Still water (spring, mineral or treated) that is carbonated with CO₂, either naturally or artificially.

What it contains

  • Same minerals as the base water

Benefits

  • A refreshing, sugar-free alternative to soft drinks
  • Aids hydration for those who prefer fizz

Cautions

  • Can cause bloating in some
  • Avoid versions with added sugar/sweeteners
