Synopsis

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

Sodium is traditionally considered important for supporting adrenal function, particularly in the context of adrenal insufficiency or "adrenal fatigue," a concept more commonly found in alternative and integrative medicine. The adrenal cortex is responsible for producing hormones like aldosterone, which regulates sodium and potassium balance in the body. When adrenal function is compromised (as in Addison's disease), sodium loss can occur, leading to symptoms like low blood pressure, fatigue, and salt cravings. In response, traditional naturopathic and holistic health practices often recommend increasing dietary sodium or using salt supplements to support adrenal health.

However, scientific validation for routine sodium supplementation in the general population for adrenal support is limited. In cases of diagnosed adrenal insufficiency, sodium replacement is medically indicated and well-established. For individuals without clear adrenal pathology, there is little evidence that sodium supplementation improves adrenal cortex function or overall health. The traditional use is based more on symptom relief (e.g., addressing salt cravings or low blood pressure) than on direct evidence of adrenal restoration. Excess sodium intake can have negative cardiovascular effects, so supplementation should be approached cautiously and under medical supervision.

In summary, sodium's role in supporting the adrenal cortex is rooted in tradition and specific clinical scenarios, with limited scientific validation for its use in otherwise healthy individuals.
