Even after 3 hours of sustained effort 50% of energy used was from the SiS Beta Fuel, rather than the body’s own fuel stores, with no cross-over from carbohydrate to fat usage taking place Jeukendrup A.E. Carbohydrate feeding during exercise. Eur. J. Sport Sci. 2008; 8:77–86. doi: 10.1080/17461390801918971. A 1:0.8 ratio of glucose to fructose reduces self-reported symptoms of stomach fullness when compared with a ratio of 2:1 The new Beta Fuel Powder solution contains 80 grams of carbohydrate at this 1:0.8 ratio, in a neutral pH formula that maintains the signature isotonic format to minimise gastrointestinal issues.
O’Brien, W. J., Stannard, S. R., Clarke, J. A., & Rowlands, D. S. (2013). Fructose–maltodextrin ratio governs exogenous and other CHO oxidation and performance. Medicine & Science in Sports & Exercise, 45(9), 1814-1824. Haven’t used Beta Fuel yet. I’m a bit puzzled though what all the rave is about it. Well, truth be told there isn’t really that much rave. Because it’s known for quite a bit of time that the digestive system seems to be able to absorb carbs a bit better or more of them per unit of time if you mix Glucose with Fructose around 2:1. While every SIS product up to now simply had Fructose in it they now hyped it with that Chris Froome story of that Giro stage. Well… Team sky could have such “sucesses” for many years already if they had just used one of the not so few (I guess) products which use this “formula” already for quite some time. Take e.g. Powerbar with their C2max. That’s “Beta Fuel” right here and there since… forever? In summary, the Science in Sport Beta Fuel range works by providing these two different forms of carbohydrate in a formula which can be simultaneously absorbed. This is key as the transportation of nutrients across the intestinal wall, which is a rate-limiting factor in carbohydrate oxidation during exercise.
Be mindful of caffeine as it doesn’t suit everyone,” warns Wiener. “Some people find it makes them dehydrate faster or need to use the toilet more, which is not what you want if you’re taking on a big race or event.” Energy Drinks, Gels Or Chews?

These chewable energy bars provide a world-leading and scientifically optimized source of fuel, ensuring you have the energy and stamina to go the distance. When considering trying to consume 80-120g of carbohydrate per hour, individuals may take time to adapt to consuming this amount of carbohydrate and the optimal amount per hour may also vary slightly depending on the individuals body weight. It is important to practice your nutrition during training to find the optimal amount that works for you.
Beta Fuel has worked perfectly for me all year. The drink is tasty enough and presents no stomach issues. Saving it for race day, where the carb concentration is needed, makes the cost acceptable for me. There is no funny consistency and as a result, this has become an essential for me. Verdict For those who like to consume gels whilst running, the SiS Beta Fuel Gel with Nootropics could be a game changer during that last push. Ideal for when you are in the last quarter of your marathon, you know the end is near, it is all going to be worth it, but your physically and mentally exhausted and in need of a boost to help give you that push to the finish.
