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) 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. 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. 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.

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. Science in Sport energy chews deliver 46g of fast carbs in a tasty, convenient gummy bar which enhances output without leaving you feeling full and heavy.

In summary, the Science in Sport Beta Fuel range works by providing these two different forms of carbohydrate in a formula which can be simultaneously absorbed. This is key as the transportation of nutrients across the intestinal wall, which is a rate-limiting factor in carbohydrate oxidation during exercise. Something to also consider is the amount of caffeine you want in your energy source. Caffeine has been proven to boost mental and physical performance when undertaking Isotonic exercise, making it a great ingredient option. However, it is not necessary for everyone. So take your own health and needs into consideration. Beta Fuel works by providing these two different forms of carbohydrate which can be simultaneously absorbed. What’s new? 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. Our science-based solution, the combination of maltodextrin and fructose in an isotonic formula, is still 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.

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.I have been testing out the new range of BETA Fuel energy products from UK brand Science in Sport.
