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
- Does it contain carbohydrate or just electrolytes?
- Both — it's a fuelling drink as well as a hydration one, with around 36 g of carbohydrate (maltodextrin and fructose) plus electrolytes per 500 ml. That distinguishes it from zero-calorie electrolyte tablets.
- How do I mix it?
- SiS suggests 40 g (two scoops) in 500 ml of water, drunk roughly every 45–60 minutes of exercise. The maltodextrin-fructose mix is designed for absorption without stomach upset.
- What electrolytes does it provide?
- Sodium, potassium, calcium and magnesium, alongside the carbohydrate. Sodium is the main electrolyte lost in sweat and the reason for the salt content.
- Is it certified for banned substances?
- Yes — Informed Sport, with each batch screened against the WADA banned list, which matters for tested endurance athletes.
- Is it sugar-free?
- No — it's a carbohydrate fuelling drink, so it isn't low-carb; it's sweetened with aspartame in addition to the carbohydrate. Check the label if you're watching carbohydrate intake.
