Water Without Calcium
Calcium contributes to hardness and mineral taste. Some consumers prefer bottled waters with minimal calcium content — for taste, for coffee brewing, or for medical reasons.
What calcium does
Calcium is the most abundant mineral in the human body and supports bone density, muscle contraction, and nerve signaling. In water it contributes to hardness and a chalky mouthfeel above ~80 mg/L.
Who may prefer low-calcium water
People on calcium-restricted diets, those prone to kidney stones (under medical guidance), espresso enthusiasts protecting their machines, and anyone who finds high-mineral water taste too heavy.
