Top Zero-Calorie Sparkling Waters (2026)
1) Waterloo Sparkling Water — Best Overall Flavor Profiles
Bold, aroma-forward flavors with zero calories, zero sugar, and no sweeteners; also Non-GMO Project Verified and Whole30 Approved. For the deep dive, see our brand page:
Waterloo Sparkling Water. The official brand page confirms 0 calories/sugar and no sweeteners.
2) LaCroix — Widest Flavor Range
The category staple: 0 calories, 0 sodium, no artificial sweeteners. Great everyday cans; frequent seasonal drops.

Crisp flavors, grocery-store easy, and 0 calories. PepsiCo product facts list 0 mg caffeine for classic flavors like Lime and Raspberry.
4) AHA — Clean Taste; Some Flavors Have Caffeine

Family-made since 1882; calorie-free, often sodium-free, and famous for inventive seasonal flavors.
6) Topo Chico (Sparkling Mineral Water) — Sharp Bubbles, Mineral Bite

8) S.Pellegrino Essenza — Subtle Aromas, 0 Calories
The gentle S.Pellegrino bubbles with Mediterranean aromas; zero calories and no sweeteners.

Zero Calories Doesn’t Mean Zero Contaminants
Calorie count is the easy part — every brand above delivers on that. The harder question is what else is in the can. Consumer Reports’ lab testing found 7 of 12 carbonated waters exceeded 1 part per trillion of total PFAS (“forever chemicals”), and the spread between brands was large.
| Brand | Total PFAS (ppt) | Calories |
|---|---|---|
| S.Pellegrino | 0.31 | 0 |
| Perrier | 1.10 | 0 |
| LaCroix | 1.16 | 0 |
| bubly | 2.24 | 0 |
| Topo Chico | 3.9 (was 9.76) | 0 |
| Polar | 6.41 | 0 |
For context: the EPA’s 2024 enforceable limit is 4 ppt for PFOA and PFOS individually, and the FDA’s April 2025 survey of 197 bottled water products found none exceeding EPA limits. So none of these are unsafe by regulatory standards. But if you drink several cans a day and want the lowest measured exposure, S.Pellegrino and Perrier are the better picks — and Polar is the one worth reconsidering. Full data: every bottled water brand ranked by PFAS.
Label Tips: How to Verify 0 Calories
- Ingredients: Look for carbonated water + natural flavors (or just sparkling mineral water).
- Nutrition Facts: Calories 0; Sugars 0 g; Sweeteners absent. If you see juice, agave, or stevia—likely not zero.
- Caffeine callouts: Some lines (AHA select, bubly “Bounce”) add caffeine—fine if desired, but not for late-night sipping.
- Sub-lines differ: Topo Chico Sabores and Liquid Death soda-flavored have calories; choose their classic sparkling variants for 0.
Best Time to Drink + Use Cases
- All-day hydration variety: Rotate with still water to stay engaged.
- With meals/snacks: Carbonation boosts flavor perception and satiety.
- Post-workout (light/moderate): Refreshing zero-sugar option; add salty foods if you sweat heavily.
- Late evening: Choose non-caffeinated cans for sleep-friendly fizz.
