I also use salt with my food, I just don't think of that as a "supplement" in the same way as I take the other minerals.
People who don’t eat junk food often don’t get enough salt.
Specific symptoms of deficiency are leg cramps, dizziness on standing , passing urine during the night and craving salty foods like olives and pickles.
