You’ve heard this one, right? “Fizzy water pulls calcium out of your bones!” This rumor comes from studies on soda. Specifically, cola. The phosphoric acid in cola might affect bone density over decades of abuse.
Seltzer doesn’t have phosphoric acid. It has carbonic acid, which is incredibly weak. Your stomach acid is literally thousands of times stronger. Your bones are safe. You are not turning into a brittle biscuit.
Does La Croix Hydrate You? (Seltzer, Sparkling Water)
So please, pop open that can. Your skeleton won’t crumble. I promise.
When Seltzer Fails (It’s Rare, But Honest)
Okay, one scenario where seltzer is not the champion. Intense exercise. Like, you just ran a marathon in the desert and sweating is your new full-time job.
Seltzer can make you feel bloated. Burping during a sprint is awkward and unpleasant. And you lose electrolytes when you sweat. Flat water with a pinch of salt is actually better here.
But for your average Tuesday? Sitting on the couch, slightly thirsty? Seltzer is a legend. It’s hydrating, refreshing, and honestly, way more fun than staring at a glass of tap water.
