Does Ashwagandha Raise Cortisol? Unveiling the Truth
Preliminary research suggests that ashwagandha, an adaptogenic herb, generally does not raise cortisol levels. Instead, it is often associated with helping to regulate and potentially lower cortisol, particularly in individuals experiencing chronic stress.
Ashwagandha: An Ancient Remedy for Modern Stress
Ashwagandha (Withania somnifera), also known as Indian ginseng or winter cherry, is a cornerstone of Ayurvedic medicine, revered for its adaptogenic properties. Adaptogens are natural substances believed to help the body resist various stressors – physical, chemical, and biological. For centuries, it’s been used to enhance energy levels, reduce stress, and improve overall well-being. But in today’s fast-paced world, a pressing question arises: Does Ashwagandha Raise Cortisol? Or does it offer a solution to our modern stress epidemic?
The Science of Cortisol and Stress
Cortisol, often dubbed the “stress hormone,” plays a crucial role in the body’s response to stress. It’s produced by the adrenal glands and is involved in regulating blood sugar, metabolism, and immune function. Elevated cortisol levels, particularly chronically elevated levels, can lead to a range of health issues, including:
- Weight gain
- Sleep disturbances
- Weakened immune system
- Anxiety and depression
- Digestive problems
Understanding how various substances, including ashwagandha, influence cortisol levels is crucial for managing stress and promoting overall health.
Ashwagandha’s Impact on Cortisol Levels: Evidence-Based Insights
Numerous studies have investigated ashwagandha’s effects on cortisol levels. The prevailing evidence suggests that ashwagandha generally helps to regulate and, in many cases, lower cortisol levels. This effect is attributed to its adaptogenic properties, which help the body adapt to stress and maintain homeostasis.
Several studies indicate that ashwagandha supplementation can lead to a statistically significant reduction in cortisol levels, particularly in individuals experiencing chronic stress. These studies typically involve comparing ashwagandha supplementation to a placebo control group. The results consistently point towards a cortisol-lowering effect for ashwagandha.
How Ashwagandha Works: A Potential Mechanism
While the exact mechanisms are still being investigated, it is believed that ashwagandha impacts the hypothalamic-pituitary-adrenal (HPA) axis, the body’s central stress response system. By influencing the HPA axis, ashwagandha may help to:
- Reduce the body’s overall stress response
- Modulate the release of cortisol
- Promote a sense of calm and relaxation
It’s important to note that individual responses to ashwagandha can vary. Factors such as dosage, duration of use, and individual differences in physiology can all influence the herb’s effects on cortisol levels.

Potential Side Effects and Precautions
While generally considered safe, ashwagandha can cause side effects in some individuals. These may include:
- Digestive upset
- Drowsiness
- Headache
- Thyroid issues (in some cases)
It is important to consult with a healthcare professional before taking ashwagandha, especially if you have any underlying health conditions or are taking medications. Ashwagandha is not recommended for pregnant or breastfeeding women.
Frequently Asked Questions
Does Ashwagandha Always Lower Cortisol?
No, while studies generally show a reduction in cortisol, individual responses can vary. Ashwagandha’s effect is more about regulating the stress response, so if someone’s cortisol is already low, it may not lower it further. The key is that it helps the body adapt and maintain homeostasis.
Is Ashwagandha Safe for Everyone?
While generally considered safe, ashwagandha isn’t suitable for everyone. Pregnant and breastfeeding women should avoid it. People with autoimmune conditions or thyroid issues should consult a healthcare professional before use. Some people may experience mild side effects like digestive upset.
How Long Does it Take for Ashwagandha to Lower Cortisol?
The timeline for seeing noticeable effects can vary, but many studies suggest that improvements can be seen within 4-12 weeks of consistent use. Factors like dosage, individual physiology, and stress levels can influence the timeframe.
Can Ashwagandha Interact with Medications?
Yes, ashwagandha can potentially interact with certain medications, including immunosuppressants, sedatives, and thyroid medications. It’s crucial to consult with a healthcare professional before taking ashwagandha if you are on any medication.
What’s the Best Time of Day to Take Ashwagandha?
