Rating (out of 5): 2

Sea salt has been used traditionally in various cultures as a remedy for fatigue and to "support" the adrenal glands, especially in folk medicine and some forms of alternative medicine. The rationale is based on the idea that the adrenal glands, which produce hormones like cortisol and aldosterone, depend on proper sodium balance for optimal function. Proponents claim that adding a pinch of sea salt to water can help restore electrolytes and support adrenal health, particularly in those experiencing symptoms of "adrenal fatigue" (a term not widely recognized in mainstream medicine).

However, scientific validation for this practice is limited. While sodium (from any salt, including sea salt) is essential for fluid balance and blood pressure regulation — both influenced by adrenal hormones — there is no robust evidence that sea salt specifically "supports" the adrenal glands beyond its general role in maintaining electrolyte balance. Most scientific literature addresses salt’s importance in acute adrenal insufficiency (Addison’s disease), where salt cravings and sodium loss are symptoms, and salt supplementation may be required under medical supervision. For otherwise healthy individuals, there’s no clinical evidence that sea salt confers additional benefits for adrenal function compared to regular table salt.

In summary, the use of sea salt to support adrenal glands is rooted in traditional practices rather than strong scientific evidence, and claims of adrenal support should be approached with caution.
