Not all seltzer is created equal. Have you ever read the label on a can of club soda? It might have added minerals like sodium. A little salt can help you retain water, which is actually great for hydration. So club soda might be even better than plain water. Mind blown.
But watch out for flavored seltzers. Some are sweetened with sugar or artificial junk. That stuff can mess with your gut and make you feel bloated. Stick to the unsweetened stuff. Your body wants bubbles, not a chemistry experiment.
Here’s a funny detail: In a 2013 study, athletes who drank sparkling water after a workout rehydrated just as well as those who drank still water. The only difference? The fizzy group reported feeling “fuller.” And they probably burped a lot more. Hydration win.

But What About Your Bones?
You’ve probably heard the old wives’ tale: “Sparkling water leaches calcium from your bones!” Let me stop you right there. That rumor comes from cola, not seltzer. Cola has phosphoric acid, which can mess with calcium. Plain seltzer? It’s innocent.
A 2026 study found no link between sparkling water and bone density loss. So unless you’re chugging six liters of cola daily, you’re fine. Your skeleton isn’t going to crumble because you like a little fizz. Drink that LaCroix with reckless abandon.
Wait—does seltzer make you fart? Yes. Yes, it does. The carbonation can cause bloating and gas. That’s the price you pay for being a fancy, hydrated human. But here’s the good news: That gas has to leave your body somehow. So you might be bubbly in more ways than one.
