Our Betti Cleanse natural sea salt is made by evaporating fresh sea water in shallow pools within solar greenhouses. Coarse crystals are formed as the ocean water evaporates, leaving behind pure sea salt crystals. Our salt is that pure! The moisture in sea salt is an indication that it is a natural product. Sea salt attracts moisture from the atmosphere, which is why standard table salt has drying agents added to provide a more free-flowing product. Sea salt does not flow well in a shaker. Beware of some sea salt that has been processed and really isn't much different than table salt. The differences are difficult to distinguish. There is no organic trade association or government label for organic sea salt in the U.S. salt works
