The World Health Organization says, "There does not appear to be any convincing evidence that water hardness causes adverse health effects in humans."[6]
Some studies have shown a weak inverse relationship between water hardness and cardiovascular disease in men, up to a level of 170 mg calcium carbonate per litre of water. The World Health Organization has reviewed the evidence and concluded the data were inadequate to allow for a recommendation for a level of hardness.[6]
