Low Iodine Classic Grapefruit Sparkling Water

Bright, citrusy, and genuinely refreshing, this sparkling grapefruit drink is the kind of thing you'll want to keep in a pitcher in the fridge all week. A quick homemade syrup made from real grapefruit juice and zest gives it a depth of flavor that no store-bought soda can match. The syrup comes together in just a few minutes on the stovetop — no boiling required — and once it's strained and chilled, you simply pour it into sparkling water for an effervescent, lightly sweet sip. For anyone navigating iodine restrictions, this recipe is a natural fit: it's built entirely from fresh fruit, plain sugar, and water, with zero processed additives or iodized salt to worry about. Grapefruit's natural tartness balances the sweetness beautifully, so it never tastes cloying. Serve it over ice with a fresh grapefruit wedge on the rim and it looks as good as it tastes — effortlessly elegant for a weekday afternoon or a casual gathering.
