Water Without Magnesium
Magnesium is one of the most important minerals found in natural waters, but some consumers seek waters with minimal magnesium — for taste, for coffee, or for specific dietary needs.
Magnesium in water
Naturally occurring magnesium contributes to water hardness alongside calcium. High-magnesium waters such as Donat Mg and Gerolsteiner are marketed for digestion and muscle recovery, while purified waters carry almost none.
Low-magnesium water options
Reverse osmosis and distilled bottled waters — Aquafina, Smartwater, LIFEWTR, Dasani — typically have less than 1 mg/L of magnesium. Soft natural waters like VOSS and Icelandic Glacial stay under 2 mg/L.
Taste impact
Magnesium gives water a slightly bitter, mineral edge above ~30 mg/L. Removing it produces a cleaner, neutral flavor often preferred for tea and light cooking.
Compare with highest-magnesium waters.
Frequently asked questions
Which bottled water has the least magnesium?
Aquafina, Smartwater, and LIFEWTR all sit below 1 mg/L of magnesium, making them the lowest-magnesium mainstream options.
Is magnesium-free water safe?
Yes — bottled water is not the primary source of dietary magnesium for most people. Leafy greens, nuts, seeds, and whole grains contribute far more.
