I’ve met some opinions that the best option is pink himalayan salt. Content of trace amounts of elements in it after put it to a water makes that that body read it as a ,,food” not something to flush a body out of elements.
This kind of salt has formed under huge pressure that makes elements been captured in to regular crystal structure.
Not sure if there’s any science behind.
