SIS Beta Fuel Energy Chews

As an endurance athlete, whose body is under strain for periods typically longer than two hours, you need to take in 80–120g of carbohydrates per hour to ensure a high-quality, competitive performance. Science in Sport Beta Fuel Dual Source Energy Chews provide 46g of fast-acting carbohydrates in a convenient and tasty chew. The 1:0.8 ratio of glucose to fructose increases the percentage of ingested carbohydrates that are oxidised (known as efficiency) from 62% to 74% compared to a 2:1 ratio. Compared to a 2:1 ratio, the 1:0.8 glucose to fructose ratio reduces symptoms of stomach fullness, improves performance, and increases carbohydrate utilisation efficiency without gastrointestinal discomfort.
