Eli5: how did humans get salt before modern means of transportation

Question

The human body needs salt to function properly, but surely First Nations of the prairies, people of central Africa or of Central Europe, from the Mongolian steppes and from other landlocked places, couldn’t have access to salt marshes. So where did they get it from?

Answer 1

It’s simple : using the old means of transportation. Also, relying on salt mines rather than salt marshes. There are historical records of salt mines and boats/land caravans transporting them all around Europe and Northern Africa. I can’t say for over parts of the world, especially in America, but salt was broadly commercialized BCE.
