  24. Sengupta 2013 "Hard water has no known adverse health effect, WHO says at its Geneva Conference. In addition, hard water, particularly very hard water, could provide an important supplementary contribution to total calcium and magnesium intake. The health effects of hard water are mainly due to the effects of the salts dissolved in it, primarily calcium and magnesium."

    "Hypomagnesaemia is a common feature in subjects with type-2 diabetes (...) Recent evidence suggests that sub-clinical magnesium deficiency may precipitate a diabetic state."
