The product contains natural flavorings, sodium, potassium, magnesium and calcium. Does not contain allergens, lactose, gluten, wheat or nuts. Suitable for vegetarians and vegans.

Directions for use

Beta Fuel can be used in 3 different ways:

  • During an effort lasting at least 2.5 hours, 60-90 g of carbohydrates per hour from 1 hour.
  • For light exertion, 250 ml of Beta Fuel per hour. At the same time, consume other products belonging to the GO Energy category. In one hour, the body should receive 60-90 grams of carbohydrates.
  • If it is a heavy workout, you could drink 125 ml of Beta Fuel every 15 minutes.

SiS sports drink bottles with markers to mark the correct powder level are great for easy mixing.


Why is the drink powder called Beta Fuel?

Beta Fuel is available for everyone to use, but at the same time, a thorough development process continues. Beta Fuel has been tested by top athletes and teams since 2017. The product itself and the entire product series are being updated.

Why use Beta Fuel?

The ratio of 2:1 maltodextrin and fructose is nothing new in the world of sports nutrition. At the same time, all the drink powders or ready-made drinks on the market have been hypertonic so far. This means that the drink mixture is too “dull” for the digestive tract to cope with its digestion.
