Is just Himalayan rock salt enough electrolytes for an extended fast?

Not sure if this group includes 7 day fasts, but im about to start my first and im wondering how I’m going to make sure im getting enough sodium magnesium and potassium. Is pink salt enough to supplement all of these or should i be using electrolytes packs. Want to make sure im doing this safely. via /r/intermittentfasting https://ift.tt/4IkbKXm https://ift.tt/TbJK57G
