When to Take Ashwagandha: Morning vs Night (and Why It Matters)
Timing your adaptogens isn't arbitrary. We break down the cortisol-circadian rhythm connection and optimal dosing windows.
Ashwagandha's timing matters more than most people realise, because it works primarily by modulating the HPA (hypothalamic-pituitary-adrenal) axis — the system that regulates cortisol production.
Cortisol follows a circadian rhythm: it peaks 30–45 minutes after waking and gradually declines through the day. This has direct implications for Ashwagandha timing.
For stress and anxiety: taking Ashwagandha in the morning is generally recommended — you want it working during the day when stressors are active. A 2019 RCT used 240mg/day in the morning with significant outcomes for perceived stress.
For sleep: taking it at night (30–60 minutes before bed) leverages its GABAergic activity. Sominone, a withanolide, binds GABA receptors, promoting sleep onset and quality. A 2020 trial found 300mg before bed significantly improved sleep efficiency.
Our recommendation: for combined benefits, split the dose — half in the morning with food, half before bed. Start with 250–300mg total and work up based on response.
