What is an isotonic sports drink?

An isotonic sports drink is a beverage designed to hydrate the body and replenish electrolytes lost during physical activity. It is formulated to match the concentration of particles (mainly sodium and potassium ions) in the blood, allowing for quick and efficient absorption of water and nutrients into the bloodstream. Isotonic drinks help maintain fluid balance and electrolyte levels in the body, preventing dehydration and promoting optimal performance during exercise or sports activities.
