Source of validity: Scientific
Rating (out of 5): 3

Salt, or sodium chloride, has a scientifically recognized relationship with the adrenal cortex, primarily because the adrenal glands produce aldosterone, a hormone essential for regulating sodium and fluid balance in the body. In conditions such as Addison's disease (primary adrenal insufficiency), where the adrenal cortex fails to produce sufficient aldosterone and cortisol, patients often experience salt cravings and are at risk for hyponatremia (low blood sodium). Medical management of Addison’s disease and related adrenal insufficiencies includes dietary salt supplementation to help maintain electrolyte and fluid balance. However, for the general population without adrenal insufficiency, there is no clinical evidence that increasing salt intake has any beneficial effect on adrenal cortex function or overall adrenal health. Excessive salt intake can, in fact, be harmful, leading to elevated blood pressure and other cardiovascular risks. In summary, while there is scientific evidence supporting the use of salt in specific adrenal cortex disorders such as Addison's disease, its use as a general adrenal support supplement in healthy individuals is not supported by research.
