Who drinks them?
Isotonic fluids are the most common drinks for athletes. They are particularly popular for middle and long distance runners.

How does my body deal with them?
The body prefers to use glucose as its source of energy. Sometimes it is better to consume isotonic drinks where the carbohydrate source is a concentrated form of glucose.
