Objective: To describe the calcium concentration of tap and bottled waters from Argentina and to estimate thecontribution of drinking water to calcium recommendations.Results: Calcium concentrations provided by water authorities ranged from 6 to 105 mg/L. The mean calciumlevel of samples analysed at the Laboratorio de Ingeniería Sanitaria, National University of La Plata was 15.8(SD ± 13.2) mg/L and at the Bone Biology Laboratory of the National University of Rosario was 13.1 (± 10.0) mg/L.Calcium values of samples from supply systems and private wells was similar. Most bottled waters had calcium levelswell below 50 mg/L. The intake of one litre of drinking water from Argentina could represent in average between 1.2and 8.0% of the calcium daily values for an adult.Keyword: Bottled water, Calcium intake, Drinking water
