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. Whether your goal is to improve your endurance capacity, get leaner or build strength, we can support you in achieving your goals.Consume during prolonged exercise to meet your fuelling requirements. Fuelling strategy – 2-hour event at 80-120g of carbohydrate per hour Science in Sport Beta Fuel is leading a revolution in endurance fuelling by using both maltodextrin and fructose to optimise carbohydrate delivery and utilisation during exercise whilst minimising gastrointestinal issues. As an endurance athlete exerting your body for periods typically longer than two hours, you need to take in between 80-120g of carbohydrate per hour. Our Science in Sport Beta Fuel Dual Source Energy Gel Chews deliver 46g of fast carbs in a convenient and tasty chew, which have been optimised with a new ratio that enhances power output and increases carbohydrate usage efficiency without gastrointestinal discomfort. The SiS Beta Fuel gel with Nootropics contains 1g of the amino acid L-taurine, 250mg Cognizin® to enhance information processing and also 200mg caffeine with 200mg L-theanine, the amino acid which has been shown to both reduce feelings of ‘jitters’ that you get with caffeine, while increase subjective feelings of alertness.

While burning fat might sound like a good thing, fat stores don’t release as much energy at the same rate, says Wiener. When you’re outta carbs, you’re likely to hit the proverbial wall, and your performance will suffer. The groundbreaking research behind Beta Fuel Energy Chews has yielded impressive results. Studies conducted by O'Brien et al. have shown that the 1:0.8 carbohydrate ratio found in our energy chews offers significant advantages over the traditional 2:1 ratio. Here's how it works: A ratio of 1:0.8 enhances exogenous CHO oxidation compared with 2:1 ratio by 17% (O’Brien et al) and 10% (O’Brien et al)Although nutrition can be a challenge for a lot of runners, it’s key for performance. It is suggested that during endurance exercise (more than 2.5 hours) 80-120 grams of carbohydrate per hour should be consumed. What I like – and Jamie has said the same – is that it is very handy to eat less for a given amount of energy. As long I was getting one of these chews in along with a bottle of energy drink, I was fine to smash my way through a grim number of intervals. Fuel injected carbs Though it is important to note, 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. We have published groundbreaking science that challenges previous thinking about high carbohydrate & endurance nutrition – and how to fuel winning performances. The combination of maltodextrin and fructose, is the key to SiS Beta Fuel, as the transportation of nutrients across the intestinal wall is a rate limiting factor in carbohydrate oxidation during exercise. How does SiS Beta Fuel work?

Lemon: Sugar, Water, Glucose Syrup, Fructose Syrup, Gelling Agent (Pectin), Flavouring, Acidity Regulator (Citric Acid), Corn Starch, Glazing Agent (Coconut Oil, Carnauba Wax), Colour (Turmeric Extract). Orange: Sugar, Water, Glucose Syrup, Fructose Syrup, Gelling Agent (Pectin), Flavouring, Acidity Regulator (Citric Acid), Corn Starch, Glazing Agent (Coconut Oil, Carnauba Wax), Colour (Turmeric Extract). Generally, Wiener recommends consuming 1g of carbs per kilo of bodyweight every 60 minutes. So, if you weigh 80kg, aim for 80g of carbs per hour of exercise. O’Brien, W. J., Stannard, S.

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.As well as the Powder, the new SiS Beta Fuel range contains two different types of energy gels. The SiS Beta Fuel Gel contains 40 grams of carbohydrate also at the 1:0.8 ratio of maltodextrin to fructose in Orange and Strawberry and Lime flavours, with a second gel containing Nootropics, with the aim of giving you that mental boost during prolonged exercise. The SiS Beta Fuel gel contains 40g of carbohydrate also at the 1:0.8 ratio of maltodextrin to fructose. The SiS Beta Fuel gel with nootropics also contains 40g carbohydrate, but with cognitive enhancing nootropic compounds that give you that mental lift you might need, especially at the latter phases of exercise. Carbohydrate ingestion in the form of a carbohydrate-electrolyte solution in the first hour of running exercise, in comparison to just consuming water alone can delay time to fatigue by 15 minutes.
