Product Information

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. So, which should you try? Yet again, it boils down to personal preference, but here’s a rough guide: By using a precise balance of maltodextrin and fructose (1:0.8), rather than a single form of carbohydrate, performance improved with Science in Sport Beta Fuel, whilst avoiding any digestion issues. We have shown that athletes are able to tolerate 120 grams of SiS Beta Fuel per hour, significantly higher than the current recommended intake of 90gms per hour, with no stomach upset.

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.

Increase the percentage of ingested carbohydrate oxidised from 62% (2:1 ratio) to 74% (1:0.8 ratio) 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 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.

Let’s start the night before and ensure your glycogen stores are topped up. After dinner, I drink one serving of Maurten 320 Mix or two servings of Enervit IsoCarb. Some products also contain caffeine, which can help to give a mental and physical boost during the last hours of a race, while others contain electrolytes which help the body to stay hydrated.

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. 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.The combination of maltodextrin and fructose used in SiS Beta Fuel at a ratio of 1:0.8 provides a formula to enhance carbohydrate delivery and utilisation during exercise, whilst minimising gastrointestinal issues. For the Beta Fuel with Nootropics Gel we recommend consuming the nootropic gel during the latter phases of your exercise and 60 minutes prior to when you’d want to benefit from the performance effect, with a maximum of one serving per day. Part of an entire fuelling solution range that includes drinks and chew bars, our Beta Fuel Dual Source Energy Gel + Nootropics is optimised with a brand new 1:0.8 ratio of 40g carbohydrate to enhance your mental and physical power output, increase your body's carbohydrate usage efficiency, and limit gastrointestinal discomfort to deliver a scientifically superior fuel.

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.
