The new and improved Beta Fuel Gel contains 40 grams of carbohydrates in the 1:0.8 ratio between maltodextrin and fructose. This allows you to intake up to 90 grams of carbohydrates per hour.

The optimal 1:0.8 ratio, unlike most energy gels on the market that use a 2:1 ratio, increases carbohydrate availability from 62% to 74%.

The product is ideal for long endurance exercise that lasts at least 3 hours. For shorter exercise, your body will not be able to fully absorb the product. 

Beta Fuel Gel does not cause digestive issues and provides your body with 40 grams of carbohydrates per gel. Its main ingredients are:

✔️ 30% maltodextrin from corn
✔️ 23% fructose

✔️ E
lectrolytes in the form of salt

Due to the 1:0.8 carbohydrate ratio, SiS Beta Fuel Gel allows you to intake up to 90 grams of carbohydrates per hour, depending on the training level of your gut. The gel is simple to dose and does not cause digestive issues.


Maltodextrin is a chain of glucose molecules. Regardless of its complex composition, it has an extremely high glycemic index. Fast availability is crucial, as your body needs to use an external source of energy quickly instead of depleting its own glycogen stores.

Maltodextrin is less sweet than glucose, oxidizes quickly during exercise, and its main benefit is that even if you consume a large quantity of gels, it does not cause digestive issues.

The maltodextrin in the product is derived from corn.

Two types of carbohydrates

Beta Fuel Gel contains two types of carbohydrates: glucose (maltodextrin) and fructose.

Your body can absorb 60 grams of glucose and 30 grams of fructose per hour. Since glucose and fructose use different carbohydrate transporters in your body, a combination of these two sugars allows you to intake up to 90 grams of carbohydrates per hour without bloating or stomach issues.

Beta Fuel Gel is an excellent source of energy that does not cause digestive issues.

  • Quick and efficient source of energy
  • Does not cause digestive issues
  • Two types of carbohydrates
  • With electrolytes (salt)
  • Intake up to 90 grams of carbs per hour
  • Best for long exercise

Consume 1 to 2 energy gels per hour of exercise.

If you also use an isotonic sports drink, adapt energy gel consumption so that you don't exceed an intake of 90 grams of carbohydrates per hour.

The product works best for exercise longer than 3 hours.
