Science in Sport Beta Fuel Dual Source Energy Chews, Energy Bars, Lemon Flavour, 45 g of Carbs, 60g Bar (6 Pack)

Product Information

SiS Beta Fuel works by providing these two different forms of carbohydrate which can be simultaneously absorbed. This was successfully tested by world leading associations and teams before becoming the naturally flavoured, informed sport certified product you know today. The new range of Beta Fuel products has an optimised ratio of maltodextrin to fructose. Our previous version used a ratio of 2:1, whilst the new range is 1:0.8. 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. SiS says the new Beta Fuel range is already a favourite of Ineos Grenadiers and that the team has been instrumental in testing and developing the new formula since 2020, with it fuelling Tao Geoghegan Hart to his first Grand Tour victory in the Giro that year.

So, which should you try? Yet again, it boils down to personal preference, but here’s a rough guide:Designed for endurance athletes who strive for peak performance, Beta Fuel Energy Chews are the ultimate fueling solution to help you achieve your goals. 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. The SiS Beta Fuel Gel with Nootropics is available in Apple and Lemon and Lime flavours. For optimal results we recommend consuming the Nootropic Gel during the latter phases of your exercise with a maximum of one serving per day. For more intense and longer sessions of 2 – 2.5 hours or more, SiS Beta Fuel is the next generation of endurance fuelling.

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.

The new SiS Beta Fuel range at 1:0.8 ratio of maltodextrin and fructose is available in a variety of formats, a powder, a unique chew bar and two different types of gels.

So, in 2018, SiS Beta Fuel was developed to enable us to increase carbohydrate oxidation to more than 60 grams per hour and to achieve that, we combined another form of carbohydrate, which has a different transporter, fructose. Because fructose has a different transporter than glucose, a dual source formulation allows for greater carbohydrate delivery to our muscles during exercise, therefore increasing how much carbohydrate we can use. The whole Beta Fuel range is informed sport tested!

Knowing the Science behind the product, I was excited to try it! I'll start with the nutrition issues that I was having. Put simply, I was struggling to get nutrition onboard in enough volume to sustain the rate that I burn it during a race. Take, for example, one early-season E12 race. The 125km race lasted 3 hours and in that time I burned 2,243 calories. My usual nutrition strategy of two 500ml bottles (189kCal each) of SIS Go Energy and around five High5 Energy Gels (91kCal each) left a deficit not just in calories but also in carbohydrate. This intake gave me 209g of carbs. Many cyclists will put endless hours of training in to increase their functional threshold power (FTP – the average number of watts a rider can sustain for an hour) and spend vast amounts of money to upgrade their bikes with the latest gear and gadgets! But few give their nutrition the rightful attention it deserves for them to perform at their best. Our Beta Fuel Dual Source Energy Chews deliver scientifically superior fuel in unique and satisfying chews. Part of an entire world-leading fuelling solution range that includes drinks and gels, they are super easy to consume and deliver 46 grams of carbohydrate to improve and maintain optimum performance. Energy Drink Powder – 80g carbohydrate with neutral pH and isotonic formulation to minimise GI distress

In summary, the SiS Beta Fuel range works by providing these two different forms of carbohydrate in an isotonic 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.For training and competition of 2 – 2.5 hours or more, SiS Beta Fuel is the next generation of endurance fuelling. First launched in 2018, the original Science in Sport Beta Fuel is an isotonic product using both maltodextrin and fructose at a ratio of 2:1 to optimise carbohydrate delivery and utilisation during exercise whilst minimising gastrointestinal issues. Long been favoured by elite athletes, our famous Science in Sport Beta Fuel Energy Drink has now been optimised, making it a scientifically superior fuel. A brand new 1:0.8 ratio of 80g carbohydrate enhances your power output, increases your body's carbohydrate usage efficiency, and limits gastrointestinal discomfort.
