Why this certification matters
- Informed Sport
- Informed Sport certification is especially relevant for athletes in tested sports because products are batch-tested for substances prohibited in sport.
Frequently asked questions
- What does 'dual source' mean in Beta Fuel?
- SiS's Beta Fuel range is built on a dual-carbohydrate blend — maltodextrin plus fructose — which research suggests allows higher carb absorption per hour than a single-carb gel. Check SiS's published carb-per-serving figures on the pack for the exact split.
- How is Beta Fuel different from SiS GO Energy gels?
- GO Energy is the older, lighter-carb gel and powder line. Beta Fuel is positioned higher up the carb-per-serving ladder for longer endurance work. We list the GO and Beta Fuel lines separately.
- Where is Beta Fuel sold in the UK?
- Amazon UK lists the gel multi-pack at £43. SiS also retail direct and via specialist endurance shops; we surface listings as they come in.
- Is Beta Fuel suitable for tested athletes?
- Yes — the dual-source gel is Informed Sport certified, meaning every batch is screened against the WADA banned-substance list.
- Is Beta Fuel just for long-distance work?
- It's positioned for endurance and high-intensity events where higher per-hour carbs matter. For shorter sessions, a lower-carb fuel from SiS's GO range is often sufficient.
