Seltzer water is, in its purest form, just water that has had carbon dioxide gas dissolved into it under pressure. That’s it. No sugar, no artificial colors, no secret clown tears—just H₂O with a party trick.
So, from a hydration standpoint, your body doesn’t care if the water arrives flat from a tap or bubbly from a can. Your kidneys are not snobs. They’ll happily process that fizzy goodness just like they would a glass of still water.
But wait—doesn’t the carbonation mess with my insides?
You might have heard the rumor that seltzer is bad for your teeth or your bones. Let’s bust that myth with a gentle, bubble-popping sound. The acidity in seltzer is very mild—way less acidic than soda, fruit juice, or even that lemonade you chugged last weekend.
Your enamel isn’t going to dissolve into a sad puddle because you enjoy a few fizzy sips. Unless you’re swishing the stuff around your mouth like mouthwash for hours on end, you’re fine. Drink up.
And the bone thing? That rumor comes from cola and phosphorus, not from plain seltzer. Seltzer won’t make your skeleton crumble into a pile of dust. I promise.
