Mineral character

Calcium is 2 mg/L, magnesium 10 mg/L, sodium 1 mg/L, sulphate 4 mg/L, chloride 0 mg/L, and bicarbonate 6 mg/L. Hardness is 46 mg/L as CaCO₃ and TDS is approximately 23 mg/L. Magnesium exceeds calcium in this profile — an unusual inversion for a mountain water — reflecting the granitic geology of the source. Near-zero chloride and bicarbonate confirm a water with minimal geological contact.


Documented use and context

Sant’Anna is recommended and used in Italy for infant formula preparation. The Italian Ministry of Health classification for infant-suitable natural mineral waters requires sodium below 10 mg/L and nitrate below 10 mg/L; Sant’Anna meets both with significant margin, and the brand is listed for infant use under this classification. This attribution derives from the Ministry’s published classification rather than an independent academic citation.
