Salt isn’t regularly considered a spice, nor is it discussed as a vitamin like A, B, etc. But isn’t it necessary in small amounts for humans?

Answer 1

It’s not biology, it’s logic: if vitamins are essential it does not mean that every essential stuff is vitamin. E.g. water is essential, but not a vitamin. Neither salt.
