Totally agree with plonkster. I never worry about my water lacking minerals. A balanced diet takes care of that, not water. Which is why a RO countertop water filter is the optimal choice, preferably with pre-filters for precaution. The APEC RO-CTOP is probably the best option at the moment. I found it on healthy kitchen 101 or something. Can’t recall. Look up the filter yourself to see if it has what you’re looking for. Best of luck.
