Energy intake without eating, used by the pros
Do you find it difficult to eat in the heat of the moment? Science in Sport Beta Fuel has been developed to provide the maximum amount of carbohydrates in an ultra-energising drink that is sufficient on its own to perform throughout a competition while limiting gastrointestinal distress.

SiS powder can be compared to the famous Gallic magic potion... A clever blend with a concentration of 80 grams of carbohydrates (with a 2:1 maltodextrin/fructose ratio), 20mmol/L of sodium and 600ml of liquid per bottle. With Beta Fuel, you can put away your energy bars and gels...The main adversary of sports nutrition is the factor that limits the rate of exogenous carbohydrate utilisation during exercise: the transport of nutrients across the intestinal wall. Once the sodium-dependent transporter, used to transport maltodextrin, is saturated at 60 g.h, additional carbohydrates can be absorbed by another transporter, GLUT5, used to transport fructose. This assimilation chain is precisely controlled by Sis Beta Fuel.
The fuel requirements for long endurance events (over 2.5 hours) are 60 to 90g of carbohydrates per hour. The ability to provide such high levels of carbohydrates with minimal risk of gastrointestinal problems is crucial for performance. Sis Beta Fuel can be used to meet these fuel demands in an isotonic solution.Suitable for: vegans, vegetarians, coeliacs, lactose-free, gluten-free, wheat-free, nut-free.Nutritional information per 100ml:
