How is OS-1 different from sport drinks?
Oral Rehydration Solution OS-1 is used in dietary therapy (oral rehydration therapy) for dehydration.
It contains more electrolytes than sports drink and less sugar to facilitate absorption of water and electrolytes.

Sports drinks are sufficient for replenishment of water and electrolytes after everyday activities. However, OS-1 oral rehydration solution is appropriate for mild to moderate dehydration in circumstances such as the following.
- Dehydration associated with diarrhea, vomiting, or fever due to infectious enteritis or the common cold
- Dehydration due to inadequate oral intake in the elderly
- Dehydration due to excessive perspiration
- Heatstroke associated with dehydration
- OS-1 Jelly can be used by people with trouble chewing or swallowing
