A hypotonic sports beverage is characterized by a lower solute concentration compared to another solution. These drinks contain a reduced percentage of carbohydrates, making them suitable for athletes who require higher fluid intake with a lower carbohydrate content. Typically, hypotonic beverages contain less than 6% carbohydrates.
Hypotonic drinks exhibit lower levels of salt and sugar than the human body, facilitating a swift replenishment of fluids lost through sweating. The low sugar content is advantageous, as fluid absorption primarily occurs in the small intestine and requires some glucose. Consequently, fluids in hypotonic drinks are absorbed into the bloodstream at an accelerated rate, ensuring rapid hydration and electrolyte release. However, they offer lower carbohydrate amounts per unit volume.
Prominent examples of sports and electrolyte drinks currently marketed as hypotonic include Hydralyte Sports, Mizone, SOS Hydration Drink Mix, G Active, G2, and Powerade Zero.
