Hypotonic or hypotonic are beverages whose osmotic pressure is lower than that of blood (<290 mosmol/l). They have a hydrating effect because more liquid flows into the cell wall than out. They are particularly good for absorbing fluids and can also supply the body well with minerals, carbohydrates, etc.

Manufacturers such as Sponser now rely predominantly on hypotonic blends for sports drinks.

See also isotonic, hypertonic.
