What is "isotonic"?

Isotonic is a term used to describe a type of drink or beverage that has a similar concentration of dissolved particles, such as salt and sugar, as the body's fluids. This means that isotonic drinks can be quickly absorbed by the body and can help to rehydrate and replenish lost electrolytes after physical activity or illness. Isotonic drinks are often consumed by athletes or individuals who engage in strenuous exercise, as they can help to maintain hydration levels and improve athletic performance. Isotonic drinks are also commonly used to treat dehydration caused by illness or diarrhea, as they can help to replace lost fluids and electrolytes. .
