Nootropics are supplements that can improve or maintain peak cognitive performance such as attention, focus, creativity, motivation, memory and so on. We've combined our innovative Beta Fuel Energy Gel with nootropics to offer endurance athletes a complete energy source for both body and mind because you need peak mental function when the demands are most physical. A 1:0.8 ratio of maltodextrin to fructose reduces self-reported symptoms of stomach fullness when compared with a ratio of 2:1 A 1:0.8 ratio of glucose 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 While gels are easy to carry, some runners prefer to consume carbohydrate drinks, which help to maintain hydration, preventing the need to carry/consume additional drinks, and are often easier on the stomach.

HIGH5 Energy Gel (20 x 40g)

It takes around 500g of carbohydrate to fill your glycogen stores and, at most, this will last you for 60-90 minutes of running at 55-75 percent of your maximal heart rate,' explains leading sports dietician Renee McGregor. 'The faster you go, the sooner your stores will deplete.' 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. Designed as a world-leading, whole body energy source, our innovative Beta Fuel Dual Source Energy Gel + Nootropics combines a new ratio of carbohydrate with Cognizin® Citicoline to improve both your physical and mental performance. Nootropics are substances that can enhance cognitive performance giving you that mental lift you might need. So, as well as 40 grams carbohydrate, 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.

Energy drinks: Ideal during the summer months for topping up your carbs while hydrating your body on the go. Lugging a bottle around a long course can be a hassle, though. 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. 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.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. 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. 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

(2013). Fructose–maltodextrin ratio governs exogenous and other CHO oxidation and performance. Medicine & Science in Sports & Exercise, 45(9), 1814-1824.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. Completing our fuelling solution is the SiS Beta Fuel Chew Bar. We know that during endurance exercise, being able to vary your fuelling choices is important. Within the new SiS Beta Fuel range, we are providing you with even more choice without compromising on quality or taste, meaning you can maintain optimal sources of energy. These chews are in a unique format to SiS, being super easy to consume and available in Orange and Lemon flavours. In the first study of its kind, we tested feeding athletes 120g of Science in Sport Beta Fuel per hour, singularly, and combined across our patented range of gels, chews and drinks. The previously recommended intake for endurance fuelling was 90g per hour. Through our Performance Solutions team, we have worked closely with elite athletes in the research and development of the new Beta Fuel range to bring you a scientifically superior fuel in a range of formats that allow you to use +17% more carbohydrate (O’Brien et al, 2013).

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. A great way of being able to access nutrition during running is using hydration vests. You can use these vests to carry water mixed with a SiS Beta Fuel Powder, in a flavour of your choice (Red Berry, Strawberry & Lime or Orange). The SiS Beta Fuel Powder also contains sodium which is key for staying hydrated.The new Beta Fuel range has a change in the ratio of maltodextrin to fructose to 1:0.8. In comparison to the (still highly scientifically impressive) 2:1 ratio, the 1:0.8 ratio has been proven to: O’Brien, W. J., Stannard, S. R., Clarke, J. A., & Rowlands, D. S. (2013).
