Sodium in mineral water
Plain sparkling mineral water typically contains very little sodium — far less than club soda or any flavored option. Avoid any sparkling water with added sodium bicarbonate if you are watching sodium.
Lowest Sodium Sparkling Waters
Most sparkling mineral waters are naturally low in sodium, but a few sit notably lower than others. Useful if you are managing blood pressure or following a low-sodium diet.
Low sodium rankings
| Brand | Sodium (mg/L) |
|---|---|
| Perrier | ~9 |
| Topo Chico | ~50 |
| San Pellegrino | ~31 |
Dietary considerations
A typical 1.5L day of Perrier contributes ~14 mg of sodium — well under 1% of the 2,300 mg daily limit. Borjomi, by contrast, contains over 1,000 mg/L of sodium; avoid it on a low-sodium diet.
Avoid these on low-sodium diets
- Borjomi (~1,200 mg/L sodium)
- Most club sodas (added sodium)
- Vichy Catalan (very high sodium)

Which sparkling water has the lowest sodium?
Perrier — about 9 mg per liter, among the lowest in the naturally sparkling category.

Most are excellent options — just avoid Borjomi, Vichy Catalan and club sodas.
Does carbonation add sodium?
