IONTMAX
FuelGel Caffeine Hydrogel 40 g

IONTMAX FuelGel Caffeine Hydrogel is a natural energy gel based on hydrogel technology intended for endurance athletes. Each 40 g serving contains 25 g of carbohydrates from a glucose and fructose blend, and 100 mg of caffeine. The gel is designed for rapid energy replenishment and focus support during running, cycling, triathlon races, or other prolonged physical activities. It contains no maltodextrin, artificial colours, or preservatives.

The gel is designed to be consumed directly during sports performance or prolonged physical activity. Adjust the number of gels and timing based on the duration and intensity of your effort, your planned carbohydrate intake, and your total daily caffeine limit. In a marathon or long cycling ride, it is typically taken at regular intervals according to your own nutrition strategy.

No, the gel does not require water. Hydrogel technology based on sodium alginate and calcium creates a pleasant consistency that can be comfortably consumed even at high intensity—for example, while running or in the saddle. However, it is recommended to drink fluids during physical activity to maintain optimal hydration.

One 40 g gel contains 100 mg of caffeine, equivalent to roughly one cup of filter coffee or 1.5 espressos. This is a significant dose that supports focus and delays fatigue during prolonged effort. When planning your nutrition, consider your total daily caffeine intake from all sources including coffee, tea, and other supplements.

Glucose and fructose are absorbed into the body via different transport mechanisms in the small intestine. Their dual combination allows for more efficient carbohydrate utilisation during long efforts compared to a gel with a single sugar source. One gel contains 25 g of carbohydrates in total (100 kcal). This strategy is widely recommended in sports nutrition for endurance disciplines.

Hydrogel technology uses a natural seaweed biopolymer (sodium alginate) combined with calcium and gluconic acid, which together create a characteristic gel structure. The resulting consistency is significantly more pleasant to swallow than traditional, denser gels; it does not require water and causes less digestive discomfort during high-intensity exercise. For sensitive stomachs, this is a significant advantage over classic formats.

Maltodextrin is a common ingredient in many energy gels; however, it has a high glycaemic index and some athletes find it difficult to tolerate during intense exercise. IONTMAX FuelGel Caffeine Hydrogel replaces maltodextrin with a glucose and fructose blend, which aligns with the philosophy of a clean and natural product. The gel contains no artificial colours, preservatives, or artificial flavours.

No, IONTMAX FuelGel Caffeine Hydrogel contains no declared allergens. The gel formula consists of glucose, fructose, purified water, calcium carbonate, gluconic acid, sodium alginate, and caffeine. The product is free from gluten, lactose, soy, eggs, and nuts. If you have a specific allergy or intolerance, we recommend checking the full ingredients list on the packaging before use.

Based on the ingredients—glucose, fructose, water, calcium carbonate, gluconic acid, sodium alginate, and caffeine—the gel contains no animal-derived components. The sodium alginate is derived from seaweed. The product therefore complies with vegan and vegetarian nutritional criteria, although the manufacturer does not explicitly state a vegan certification on the product.

Combining it with other caffeine sources (pre-workout supplements, caffeine tablets, coffee, energy drinks) increases your total daily caffeine intake. The recommended safe daily dose for healthy adults is up to 400 mg. Since one gel contains 100 mg of caffeine, keep track of your total intake when combining with other sources to avoid adverse effects such as nervousness, heart palpitations, or sleep disturbances.

The gel is primarily designed for runners, cyclists, triathletes, and endurance athletes who value natural ingredients without unnecessary additives. It is suitable for marathons, half-marathons, long rides, triathlons, and Ironmans. For beginner athletes, we recommend considering the intensity of 100 mg of caffeine per serving in relation to your individual caffeine tolerance and the duration of your training.
