These salts have slight differences in taste and big differences in geography.
Real Salt and Himalayan salts have a lot in common. Both are harvested from ancient salt deposits that were created long before there were any modern pollutants. And geologically, the Himalayan deposit is very similar to the Real Salt deposit, since they both contain a full spectrum of minerals. Both Himalayan salts and Real Salt are considered crystal salts too.
There is, however, a slight difference in flavor between the two. Real Salt is a tad sweeter, while Himalayan is a bit earthier. The biggest difference between Real Salt and Himalayan salt, though, is geography—Real Salt is mined in Utah and Himalayan salt is mined in Pakistan. That means, if you live in the U.S. (or anywhere in North America, for that matter), Real Salt is the more sustainable option since it means fewer miles from mine to table.
