Active Ingredients & Science

The key active ingredient is Karbolyn®, a patented homopolysaccharide derived from potatoes, rice and maize. Karbolyn® is known for its unique molecular structure, which provides a rapid, steady release of carbohydrates in the body. This form of carbohydrate has good bioavailability and is broken down more slowly than ordinary sugars, making it a steady source of energy during physical activity. Thanks to its composition, Karbolyn® is gentle on the stomach and mixes easily with water or other drinks, making it easier to tailor your intake to your needs.

Benefits & Uses

  • Flexible use: Its neutral flavour means you can mix Karbolyn Fuel with any drink or protein powder without affecting the taste.
  • Easy to mix and gentle: The powder dissolves quickly in liquid and is gentle on the stomach, which can be beneficial for people with sensitive stomachs during physical exertion.
  • Suitable for different lifestyles: Whether you are an elite athlete, a fitness enthusiast or active in everyday life, Karbolyn Fuel can provide a steady source of energy that is easy to use.

Use & Dosage

Karbolyn Fuel can be mixed with water or any drink and taken as needed, for example around workouts or as an energy supplement during the day. For best results, the product can be combined with protein powder or other supplements used in connection with exercise. Follow the directions to ensure optimal use and effect.
