The Beta Fuel powder is our scientifically superior fuelling option designed for endurance providing high carbohydrate in an easily digestible formula. With an optimised ratio of Maltodextrin to Fructose (1:0.8), Beta Fuel provides 80g of carbohydrate in a single convenient isotonic formular with minimal risk of GI discomfort to maintain optimal performance. 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.
As we explain in our in-depth guide to cycling nutrition, your liver and muscles can only store a certain amount of glycogen, enough for around one to two hours of work depending on how trained you are. If you were to continue to exercise beyond that limit without refuelling, the result - the bonking mentioned earlier on - will not only affect your ability to push on the pedals, but your cognitive ability too, with symptoms including nausea, extreme physical weakness, poor coordination, and dizziness. A 1:0.8 ratio of maltodextrin to fructose increases the percentage of ingested carbohydrate that is oxidized (known as efficiency) from 62% to 74% when compared with a ratio of 2:1 Haskell, C.

Biological psychology, 77(2), 113-122.As part of the 2022 Runner’s World Sports Nutrition Awards, we enlisted a 200-strong panel of testers – made up of ordinary runners and experts – to slurp and munch their way through a variety of market-leading energy gels, drinks and chews to find the best on the market. BETA Fuel DrinkFirst launched in 2018, the original Science in Sport Beta Fuel drink was an isotonic product using both maltodextrin and fructose at a ratio of 2:1 to optimise carbohydrate delivery and utilisation during exercise, while minimising gastrointestinal issues.
Our GO Isotonic Energy Gel is simply 22g of carbohydrate from our selected source of maltodextrin. This creates an isotonic formula, which causes minimal stomach discomfort during exercise, but with maximum energy absorption. USAGE: O’Brien, W. J., & Rowlands, D. S. (2011).

Increase the percentage of ingested carbohydrate oxidised from 62% (2:1 ratio) to 74% (1:0.8 ratio)Both deliver you the energy you’re going to need for any endurance sport, but there are some slight differences between the two. Putting these two powerhouse endurance nutrition gels side by side should help you to find out which one is right for you. In simple terms, nootropics are substances that can enhance cognitive performance giving you that mental lift you might need, especially at the latter phases of exercise. So, as well as 40 grams carbohydrate at the 1:0.8 ratio of maltodextrin to fructose, the SiS Beta Fuel Gel with Nootropics contains 1 gram of the amino acid L-taurine, 250 milligrams of Cognizin® to enhance information processing and 200 milligrams of caffeine with 200 milligrams of L-theanine, the amino acid which has been shown to increase subjective feelings of alertness, while reducing feelings of ‘jitters’ that you get with caffeine alone. The right combination of nutrition for running is a common challenge for most. As a runner, we have all been there, when your stomach starts churning you cannot focus on enjoying your run whether this is during training or a race. Testing the best energy gels is a much more involved process than simply eating them all in one sitting and giving myself hyperglycaemia.
