I use a combination of sea salt and low sodium salt. I used to use grey atlantic sea salt more, but it does not go through a salt seller very well at all, and has become too expensive for our needs now.
I recently went over to low sodium salt becauses it has potassium in it, something I am routinely low in (when blood tests are done) where as I am sodium sensitive (not helped by my childhood GP & dentist getting my mother to make me wash my teeth in salt due to an inability to use any of the toothpaste brands at the time). In addition it is better for me becuase of my inability to balance sodium/potasium correctly due to my reduced adreanal gland function.
But I prefer the atlantic grey salt - it is basically unprocessed and less salty than sea salt (don't ask - you just have to try it).
I have been considering trying the himalyan rose salts but the cost puts me off - even my prefered salt is cheaper.
