Frequently asked questions
Why is Gerolsteiner’s pH below 7?
Naturally carbonated waters dissolve CO₂ into carbonic acid, which lowers measured pH. Gerolsteiner’s very high bicarbonate content buffers this in the body.
Is Gerolsteiner good for bone health?
It is one of the highest-calcium bottled waters available, but we make no medical claims — talk to a clinician about your individual needs.
