Resumen: Introduction: An appropriate magnesium intake has proved to have beneficial effects on bone health, reduce insulin resistance and prevent atherosclerosis. Objective: To determine the concentration of magnesium in drinking water and bottled mineral water in Spain and assess its daily contribution to dietary recommendations. Methods: We used ion chromatography to analyse the magnesium concentrations of public drinking waters in a representative sample of 108 Spanish municipalities (supplying 21,290,707 potential individuals) and 109 natural mineral waters sold in Spain (97 Spanish and 12 imported). Results: The water generally contained between 15 and 45 mg/L of magnesium, but in seven municipalities it contained over 45 mg/L. The average magnesium concentration of 97 brands of Spanish natural mineral water was 16.27 mg/L (range: 0.11-141.2 mg/L). Of these, 33 contained between 15 and 45 mg/L of magnesium and four contained over 45 mg/L. Of the 12 imported brands, 4 contained over 45 mg/L. Assuming water consumption is as recommended by the European Food Safety Agency, water containing 15 to 45 mg/L of magnesium provides between 9 and 76.5% of the recommended intake of magnesium for children aged one to thirteen, up to 25.7% in adolescents, between 7.5 and 25.7% for adults, and up to 27% for lactating women. Water with 60 mg/L of magnesium provides between 30 and 102% of the recommended dietary allowance, depending on the age of the individual. Discussion: The consumption of public drinking water and natural mineral water in a third of Spanish cities can be regarded as an important supplementary source of magnesium. © 2015 Grupo Aula Medica S.A.
