Quick verdict by goal

  • Rehydration that matters (illness, heat, heavy sweat): DripDrop. Its ORS-style formula (sodium + glucose at an absorption-optimized ratio, low osmolarity) is designed to pull fluid in faster than water or typical sports drinks.
  • Low-calorie, low-sugar daily hydration: Nuun Sport. It’s light, portable, and keeps sugar/carbs minimal while still delivering a solid 300 mg sodium per tablet.
