid intake. A good energy gel contains sufficient moisture (without being isotonic) for the aforementioned reason and, in reality, has nearly the same fluid absorption as an isotonic gel but with a lot more energy.
