Adrenal Cortisol Test Kit

An at-home saliva test measuring your cortisol at four points across the day — morning, noon, afternoon, and night. Get a more detailed picture of your cortisol patterns from home — no lab visit, no waiting room. Cortisol moves through the day, rising and falling alongside your temperature and energy. Measuring it at four points reveals the patterns behind fatigue, brain fog, and slow metabolism — and whether your cortisol may be dysregulated.† (Please note: not available in NY, CA, or MD due to state regulations on at-home lab testing.)
