I have made the electrolyte mistake as well. I look at it like natural water (pre stripped) has the basic electrolyte minerals...even sodium. I do supplement with these as well but regularly. I have read different things but personally much enjoy having the correct electricity in my body :)
Let me add as well I do coffee enemas when I fast which are highly mineral intensive in making Glutathione which is the natural healing agent (free radical scavenger etc).
