What are hypertonic drinks?
Hypertonic drinks are used to supplement your daily carbohydrate intake. They contain even higher levels of carbs than isotonic and hypotonic drinks.

When should I drink them?
The best time to drink them is after exercise as they help your body to top up on muscle glycogen stores. These are your valuable energy stores.

In very long distance events such as marathons, high levels of energy are required.

Can you drink them during exercise?
Yes. Hypertonic drinks can also be taken during exercise to meet the energy requirements.

However, it is advisable to only use them during exercise alongside isotonic drinks to replace fluids.
