I am still highly sceptical about this and feel it is more of a "fear mongering" advertising - that this "remineralizing water" thing only started so that the RO filter businesses could create another source of recurring revenue. I also remember reading some study that said vitamins and minerals are better metabolised by our body as chemical compounds, as found naturally in food, than as individual elements in tablet forms. And that is why pharmaceutical companies have now started offering such compounds too - like Calcium + Zinc + Magnesium etc. Which also suggests that we may be better of with such vitamin and mineral supplements, if really required, than "remineralizing cartridges" which release questionable dosages into the water.
