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.
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 McGregor recommends consuming 30-60g of carbs per hour for the first three hours of running, increasing to 60-90g of carbs per hour if you’re still going after that. This can be in the form of gels, drinks or solids.

Biological psychology, 77(2), 113-122. For those who like to consume gels whilst running, the SiS Beta Fuel Gel with Nootropics could be a game changer during that last push. Ideal for when you are in the last quarter of your marathon, you know the end is near, it is all going to be worth it, but your physically and mentally exhausted and in need of a boost to help give you that push to the finish.
A ratio of 1:0.8 increases % of ingested CHO that was oxidised (efficiency) from 62% (2:1) to 74% (1:0.8) (O’Brien et al) Our new SiS Beta Fuel formula is leading a revolution in endurance fuelling by using an optimised ratio of maltodextrin to fructose, providing a science-based complete fuelling solution for runners. This depends on the type of exercise you’re doing. Whether it’s HIIT, endurance or strength training, the timing of your fuelling will differ. Generally, it’s a good idea to take your supplement just before your session if it’s high intensity, while long distance running or similar endurance exercise may benefit from intra workout supplementation. You could use energy powders, gels or even gummies during longer or more intense exercise sessions. The new SiS Beta Fuel Powder solution contains 80 grams of carbohydrate at this 1:0.8 ratio, in a neutral pH formula still maintaining the signature isotonic format to minimise gastrointestinal issues. The Powder is available in Orange, Strawberry and Lime and Red Berry flavours. So as runners, we need to be consuming both adequate carbohydrate whilst also staying hydrated to perform at our best and hopefully avoid gastrointestinal issues.

The SiS Beta Fuel Gels and Chews can also be used for running, preference will come down to the individual with some people relying on gels, whilst others prefer more ‘food’ like textures, such as the chews. 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 Jeukendrup A.E.

For training and competition of 2 – 2.5 hours or more, SiS Beta Fuel is the next generation of endurance fuelling. These results have never been seen before and change everything we thought we knew about endurance fuelling guidelines. 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. Got this today…wow if I ate all that before a big ride or race and after it would cost more than big race entry fees. Not to mention I would probably gain weight. 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. 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.

Increase the percentage of ingested carbohydrate oxidised from 62% (2:1 ratio) to 74% (1:0.8 ratio) It is suggested that during endurance exercise (more than 2-2.5 hours) 80-120 grams of carbohydrate per hour should be consumed to maintain blood glucose levels and prevent fatigue. 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

Medicine & Science in Sports & Exercise, 45(9), 1814-1824. I have been testing out the new range of BETA Fuel energy products from UK brand Science in Sport. They are tasty, easy to take onboard, and a notable scientific development over their predecessors and many other energy products on the market. Here's the low-down… Remember, as a runner, you are still an individual. Both in preferences of fuel (i.e., liquid, or solid) and how much carbohydrate your body needs depending on body weight. Because there’s such a plethora of energy products available, try a few and see how they sit with you. “Once you find something you like, I’d suggest training with it consistently. This will help your body adapt to its usage and lessen the risk of digestive issues at critical moments.” How We Test 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.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? The Science in Sport Beta Fuel range provides a variety of performance solutions to choose from to build your ultimate nutrition strategy. You might already have used our SiS Beta Fuel Powder, so other than having new SiS Beta Fuel options in Gels and Chews, what is different about it? 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. 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.
