Think:

1) Look at the volume of water you consume in a day vs the volume of salt

2) There are no minerals in any salts that have such a minute daily requirement that you can reach that requirement by using a small amount of salt. You WILL meet those requirements, and then some, with proper food intake

Salt is seasoning, nothing more. Trying to decide on a salt to use based off of its alleged mineral content is a waste of time, energy, and possibly money.
