Your kitchen faucet? That’s a solid source of electrolytes. Most municipal tap water contains small amounts of calcium, sodium, and magnesium—enough to keep your body humming along without any fancy bottles.
Is it a lot? Not really. Think of it as the baseline—like the standard level of caffeine in a cup of black coffee. It works, but it won’t win any competitions.
If you’re just chilling on the couch binge-watching your favorite show, tap water is totally fine. You don’t need a sports drink for that level of exertion—unless you’re sweating from laughing too hard at memes.
