Introduction
Ashwagandha, a popular adaptogenic herb, has been used in Ayurvedic medicine for centuries to help the body manage stress and promote overall well-being.
Recently, scientific studies have explored its potential effects on reducing cortisol levels, the body’s primary stress hormone. When incorporating ashwagandha into your routine, most clinical studies suggest a dosage of 300–600 mg per day.
It's best to begin with a lower dose and gradually increase it to assess how your body responds.
Understanding Cortisol and Stress Response
Cortisol is produced by the adrenal glands and plays a crucial role in regulating metabolism, immune response, and blood sugar levels.
When the body perceives stress, cortisol levels increase to prepare the body for a “fight-or-flight” response. However, chronically elevated cortisol levels can have negative effects, including:
- Anxiety
- Insomnia
- Weight gain
- Impaired immune function

Scientific Evidence on Ashwagandha and Cortisol
Research suggests that Ashwagandha may potentially modulate the hypothalamic-pituitary-adrenal (HPA) axis, which controls the body’s response to stress, thereby supporting cortisol balance.
Key Studies on Cortisol Reduction
- Chandrasekhar et al. (2012) conducted a double-blind, placebo-controlled study on adults experiencing chronic stress. Participants taking 300 mg of Ashwagandha twice daily for 60 days reported a significant reduction in serum cortisol levels by up to 30% compared to the placebo group (Chandrasekhar et al., 2012).
- Lopresti et al. (2019) investigated the effects of Ashwagandha supplementation on stress and anxiety. Results indicated that individuals taking 240 mg of Ashwagandha extract daily showed a reduction in perceived stress and a corresponding decline in cortisol levels (Lopresti et al., 2019).
- Salve et al. (2019) studied 60 healthy adults over eight weeks and found that those taking Ashwagandha experienced lower cortisol levels and reported improved sleep quality and emotional well-being (Salve et al., 2019).
While these studies demonstrate promising results, it is important to note that more large-scale studies are needed to fully confirm these findings.

How Could Ashwagandha Help Manage Cortisol?
1. Regulation of the HPA Axis
Ashwagandha may help modulate the HPA axis, preventing excessive cortisol release during prolonged periods of stress. Balancing this system might promote a healthier stress response.
2. Impact on GABA and Neurotransmitters
Ashwagandha is believed to influence GABA receptors, promoting relaxation and a sense of calm. This effect may indirectly reduce cortisol levels by enhancing the body’s ability to cope with stress.
3. Support for Emotional Balance and Wellbeing
Ashwagandha is considered an adaptogen and may help support emotional balance and general well-being. It may contribute to mental and physical well-being, particularly during times of fatigue, tension, or reduced concentration. These traditional uses suggest it could be a supportive tool for managing everyday stress.

Other Potential Benefits of Balanced Cortisol
Balancing cortisol levels through Ashwagandha supplementation may offer the following potential benefits:
- Reduced Anxiety and Stress: Lower cortisol levels might help reduce feelings of anxiety and enhance overall emotional well-being.
- Improved Sleep Quality: High cortisol can interfere with sleep. Ashwagandha may promote relaxation and better sleep patterns.
- Increased Energy and Reduced Fatigue: By supporting stress resilience, Ashwagandha may improve energy levels and reduce fatigue.
- Support for Immune Health: Lower cortisol levels are associated with a stronger immune response, which may enhance overall immunity.
- Supports Mental and Physical Capacities During Stress: Ashwagandha may help maintain physical and mental capacities in cases of weakness, exhaustion, tiredness, and loss of concentration — effects commonly associated with prolonged stress.
How to Take Ashwagandha for Cortisol Management
Recommended Dosage
Most clinical studies have used dosages between 300–600 mg per day. It is typically recommended to start with a lower dose and gradually increase it to assess tolerance. For high-quality options, consider ashwagandha capsules, which offer high bioavailability and standardised extracts.
Best Time to Take Ashwagandha
- Morning: To enhance focus and energy throughout the day.
- Evening: To promote relaxation and improve sleep quality.
Duration of Supplementation
Noticeable effects on stress and cortisol levels are usually observed after 6–8 weeks of consistent use.
