Seltzer water—also called sparkling water or carbonated water—is a fizzy favorite for many looking to replace sugary sodas or spice up their hydration routine. But is it actually good for you?
Here’s what science and doctors say:
✅ The Benefits
- Better Hydration
If you find plain water boring, seltzer can help you stay hydrated without extra sugar or calories. - May Help Digestion
Carbonation may ease indigestion or bloating in some people by stimulating swallowing and mild stomach movement. - No Sugar, No Calories
Unlike soda, plain seltzer has zero sugar, zero calories, and zero additives—just water and carbon dioxide.
⚠️ The Potential Downsides
- Can Irritate Sensitive Bladders
If you have conditions like interstitial cystitis or an overactive bladder, carbonation may make symptoms worse. Listen to your body. - May Affect Dental Health (Slightly)
Seltzer is slightly more acidic than still water. While much less harmful than soda, frequent sipping could erode enamel over time. Use a straw and avoid brushing immediately after. - Watch the Additives
Flavored seltzers sometimes sneak in citric acid, sweeteners, or sodium. Read labels if you’re sensitive or watching your intake.
👩⚕️ Bottom Line
For most people, seltzer water is a safe and healthy alternative to sugary drinks. Just keep an eye on how your body reacts—especially your bladder and teeth.
