Understanding Andrew Huberman's Ashwagandha Recommendations
Andrew Huberman, a neuroscientist and host of the Huberman Lab podcast, has discussed his use of ashwagandha for managing stress and improving sleep. His recommendations are informed by personal experience and scientific literature. He typically suggests a dosage between 300–600 mg per day, taken in the evening to align with the body's natural cortisol rhythms.
The Importance of Cycling Ashwagandha
Cycling ashwagandha is a critical part of Huberman's advice. He advises against high doses for extended periods to avoid potential negative impacts on hormone and neurotransmitter pathways. A common protocol involves taking ashwagandha for two weeks, followed by a two-week break. This prevents the body from becoming overly dependent on the supplement for cortisol regulation and allows the body's natural systems to reset.
Timing Your Ashwagandha Intake
For most, taking ashwagandha in the evening is the recommended approach. This is because ashwagandha's primary effect is to lower cortisol. The body produces a cortisol spike in the morning, which helps with wakefulness and energy. Evening intake helps lower cortisol levels as you prepare for the night, which promotes relaxation and better sleep quality. Huberman sometimes takes it with his last meal, a couple of hours before bed.
Ashwagandha for Different Goals
Ashwagandha is used for various purposes. While Huberman's recommendations focus on stress and sleep, it is worth noting other applications supported by research. The dosage can vary depending on the desired outcome, as shown in the table below.
| Purpose | Typical Dosage Range | Considerations |
|---|---|---|
| Stress & Anxiety | 300–600 mg per day | Evening intake helps lower cortisol; cycling is recommended. |
| Improved Sleep | 600 mg or more per day | Best results often seen with consistent use over 8+ weeks. |
| Enhanced Athletic Performance | 500–1,000 mg per day | Some studies split this into two daily doses. |
| Cognitive Function | 300–600 mg per day | Focuses on memory and attention, potentially linked to reduced stress. |
Consult a healthcare professional before starting any new supplement regimen, especially when aiming for higher doses or for specific health goals.
Potential Side Effects and Precautions
While generally well-tolerated, ashwagandha can cause side effects, particularly at higher doses. Stomach upset, diarrhea, and vomiting are among the most common adverse reactions. Long-term effects of high-dose supplementation are not yet fully understood, reinforcing the importance of a conservative approach and cycling. Individuals with certain conditions, such as autoimmune disorders or thyroid issues, should consult a doctor before taking ashwagandha, as it can stimulate the immune system and affect thyroid hormone levels. Pregnant and breastfeeding women are also advised to avoid it.
What to Look for in an Ashwagandha Supplement
Selecting a quality supplement is crucial. Huberman often directs people to third-party vetted resources like Examine.com for detailed guidance. High-quality ashwagandha supplements are typically standardized to a specific percentage of withanolides, the plant's active compounds. Common forms include root powder, extracts, and capsules. Look for products that have been independently verified by organizations like USP or NSF International to ensure purity and potency.
Conclusion: Responsible Ashwagandha Use
Andrew Huberman's recommendations for ashwagandha are scientifically informed and practical, emphasizing responsible use. By adhering to a modest daily dosage, cycling the supplement, and timing it for evening intake, users can leverage its stress-reducing and sleep-enhancing benefits. Always prioritize consultation with a healthcare professional to ensure it aligns with individual health needs and to avoid potential complications. His guidance, found in various podcast episodes and resources, advocates for an evidence-based approach to wellness.

Frequently Asked Questions
What are the main benefits of ashwagandha according to Huberman?
Andrew Huberman highlights ashwagandha primarily for its potent effects on lowering cortisol levels, which helps reduce stress and improve sleep quality. He also notes its potential indirect role in modestly increasing testosterone by reducing the counteracting effects of high cortisol.
How long should I take ashwagandha for?
Huberman advises cycling ashwagandha to prevent the body from adapting and to avoid potential disruptions to hormonal pathways with chronic use. He has mentioned a protocol of using it for up to two weeks at a time.
Is it safe to take ashwagandha every day?
While many people tolerate daily ashwagandha, Huberman recommends cycling it, especially when taking higher doses. For some individuals, taking it every day for a short period is fine, but long-term continuous use is not advised.
Why does Huberman recommend taking ashwagandha in the evening?
Huberman recommends evening intake because ashwagandha reduces cortisol. The goal is to avoid interfering with the natural morning cortisol spike that promotes wakefulness and energy. Taking it in the evening supports the natural decline of cortisol, aiding relaxation and sleep.
Can I take ashwagandha in the morning?
While you can take it in the morning, Huberman cautions against it due to its cortisol-lowering effects. An evening dose is more strategic for supporting sleep and managing overall stress levels without impacting morning energy.
What happens if I don't cycle ashwagandha?
Not cycling ashwagandha could lead to potential down-regulation of natural hormone systems and neurotransmitter pathways, according to Huberman. This could reduce the supplement's effectiveness over time and potentially cause unintended hormonal shifts.
What specific type of ashwagandha should I use?
Huberman suggests referencing reliable resources like Examine.com for information on specific forms and dosages used in studies. The most effective supplements are often standardized extracts, such as KSM-66, which is backed by research and ensures a consistent level of active compounds.
Does Andrew Huberman recommend ashwagandha for everyone?
No, Huberman emphasizes that supplements are highly individual. He consistently advises consulting a healthcare provider before starting any new supplement, including ashwagandha, to ensure it is appropriate for your specific health profile and goals.
How quickly does ashwagandha take effect?
Many studies show ashwagandha's benefits appearing after consistent daily use over several weeks. While some people may feel a difference sooner, effects like improved sleep and reduced anxiety are more prominent with longer-term use.
