Hypertonic Drinks

Definition

Hypertonic drinks contain higher concentrations of salts and sugars than found in the human body, more than isotonic drinks. They are used to provide energy but are less focused on hydration.

Scientific / Technical Definition

Hypertonic drinks are beverages that have a higher osmolarity than body fluids, meaning they are more concentrated with solutes like glucose and electrolytes. These drinks increase the concentration gradient, causing water to move from body tissues into the gastrointestinal tract, which can have implications for both hydration and energy replenishment.

Benefits

• Provide a rapid source of energy due to high carbohydrate content.
• Can be beneficial for athletes during long-duration activities or recovery phases where quick energy replenishment is needed.

Examples

• Certain sports drinks designed for endurance activities
• Coconut water with added sugars
• Cola beverages

Additional Information

• Side effects: Frequent consumption can lead to dehydration if not accompanied by adequate water intake, as the high concentration draws water into the gut. They are also not ideal for quick rehydration after intense exercise.
