Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Salt (sodium chloride) has a long history of traditional use related to supporting the adrenal glands, largely stemming from the belief that individuals with adrenal insufficiency or so-called "adrenal fatigue" may benefit from increased salt intake. The adrenal glands produce hormones, including aldosterone, which helps regulate sodium and water balance. In conditions like Addison’s disease (a form of adrenal insufficiency), the body can lose too much sodium, making salt supplementation medically necessary. Outside of this specific context, however, the idea that salt broadly supports adrenal function in healthy individuals or those with "adrenal fatigue" is mostly based on tradition and anecdotal reports rather than robust scientific evidence. While some practitioners recommend salt to address symptoms like low blood pressure or fatigue, clinical trials supporting its efficacy for general adrenal support are lacking. Excessive salt intake can also contribute to negative health outcomes, such as hypertension. In summary, while salt is essential for life and has a role in adrenal insufficiency, its use for general adrenal support is traditional rather than scientifically validated.
