What it is
Regulatory status: Food ingredient.
Evidence basis: Human clinical evidence
Sodium and chloride are essential electrolytes involved in fluid balance, nerve signaling and muscle contraction. Intake needs rise with substantial sweat loss, but routine excess sodium raises blood pressure in many people; a pinch of sea salt is still sodium chloride.
