ashwagandha

Ashwagandha is discussed as an effective supplement for lowering cortisol levels in the episode titled "How to Control Your Cortisol & Overcome Burnout" on the Huberman Lab. According to Andrew Huberman, studies indicate that ashwagandha can reduce cortisol levels by approximately 10% to 29%.

Key Points:

• Recommended Dosage: Starting dosages should be around 300 milligrams, with higher doses (up to 600-900 mg) potentially effective.
• Timing: It is best to take ashwagandha in the late afternoon or evening to effectively lower cortisol without interfering with its natural rise in the morning.
• Considerations: It's advised to prioritize other cortisol-reduction strategies before supplementing with ashwagandha for optimal results 1.

Ashwagandha offers several significant health benefits, primarily related to stress reduction and its effects on overall well-being. Here are the key benefits highlighted by Andrew Huberman in the Huberman Lab:

Benefits of Ashwagandha

1. Anxiolytic Effects: Ashwagandha has a powerful anti-anxiety effect, demonstrated in numerous studies showing its efficacy in reducing anxiety levels in stressed individuals 1.

2. Cortisol Reduction: It is effective in lowering cortisol levels by approximately 14.5% to 27.9% in otherwise healthy but stressed humans, which is significant compared to many other supplements 1.

3. Athletic Performance: Ashwagandha has been used to enhance physical performance and power output in athletes.

4. Testosterone Levels: There is evidence suggesting it can modestly increase testosterone levels.

5. Cholesterol Management: It may positively influence low-density lipoprotein (LDL) cholesterol levels, potentially supporting cardiovascular health.

6. Improved Sleep: It is known to help with sleep issues without causing insomnia, making it suitable for evening use 2.

7. Reduction in OCD Symptoms: The herb appears to decrease symptoms of obsessive-compulsive disorder (OCD), impacting both obsessions and compulsions.

8. Enhanced Memory and Cognitive Function: Some studies suggest improvements in memory and cognitive performance, potentially linked to reduced cortisol levels and improved sleep quality.

Usage Considerations

While ashwagandha is generally considered safe, it is recommended to evaluate individual responses and consult with healthcare providers before starting supplementation, especially regarding long-term use and potential implications for thyroid function 3.

Ashwagandha reduces stress primarily through its effects on cortisol, the body's main stress hormone. According to Andrew Huberman, research indicates that ashwagandha can lower cortisol levels by 14.5% to 27.9% in stressed individuals, which is significant compared to many other supplements available on the market 1.

Mechanisms of Action

1. Reduction of Cortisol: Ashwagandha inhibits the production of cortisol, helping to alleviate the physiological effects associated with chronic stress, such as anxiety and fatigue. This reduction is particularly beneficial during times of acute stress.

2. Anxiolytic Effects: Ashwagandha is noted for its powerful anti-anxiety effects, which can help individuals manage stress more effectively. In various studies, it has demonstrated marked improvements in anxiety levels 2.

3. Impact on Brain Chemistry: The herb interacts with the GABA system and other neurotransmitter systems, promoting a sense of calmness and well-being, further assisting in stress management and relaxation.

4. Sleep Quality Improvement: By reducing stress and cortisol levels, ashwagandha may also enhance sleep quality—a critical factor in stress recovery. Poor sleep can exacerbate stress levels, creating a vicious cycle.

5. Downstream Health Benefits: Lowering cortisol can lead to improvements in cardiovascular health, decrease symptoms of OCD, and even enhance cognitive function due to better sleep and reduced physiological burden from stress 3.

Usage Recommendations

While ashwagandha can be beneficial for managing stress, Andrew Huberman advises caution regarding long-term use. He suggests that it should not be taken on a daily basis for extended periods—ideally, it is used during particularly stressful times rather than year-round.

For optimal results, it may be best to take ashwagandha in the evening, as it tends not to cause insomnia 1. Always consult with healthcare providers before beginning any new supplementation regimen, especially regarding dosages and long-term safety practices.
