Natural alkaline water comes from springs where it picks up minerals from rocks. This type usually has very low sodium—like a whisper of salt, not a shout.
Artificial alkaline water, the kind made in a factory, can have added minerals. Some brands add sodium bicarbonate (baking soda) to boost the pH, and that’s where the sodium sneaks in.
Next time you’re at the store, flip that bottle over and check the label. You might be surprised by how much—or how little—sodium is hiding inside.
How Much Sodium Are We Talking?
For most brands, we’re looking at something like 10 to 30 milligrams per liter. That’s roughly the same as a small pinch of salt on your dinner plate.

Compare that to a can of soda, which can have 40-50 milligrams or more. Alkaline water is still a low-sodium superhero compared to your favorite fizzy drink.
Unless you’re on a strict doctor-ordered low-sodium diet, that tiny amount won’t matter. It’s more of a fun fact than a health warning.
