Table salt is #97% to 99%# sodium chloride, with trace elements of other salts, plus added anti-clumping agents and iodine added during processing. In that respect it is a crystalline mixture.


Sodium in moderation is necessary to all animal life where it keeps our nerves and muscles working. Additives in table salt include iodine to keep thyroids healthy.

Anti-clumping agents keep salt from becoming a large solid ball in the presence of moisture. In some countries salts of iron are also added to table salt to contend with iron deficiency anemia.
