Lowest Sodium Water Brands
For people on low-sodium diets — or anyone who simply wants a cleaner taste — these bottled waters report the lowest sodium content widely available.
Why sodium matters
Excess sodium contributes to higher blood pressure in salt-sensitive individuals. Most bottled waters add only trace amounts, but mineral and sparkling waters can carry significantly more.
Sodium in bottled water
Purified waters like Aquafina and Smartwater typically report under 5 mg/L of sodium. Spring waters like Evian sit around 5–7 mg/L. Mineral waters can range from 10 mg/L up to several hundred mg/L (Vichy Catalan, San Pellegrino).
Best low-sodium waters
Aquafina (~0 mg/L), Smartwater (~0 mg/L), Dasani (~7 mg/L), VOSS (~6 mg/L), and Evian (~6.5 mg/L) consistently rank lowest among major bottled brands.

Frequently asked questions
Which bottled water has the lowest sodium?
Aquafina and Smartwater report essentially zero sodium, since both are purified through reverse osmosis or distillation with minimal mineral re-addition.
Is Evian low in sodium?
Yes — Evian contains about 6.5 mg/L of sodium, well below most mineral waters and considered low-sodium.
Does sparkling water have more sodium?
Often yes. Many sparkling mineral waters (San Pellegrino, Vichy Catalan, Perrier) contain higher sodium than still purified waters. Always check the label.
