Most of the bottled water in this country has NOT had all minerals removed. In fact, most of it is just spring water. The only thing you are buying that is different than ordinary tap water is that is does not have chlorine and fluoride added. We own some property about a mile from where one of the better known brands is pumped out of the ground. Our well could be the same water.
I was basing my comments on someone who’s dehydrated almost to the point of collapse. EMT’s use an electrolyte based re-hydration.
Yeah, I watched "How it's made" on the Science Channel.
