Sea salt is produced by evaporating ocean water and undergoes less processing than table salt. Because of this, it retains trace minerals like magnesium, potassium, and calcium. It supports electrolyte balance, aids digestion, and is often used topically in baths to soothe irritated skin.

While sea salt is minimally processed, it is chemically composed almost entirely of sodium chloride—just like table salt. Therefore, it carries the same potential cardiovascular risks if consumed in excess. Health experts, such as the American Heart Association, advise consuming all forms of sodium in moderation.
