Table salt vs. sea salt

Salt is a mineral consisting primarily of sodium chloride (NaCl) and  is essential for life in general.

Table salt is typically mined from underground salt deposits. Table salt is more heavily processed to eliminate minerals and usually contains an additive to prevent clumping. Most table salt also has added iodine, an essential nutrient that helps maintain a healthy thyroid.


Sea salt comes from evaporating seawater, so it is a natural source of sodium. Table salt comes from mining salt deposits. Manufacturers then process it into a fine crystal that is easy to mix in food.

Although people may perceive sea salt to be better for health, it has the same sodium content as table salt. Some people believe that sea salt has less sodium than table salt, but this is a misconception.


Sea salt and table salt have the same basic nutritional value, despite the fact that sea salt is often promoted as being healthier. Sea salt and table salt contain comparable amounts of sodium by weight.

Whichever type of salt you enjoy, do so in moderation. The Dietary Guidelines for Americans recommend limiting sodium to less than 2,300 milligrams a day.
