The "Adrenal Cocktail" Is Juice, Coconut Water and Salt, and "Adrenal Fatigue" Is Not a Diagnosis

The drink exists to address adrenal fatigue, and that premise does not hold up. A systematic review screened 3,470 articles and analysed 58 studies of cortisol and fatigue; results conflicted across tests and designs, and the authors concluded there is no substantiation that adrenal fatigue is an actual medical condition¹.

The Endocrine Society says no scientific proof supports adrenal fatigue as a true condition and no test can detect it². It warns that tiredness, poor sleep and salt cravings are non-specific and can reflect adrenal insufficiency, depression or obstructive sleep apnea, which need a real diagnosis². It also notes that adrenal hormone supplements taken without need can shut down the adrenal glands and risk adrenal crisis when stopped².

The main risk is potassium. Orange juice provides about 496 mg per cup⁴. In people with chronic kidney disease or taking ACE inhibitors or potassium-sparing diuretics, even dietary potassium below the usual adequate intake can cause hyperkalemia, which in severe cases causes muscle weakness and dangerous heart rhythms; ARBs also reduce potassium excretion⁴. Hyperkalemia can also occur with adrenal insufficiency⁴, one of the real conditions the Endocrine Society says unexplained tiredness can signal².

Cream of tartar adds more. Two people who ate large amounts of it to "clean themselves out" vomited, had serum potassium above 8.0 mmol/L and peaked T waves on their ECGs, and both recovered after hospital care for hyperkalemia⁵. A pinch is far less than those intakes, but it still adds potassium for people who need to limit it^4,5.

The adrenal cocktail is a juice drink built on a diagnosis endocrinologists reject^1,2. Persistent tiredness deserves a real work-up².
