We’ve heard that coffee dehydrates you, right? And soda is a nightmare for hydration. So it’s easy to lump seltzer in with the bad kids. But that’s lazy thinking.
Seltzer Water Hydrate You at Peter Dumas blog
Let’s compare. A can of cola has sugar, caffeine, and phosphoric acid. Those things can mess with your body’s fluid balance. Seltzer? Zero sugar. Zero caffeine. It’s just water and a little attitude.
The only ingredient that matters is the water. And it’s all there. All of it. Ready to hydrate your soul.
What About Flavored Seltzer? Trick Question!
You grab a grapefruit-flavored one. Is that still good? Mostly, yes. The “natural flavors” add trace amounts of organic compounds. Not enough to make your body freak out.
The tiny concern: some flavored seltzers have citric acid. That’s fine for hydration, but rough on your tooth enamel if you sip them all day. Don’t brush your teeth immediately after drinking one—you’ll brush that acid into your enamel like sandpaper.
But for hydration? It’s still a win. You’re getting water. You’re getting flavor. You’re not getting a sugar crash. Your kidneys will thank you.
