FAQs

1. What does a carb and electrolyte supplement actually do?

It puts fuel and sodium in the same bottle. Carbohydrate fuels long sessions; sodium replaces some of what you lose in sweat. Carbohydrate-electrolyte solutions contribute to the maintenance of endurance performance during prolonged endurance exercise. Carbohydrate-electrolyte solutions enhance the absorption of water during physical exercise.

2. How is Carb + Electrolytes different from regular sports drinks?

Each scoop gives 30g of dual-source carbohydrate from a tri-blend of maltodextrin, highly branched cyclic dextrin and fructose, plus 250mg sodium. You scale it to the session: 1, 2 or 3 scoops for 30, 60 or 90g carbs.

3. Who should use a carb and electrolyte supplement?

Carb + Electrolytes is designed for endurance athletes, HYROX competitors, team-sport athletes, and anyone training longer than 60 to 90 minutes. Heavy or salty sweaters, or anyone training in the heat, may need extra sodium: pair it with Performance Hydration.

4. Does Carb + Electrolytes help with fatigue during long sessions?

Carbohydrate-electrolyte solutions contribute to the maintenance of endurance performance during prolonged endurance exercise. In practice, fuelling from the start of a long session helps delay fatigue and reduce performance drop-off in the back half. Start fuelling early rather than waiting until you fade.

5. What types of carbohydrates are used and why does that matter?

The formula includes maltodextrin, highly branched cyclic dextrin and fructose. Maltodextrin and cyclic dextrin provide glucose; fructose is absorbed through a different gut transporter. Two absorption routes allow more total carbohydrate to be absorbed at higher intakes than glucose alone.

6. When should you take Carb + Electrolytes?

It's designed for during sessions lasting over 60 to 90 minutes. You can also have it before or after long or hard training. Practise your fuelling in training before race day.

7. How much Carb + Electrolytes should you use per session?

The product is scalable. One scoop provides 30g of carbohydrate, with athletes able to increase to 2–3 scoops as session duration and intensity increase. This lets you match carbohydrate intake to training demands without overloading sodium. Build up to higher intakes in training.

8. Can Carb + Electrolytes replace gels and electrolyte powders or tablets?

For many sessions, yes. Carb + Electrolytes is designed to simplify fuelling by cutting down the need to juggle gels, salt tablets and guesswork. For the highest carb intakes or race day, pair it with Endurance Fuel Gels.
